The pottery vessels from the Mijiaya site reveal, to our knowledge,
the first direct evidence of in situ beer making in China, based on
the analyses of starch, phytolith, and chemical residues. Our data
reveal a surprising beer recipe in which broomcorn millet (Panicum
miliaceum), barley (Hordeum vulgare), Jobs tears (Coix lacryma-
jobi), and tubers were fermented together. The results indicate
that people in China established advanced beer-brewing technol-
ogy by using specialized tools and creating favorable fermenta-
tion conditions around 5,000 y ago. Our findings imply that early
beer making may have motivated the initial translocation of bar-
ley from the Western Eurasia into the Central Plain of China before
the crop became a part of agricultural subsistence in the region
3,000 y later.
Yangshao period
starch analysis
phytolith analysis
archaeological chemistry
In China, the earliest written record of beer appears in oracle bone
inscriptions from the late Shang dynasty (ca. 12501046 BC)
(1, 2). According to the inscriptions, the Shang people used malted
grains, including millets and barley/wheat (barley and wheat
are represented by the same Chinese character, lai)asthemain
brewing ingredients (1, 3). Scholars have hypothesized that the
Shang tradition of beer brewing has its origin in the Neolithic
Yangshao period (50002900 BC), when large-scale agricultural
villages were established in the Yellow River valley (46). The
hypothesis is possible, considering that China has an early tradition
of fermentation and evidence of rice-based fermented beverage has
been found from the 9,000-y-old Jiahu site (7). Certain types of
Yangshao vessels, including funnels and jiandiping (pointed-bottom
vessel) amphorae, show stylistic similarities to the brewing equip-
ment in the historical period and modern ethnographic records (6).
However, direct evidence for alcohol production from Yangshao
The Mijiaya site is located on a primary terrace northeast of
the Chan River, a tributary of the Wei River, in Shaanxi, North
China (Fig. 1 and SI Text). The excavations revealed two sub-
terranean pits with artifacts that appeared to resemble in situ
beer-brewing facilities (8) (Fig. 2 and Fig. S1). Both pits belong
to Banpo IV (or late Yangshao period) stratum, and an estab-
lished chronology based on ceramic typology and
the region securely places the time period between 3400 and
2900 BC (9, 10). Pit H82 was 3.7-m deep with straight walls and
five steps leading down to the bottom (Fig. 2A); Pit H78 was
2.52.7 m deep with a flat bottom and a secondary platform on
one side of the walls (8). Three types of vessels were recovered in
both pits: wide-mouth pots, funnels, and jiandiping amphorae (Fig.
2BD), all of which have yellowish residues on their interior
surface (Fig. S2). The shapes and styles of the vessels suggest three
distinctive stages in the beer-making process: brewing, filtration,
and storage. Interestingly, each pit also contained a pottery stove
(Fig. 2E). In brewing activity, heating equipment is often used to
maintain the optimal temperature for mashing. The stoves would
have been especially suitable for this operation. Our hypothesis is
that the artifact assemblages exclusively from the two pits repre-
sent a beer-making toolkit.To test our hypothesis, we conducted
starch, phytolith, and chemical analyses on the residues from two
complete funnels and pottery sherds from five jiandiping ampho-
rae and two wide-mouth pots.
Taxonomical Identification
The identification of starch grains and phytoliths was based on
morphological and morphometric analyses. The morphological
identification relied on a reference collection from over 1,000 Asian
and European economically important plant specimens, and by
consultation with published literature (1116) (Table S1). For
morphometric analysis, we applied two computer-assisted methods.
First, a discriminant analysis model was used to separate the starch
grains of Jobstears(Coix lacryma-jobi ) from those of millets
(Setaria italica and Panicum miliaceum). Based on three variables,
including size, eccentricity of the hilum, and presence or absence of
curved arms on the extinction cross, this multivariate model has a
success rate of 82.4% for separating Jobs tears from millets (17).
Second, we conducted a morphometric analysis of the articulated
dendritic phytoliths. Dendritics are produced in the inflorescence
bracts of many common cereals, especially Triticeae species. Ar-
ticulated dendritics produce wave patterns of taxonomic signifi-
cance. Recent research has achieved good success at identifying
wheat and barley phytoliths and distinguishing them from the rel-
evant wild grasses (12, 13). A sample size as small as 30 dendritic
wave lobes can be adequate for a 90% confidence level in dis-
criminating among taxa based on differences in several wave lobe-
shaped morphometries. We measured the wave lobes of articulated
dendritic phytoliths from six Mijiaya residue samples following the
procedures outlined by Ball et al. (18). Each residue sample yielded
at least 30 measurable wave lobes in total, which allowed us to have
statistical confidence in the measurements of form factor, round-
ness, convexity, solidity, compactness, and aspect ratio (Table S2).
We compared the means of these six morphometries for the Mijiaya
dendritics from each sample with the range of means observed in 20
Triticeae and other dendritic-producing species, including common

wild species indigenous to China and domesticated species in-
troduced into China from Western Eurasia (Tables S3 and S4).
A total of 541 starch grains were recovered from the funnels and
pottery sherds (Table 1). Of these grains, 488 starch grains (90.2%
of the total) were identifiable to various taxonomic levels com-
pared with our reference data. The starch assemblage mainly
consists of millet, Triticeae, and Jobstears,withasmallercontri-
bution from tubers that include snake gourd root (Trichosanthes
kirilowii), yam (Dioscorea sp.), and lily (Lilium sp.) (Fig. 3 AF). A
high percentage of starch grains (n=166, 30.7%) exhibit signs of
damage, and among them two types of damage closely resemble
that produced by beer brewing. First, some grains show pits and
channels on their surface, ranging from being slightly pitted to
completely hollow (Fig. 4A). Second, a large number of starch
grains are swollen, folded, and distorted (Fig. 4B); some still retain
their individual boundaries, but many merge into one another.
These two damage patterns precisely match the morphological
changes developed during malting and mashing, as we observed in
our brewing experiments and that reported in published literature
(Fig. 4 Cand D,Fig. S3,andSI Materials and Methods)(1922).
During malting, enzymes in sprouting cereals break down starch to
dextrins and simple sugars, creating typical surface pits and interior
channels in the grains (19). Furthermore, mashing involves heating
of the malt in water for a period, which causes gelatinization,
swelling, folding, and distortion of starch grains (19). Thus, the
damaged state of the starch grains in our archeological sample
provides strong evidence for the conclusion that those starch grains
are residues from the brewing process.
Phytolith data indicate the presence of cereal husks (Table 2).
Phytoliths identified to the Panicoideae grass subfamily pre-
dominate the assemblage. Seven vessels revealed η-shaped long
cells that are consistent with phytoliths formed in epidermal husk
tissues of broomcorn millet (Fig. 3J) (15). Cross-shaped phytoliths
showing a considerable variation in form and size, comparable with
the crosses produced by Jobs tears in our modern references, were
observed (Fig. 3H). Phytolith forms produced in Pooideae were
also identified. In particular, articulated dendritic phytoliths con-
sistent in pattern and shape with those produced in the husks of
Triticeae species were observed (Fig. 3K). Our morphometric
analysis of the articulated dendritics indicates their most probable
origin to be from the inflorescence bracts of barley (Hordeum vul-
gare). Although some of the mean measurements of the archaeo-
logical samples fall within the ranges of other taxa, all of the means
fall within those observed in H. vulgare (Tables S5 and S6). The
profile of phytoliths corroborates the starch grain assemblage, in-
dicating the presence of broomcorn millet, Jobs tears, and barley.
Our ion chromatographic (IC) analysis identified the presence of
oxalate, which develops during the steeping, mashing, and fer-
mentation of cereals (23). Calcium oxalate is a principle component
of beerstone,whichsettlesoutatthebeer fermentation and
storage containers, and has been used as a compound marker for
identifying barley beer fermentation in ancient vessels (2427). We
conducted tests on the residues from Funnel 1, Pot 3, and Pot 5.
The results confirmed that high levels of oxalate are present in
Funnel 1 and Pot 5 (Fig. 5). Oxalate was not detected from Pot 3.
The oxalate concentration is 0.08% (80 mg/100 g) for Funnel 1 and
0.05% (50 mg/100 g) for Pot 5. Although oxalates occur naturally in
plants like spinach (Spinacia oleracea), rhubarb (Rheum rhabarba-
rum), and some Dioscorea and Lilium species, the vessel types in
this study are not suitable for storing any fresh plant.
To rule out the potential contamination from the enclosing soil
matrix and postexcavation conditions, we analyzed four samples as
control specimens. Three samples were analyzed for starch and
phytolith, including one from the sediment adhering to the exterior
surface of Pot 5 (control sample 1), one from a stone adze fragment
recovered from Pit H78 (control sample 2), and one from the
plaster material used for reconstructing Funnel 2 (control sample 3)
(Fig. S1). Compared with ancient samples, the control samples
contained a much smaller number of phytoliths and starch grains
(Tables 1 and 2) with no signs of damage. IC analysis of the exterior
scrapings from Pot 5 (control sample 4) detected no oxalate, a
result in clear contrast to a high level of oxalate found in the in-
terior surface of the same vessel. These observations suggest that
the high concentrations of starch, phytolith, and chemical residues
related to the beer-making process are exclusively present on the
interior surfaces of the Mijiaya vessels, which potentially have had
direct association with beer brewing.
Discussion and Conclusion
All three lines of evidence are consistent with the archaeological
data, indicating that the Yangshao people brewed a mixed beer with
specialized tools and knowledge of temperature control. Our data
show that the Yangshao people developed a complicated fermen-
tation method by malting and mashing different starchy plants.
Compared with millets, barley has much higher α-andβ-amylase
activities, which promotes the saccharification process (28). Tubers

contribute starch and sugars for fermentation, and they also add a
sweeter flavor to the beer. The Yangshao people probably de-
veloped their recipe through repeated experiments.
The discovery of barley in the beer residues suggests a social
motivation in the initial stage of crop translocation (29). Barley
was first domesticated in Western Eurasia and later introduced
into China, presumably through the Central Asian steppe. The
timing and nature of the crops initial adoption in China is still
not well understood (2931). In the Central Plain, macro-
botanical remains from the Yangshao sites are generally well
preserved, dominated by millets and very few other cereal
types, and no evidence of barley has been reported. The ear-
liest evidence of barley comes from some sporadic finds in
Bronze Age sites, all dated around or after 2000 BC (31, 32).
Not until the Han dynasty (206 BCAD 220), three millennia
after Mijiaya, had this crop become an important part of

subsistence in the Central Plain (29, 33). The microbotanical
remains of barley at Mijiaya account for the earliest occur-
rence of this crop in China.
It is possible that the few rare finds of barley in the Central
Plain during the Bronze Age indicate their earlier introduction
as rare, exotic food. The Mijiaya farmers probably obtained small
quantities of barley grains through exchange or cultivated the
plant along with other cereals. We suggest that barley was ini-
tially introduced to the Central Plain as an ingredient for alcohol
production rather than for subsistence. Because to our knowl-
edge this is the first study that applies morphometric analysis to
the dendritic phytoliths from China, future research with more
comprehensive phytolith data from other Neolithic contexts is
needed to test our hypothesis.
The practice of beer brewing is likely to have been associated
with the increased social complexity in the Central Plain during
the fourth millennium BC The late Yangshao period in the Wei
River region was characterized by hierarchically organized
settlement patterns, interpolity competitions, construction of
large public architectures at regional centers, and ritual feasting
likely organized by elite individuals and involving alcohol
consumption (34) (SI Text). Like other alcoholic beverages,
beer is one of the most widely used and versatile drugs in the
world (35), and it has been used for negotiating different kinds
of social relationships. The coincidence of beer production with
other lines of material evidence suggests that competitive
feasting was actively developing. The production and con-
sumption of Yangshao beer may have contributed to the
emergence of hierarchical societies in the Central Plain, the
region known as the cradle of Chinese civilization.
Materials and Methods
Residue Extraction Methods Summary. Chemical samples and two control
samples (1, 3) were obtained by scraping off the sediments from the pottery
surfaces with clean blades. Other residue samples were extracted by using an
ultrasound bath or an ultrasound toothbrush. Starch and phytolith samples
were floated from the residues using the heavy liquid sodium polytungstate
at a specific gravity of 2.35. Extractions obtained from the residue samples
were mounted in 50% (vol/vol) glycerol and 50% (vol/vol) distilled water on
glass slides and scanned under a Zeiss Axio Scope A1 fitted with polarizing
filters and differential interference contrast (DIC) optics, at 200×and 400×
for both starches and phytoliths. Images were taken using a Zeiss Axiocam
Hrc3 digital camera and Zeiss Axiovision software v4.8. See SI Materials and
Methods for details.
Determination of Oxalate Using IC. Residue samples from Funnel 1, Pot 3, and
Pot 5 were analyzed by a Dionex ICS 5000 with a conductivity detector, in
Zhejiang Research Institute of Chemical Industry. The columns used were an
Ion Pac-AS 11-HC Analytical (250 ×4 mm I.D.) and an Ion Pac AG11-HC guard
column (40 ×4 mm I.D.) with an anion ASRS suppressor, operated at 20 °C.
The eluent was 20 mM KOH and the flow rate was 1.5 mL/min; the injection
loop was 25 μL. Each residue sample produced two experimental samples.
Each experimental sample (0.03 g) was dissolved in 3 mL nitric acid and di-
luted with 50 mL distilled water. Standard solutions were made from
solutions of sodium oxalate in a concentration range between 0.0005 and
0.002 mg/mL. The calibration curve was established by linear regression
analysis of peak height vs. added concentration of oxalate. The detection
limit for oxalate under the given conditions is 0.036%. Control sample 4
was analyzed by a Dionex DX-500 IC with a conductivity detector, in the
Environmental Measurements Facility at Stanford University. The eluent
was 20 mM NAOH and the flow rate was 1 mL/min. Standardized solutions
were made from solutions of oxalic acid in a concentration range between
0.1 and 10 mg/mL. Other laboratory conditions were the same as those
used for the three residue samples.

Further Details of the Mijiaya Site. The Mijiaya site was discovered in
1923 by J. G. Anderson and excavated from 2004 to 2006. The
excavations revealed three separate cultural strata belonging to
established chronology in the region based on ceramic typology with
associated radiocarbon dates: the Banpo IV phase (belonging to
the late Yangshao period, 34002900 BC), the Miaodigou II phase
(28002450 B.C) (36), and the Keshengzhuang phase (24002000
BC) (37). The entire site measures around 45 ha with cultural
deposits 1.54 m in depth. A total of 166 Banpo IV pits were found,
and the majority of them are regular in shape with flat bottoms,
suggesting their initial function as storage pits (8). The ceramic ar-
tifacts from the earliest stratum are Banpo IV styles that are com-
parable to the related sites in the region, including Xiehu in Lantian,
Xijing in Shanxian, and Quanhucun in Huaxian. Pollen analysis
indicates that the climate of the Wei River valley was semiarid
during the Banpo IV phase, characterized by steppe vegetation and
herbaceous plants dominating the pollen assemblage (38).
Social Complexity During the Late Yangshao Period. The settlement
pattern of the late Yangshao period is characterized by site nu-
cleation and a two- or three-tiered settlement hierarchy. Several
large regional centers emerged along the Wei River valley for the
first time, including Dadiwan (100 ha) and Gaositou in Gansu and
Anban (70 ha) in Shaanxi. Palace-like architectures are present in all
three sites, occupying the central locations of the settlements. At
Dadiwan, for example, a multiroomed structure (F901; 290 m
size) was found in the center of the site (39). Ceramic remains
found in the structure include large-sized pottery storage urns, pile-
up bowls, and vessels of regularly graduated sizes. A large hearth
was located in the center of the major room. The house may have
functioned as a central place for activities of regional communities.
Compared with the sites in the middle Yangshao period, public
buildings in the late Yangshao period became bigger in size, and
they are likely to have served for ritual ceremonies and feasting, at
both local and regional levels (34). The construction of large public
buildings during the late Yangshao period implies an increased
level of social hierarchy and complexity. Competitive feasting is
likely to have been conducted by the regional elite for obtaining
high social status.
SI Materials and Methods
Field Sampling. The field sampling took place in the Jingwei Ar-
chaeological Station in Xian, China. All artifacts for this study were
curated in storage. Only new and sterile plastic bags, test tubes,
pipettes, toothbrushes, and razor blades were used during the
sampling process. The procedure used is as follows.
First, three residue samples for IC analysis were taken from the
interior surfaces of Funnel 1, Pot 3, and Pot 5. The residues were
yellowish in color and firmly adhering to the interior vessel walls.
Residues from each vessel were scrapped off by using a clean razor
blade. By using the same method, two control samples were obtained
from the soil adhering to the exterior surface of Pot 5 (one for IC and
one for microbotanical analysis), and one control sample was taken from
the conservation plaster material on the interior surface of Funnel 2.
Second, all artifacts were subjected to sonication. An ultrasound
bath was used to extract residues from Funnel 1, Funnel 2, Pot 1, and
a control sample (stone adze). Each artifact was placed in a new,
polyvinyl bag with 15 mL of distilled water. For Funnel 1, Funnel 2,
and Pot 1, only the mouth part (up to 2.53 cm from the opening)
was immersed in the distilled water. For the stone adze, the entire
artifact was immersed. The bag containing the artifact then was
placed into the bath for 3 min. After 3 min, the artifact was re-
moved from the bag. For artifacts that were too big to be placed in
the ultrasound bath (Pot 2, Pot 3, Pot 4, Pot 5, Pot 6, Pot7), ul-
trasonic toothbrushes were used. First, each artifact was placed in a
new polyvinyl bag. The interior surface of the artifact was then
brushed gently with an ultrasonic toothbrush and at the same time a
pipette was used to add distilled water to rinse the surface. Only a
new ultrasonic toothbrush and a new pipette were used for each
artifact. The water and all sediment from the bag were transferred
into a new 15-mL test tube. Each tube was stored in a sealed plastic
bag before laboratory analysis.
Laboratory Techniques for Starch and Phytolith Analyses. The pro-
tocol for starch and phytolith extraction is as follows:
Sample concentration. Each 15-mL tube containing sediment and
water was topped off with distilled water and placed in a centrifuge
(Eppendorf 5804, Hamburg, Germany) for 5 min at 1,500 rpm to
concentrate the sample at the bottom of the tube. The supernatant
was then decanted.
Dispersion. Fourmicrolitersof0.1%EDTA(Na
solution was added to each tube. Then the capped tubes were
placed in an automatic shaker for 2 h to disperse the sediments.
After being removed from the shaker, the tubes were filled to 15 mL
with distilled water and centrifuged for 5 min at 1,500 rpm, and the
supernatant was decanted.
Heavy liquid separation. Four microliters of heavy liquid sodium
polytungstate at a specific gravity of 2.35 was added to the tubes. The
tubes were then centrifuged for 15 min at 1,000 rpm. The top 1- to
2-mm layer of organics was carefully removed from each test tube by
a new pipette and then transferred into a new 15-mL tube. The
samples were topped off with distilled water and centrifuged for 5 min
at 1,500 rpm to concentrate the starchandphytolithatthebottomof
the tube, and the supernatant was decanted. The rinse was repeated
two more times to remove any remaining sodium polytungstate.
Slide mounts and microscope scanning. An aliquot of residue sample
was extracted with a pipette to a microscope slide and allowed to
dry. Then the residue was resuspended in 3040 μL of 50% (vol/vol)
glycerol and 50% (vol/vol) distilled water. A coverslip was placed
on top, and the edges were sealed with nail polish. All slides were
scanned under a Zeiss Axio Scope A1 fitted with polarizing filters
and DIC optics, at 200×and 400×for both starch and phytoliths.
Beer-Brewing Experiments. The brewing experiments were based on
four sets of cereal grains. The four experimental sets consisted of
broomcorn millet (40 g), foxtail millet (40 g), a mixture of broomcorn
millet (30 g) and barley (10 g), and a mixture of foxtail millet (30 g)
and barley (10 g), respectively. Each set went through three brewing
steps, including malting, mashing and fermentation. The procedure
is as follows:
First, grains were immersed in water until they began to germinate.
The room temperature was around 2028 °C. Most grains germi-
nated after 8 d, and they were drained and dried. Next, the malted
grains were crushed and mixed with heated water to achieve a final
temperature of 65 °C. The temperature was maintained for 2 h.
Finally, the mash was cooled in room temperature and allowed to
ferment in a brewing container for 2 d. During fermentation each
container was covered with a lid to create an anaerobic condition.
To obtain reference starch samples to compare with the ancient
starches, we took starch samples during the experiment. Two to
three malted seeds of broomcorn millet, foxtail millet, and barley
were taken for microscopic observation, and two patterns were
observed. First, all three types of malted grains had starches that
Wang et al. 1of8
showed pittings, channelings, or fissures radiating from their cen-
ters. The centers of the grains appeared hollowed but the outer
edges appeared undamaged (Fig. S3 AC). Second, this type of
damage was common and appeared in around 90% of broomcorn
millet and foxtail millet starches; it was rare and appeared in about
1% of barley starches. A second batch of starch samples was taken
from each set when mashing was done. Various levels of swelling
and distortion were present in 5% of broomcorn millet, and 10
15% of the other three samples (Fig. S3 D,G,J,andM). When
fermentation was finished, a third batch of starch samples was
taken from each set. Three patterns were observed from all four
brewing sets. First, pitted starch grains were still present, and their
outer edges also appeared damaged (see arrows in Fig. S3 E,H,
and K). Second, abundant starch grains exhibited swelling, distor-
tion, and loss of extinction cross. Many starch grains merged into
one another completely (Fig. S3 Fand O). Compared with mashed
samples, the fermented starch grains exhibited a higher level of
swelling and distortion; extinction cross was not observed in many
large starches. Third, some small-sized starch grains remained in-
tact (see arrow in Fig. S3L). However, we were unable to produce
quantified data from the fermented samples because a high pro-
portion of the starch grains was gelatinized and merged together.

... Recently, considerable archaeological evidence about prehistoric alcohol brewing in China has been reported based on the chemical and microfossil (starches, phytoliths, and fungi) analyses on pottery vessels, almost spanning the entire Neolithic period (Figure 1; McGovern et al., 2004;Wang et al., 2016;Liu et al., 2017a;Liu et al., 2018a;Liu et al., 2019a;Liu et al., 2019b;Liu et al., 2020a;Liu et al., 2020b;Liu et al., 2020c;Liu et al., 2020d;Feng et al., 2021;Zhao and Liu, 2021;Liu et al., 2021b). In the early Neolithic of central China, the analyses of residues from Jiahu, Guantaoyuan, and Lingkou sites have shown that globular jars were used to make cereal-based fermented beverages, and two brewing methods, including the use of malted cereal and qu starter, had already been developed and used throughout the Neolithic period (McGovern et al., 2004;Liu et al., 2019b;Liu, 2021a). ...
... In the early Neolithic of central China, the analyses of residues from Jiahu, Guantaoyuan, and Lingkou sites have shown that globular jars were used to make cereal-based fermented beverages, and two brewing methods, including the use of malted cereal and qu starter, had already been developed and used throughout the Neolithic period (McGovern et al., 2004;Liu et al., 2019b;Liu, 2021a). By the middle and late Neolithic, several archaeological studies proved that the brewing and drinking vessels in the Yangshao Culture had evolved from globular jars to flat-based jars (pingdiqi), then to conical-based jars (jiandiping) in the Weihe River valley and the western Henan, central China (Wang et al., 2016;Liu et al., 2017a;Liu et al., 2018a;Liu et al., 2019a;Liu et al., 2020a;Liu et al., 2020b;Liu et al., 2020c), while in Beixin culture in eastern China, the globular jars were still be used (Liu et al., 2020d). During the late and end Neolithic period, various pottery, including goblets and cups, were related to alcohol drinking in the Haidai region, eastern China (McGovern et al., 2005;Liu et al., 2021b). ...

Recent studies have provided evidence of alcohol production and consumption in 16 sites in northern China during the Neolithic period, focusing on the Yangshao Culture (ca. 7,000–5,000 cal. BP). Yet, the comparison of similarities and differences in brewing technology and drinking patterns within the Yangshao Culture still needs more supporting information from case studies in different regions. In this paper, 17 pottery samples excavated from the Yangshao Culture site of Qingtai (ca. 5,500–4,750 cal. BP) in the central part of Henan Province were analyzed for microfossils (starch grains, phytoliths, fungi) and organic acids, on the basis of the theoretical model constructed from our simulation experiments. The results revealed a mixed filtered alcoholic beverage, likely to be fermented by fruit and/or honey. The ingredients were mainly foxtail millet, rice, Job’s tears, Triticeae, snake gourd roots, lotus roots, legumes, nuts, fruits, and/or honey. What’s more, we found that the jiandiping amphora from Qingtai was not likely used for brewing or drinking. In terms of prehistoric drinking habits, in the large-scale settlement of the late Yangshao Culture in China, it is possible that people drank filtered alcohol alone or that a few people drank filtered alcohol poured from the painted bottle, indicating a switch from communal drinking to individual drinking. This study sheds light on the similarities and differences in brewing techniques, fermentation ingredients, and drinking patterns among different regions of the late Neolithic Yangshao Culture, and deepens our understanding of alcoholic beverages in the early Chinese civilized societies.
... Type VI: bulb of lily (Lilium spp.), occurred at all the three sites (n=6; 0.3% of the total counts; 22.2% of the total ubiquity) ( Fig. 2:11). Many species of lily are distributed in China, including Gansu and Sichuan (48:135-149), and their starches have also been found in pottery vessels from several Neolithic sites along the Wei River valley, including DDW (42,49). ...
Sino-Tibetan is the second largest language family in the world. Recent linguistic and genetic studies have traced its origin to Neolithic millet farmers in the Yellow River region of China around 8,000 y ago and also suggested that initial divergence among branches of Sino-Tibetan coincided with expansion of the Neolithic Yangshao culture to the west and southwest during the sixth millennium BP. However, archaeological investigations to date have been insufficient to understand the lifeways of these migrant Proto Sino-Tibetan speakers. Here, we present the results of the interdisciplinary research on the material culture and ritual activities related to the initial southwestward migration of Yangshao populations, based on evidence from microfossil remains on ceramics at three sites in Gansu and Sichuan, regional archaeological contexts, and ethnographic accounts of modern Gyalrong Tibetans. The first Yangshao migrants may have integrated with indigenous hunter-gatherers in the NW Sichuan highlands, and adopted broad-spectrum subsistence strategies, consisting of both millet farming and foraging for local wild resources. Meanwhile, the migrants appear to have retained important ritual traditions previously established in their Yellow River homelands. They prepared qu starter with Monascus mold and rice for brewing alcoholic beverages, which may have been consumed in communal drinking festivals associated with the performance of ritual dancing. Such ritual activities, which to some extent have survived in the skorbro-zajiu ceremonies in SW China, may have then played a central role in maintaining and reinforcing cultural identities, social values, and connections with the homelands of the Proto Sino-Tibetan migrants.

The Lower Yangtze River of China has been identified as an independent center of rice domestication, but tracing the earliest evidence for rice cultivation practices has been challenging. Here we report the first evidence for rice harvesting, based on use-wear and phytolith residue analyses of 52 flaked stone tools (10000–7000 BP) from the Shangshan and Hehuashan sites. The tools reflect two harvesting methods: reaping the panicles at the top and cutting the stalk near the base. Thus, our research provides a new method for investigating prehistoric cereal cultivation, and the data lend support to the evidence of rice domestication in the early Holocene. The results also show the complexity of rice harvesting strategies several millennia before the emergence of full-fledged agriculture in the Lower Yangtze.
... , m, p, r). These damages are probably consistent with the food processing(Ge et al. 2010;Wang et al. 2016).In addition, a total of 42 phytoliths are extracted from the pottery li and guan. Based on the classi cation and characteristics of phytoliths in some published literatures(Piperno 1988;Wang and Lu 1993, 2012;Wu 2008;Sun et al. 2012), more than eight phytolith types are identi ed, including the double-peaked glume cells, bulliform, η-shaped phytoliths, rectangular, bilobate, rondel, elongate echinate, acicular and smooth-elongate(Fig. 5, ...

The origins of agriculture and pottery were generally believed to contribute to the changes of human food resources and the innovations of cooking technologies in the Neolithic China. Hence, the investigations of the co-evolutions in human food resources, cooking technologies and pottery functions will provide a new perspective for understanding the ancient social developments. Here, taking the Mijiaya site as an example, we present the multiple analyses on the plant microfossils of pottery remains, the AMS ¹⁴ C dating and isotopes of animal bones, and the types and textures of potteries in comparison with those from some surrounding sites in northern China during the Late Neolithic period. The results indicate that the diets of Mijiaya peoples (ca. 3093‒1961 cal BC) were heavily reliant on the diversified crops and livestock supplemented with some gathering plants and hunting animals; meanwhile, Mijiaya peoples used a variety of ways to refine the pottery functions for the complex food processing. Moreover, the food processing also potentially promoted the development in animal husbandry, basing on their feeding strategy and eating patterns. These preliminarily suggest that the coordinated development in the food, cooking and potteries had contributed to the social complexity in the Late Neolithic China.
... The CVA scatter plot for these 56 taxa(Figure 3)shows how this method effectively helps identify unknown starch groups. We also compared starch granules from the Jiayi Cemetery sample with those from the published literatureGuan et al., 2014;Li, 2016;Li et al., 2010;Liu et al., 2019;Tao et al., 2015Tao et al., , 2020Wang et al., 2016;Wang et al., 2013;Yang & Jiang, 2010;Zhang, Dong, et al., 2017)-to determine plant species possibly present in the past. ...
China’s Xinjiang Uyghur Autonomous Region has long been a vital link between Europe and eastern Asia. Xinjiang’s geographical location and natural environment have led to unique dietary habits and traditions among both the region’s modern inhabitants as well as their ancient forebears. Here, we report on the analysis of human dental residue samples unearthed from the Jiayi Cemetery, a 10th to 2nd century BCE mortuary complex located in the Turpan Basin, Xinjiang, generating ancient starch granules produced by vegetal foodstuffs. Morphological analysis of starch granules and comparative data indicate that crops of Triticeae tribe and subfamily Panicoideae comprised a large portion of the diet, while common legumes, nuts, root and tuber were also present, although in relatively smaller proportions. The discovery of these plant starch granules in archaeological context provides direct evidence of the Jiayi population’s vegetal diet and sheds light on agricultural practices during this period. With supporting evidence drawn from zooarchaeological, archaeobotanical, and paleo‐isotopic studies of Bronze Age sites in Xinjiang, we conclude that the people interred in the Jiayi Cemetery practiced cereal crop cultivation and animal husbandry in the Late Bronze and Early Iron Ages. The species of cereal crops represented suggest meaningful economic communication between Central and West Asia.
... Since the 2000s, research has focused on the utilization of starch granules to determine tool functions (e.g., Yang et al., 2009;Liu et al., 2010;Shibutani, 2014), identification of plant domestication (e.g., Yang et al., 2012Yang et al., , 2015Liu et al., 2015), and human exploitation and production of plant food (e.g., Wong et al., 2011;Shibutani, 2017;Liu et al., 2018). Although the utilization of starch granules as an indicator of plant food cooked in pottery has been less reported than that of stone tool residues, these reports have focused on cooking with pottery in the early years (e.g., Shoda et al., 2011;Shibutani, 2014;Yang et al., 2014) and beer production (Wang et al., 2016;Liu et al., 2020). The functional analysis of wooden tools has been performed less frequently within and around East Asia; however, in recent years, starch residue analysis has been attempted using ethnographic tools (e.g., Kamijo, 2014). ...

This study examined starch granules from the dental calculus of specimens from the Epi-Jomon (Zoku-Jomon in Japanese, ca. 350 BCE–350 CE) period in Japan for taxonomic identification of plant food items and the reconstruction of human socioeconomic practices. Dental calculus was extracted from 21 individuals across six Epi-Jomon sites in Hokkaido. Moreover, 12 starch granules and starch clusters were recovered from nine individuals. The morphologies of the extracted starch granules were then classified into five types: elliptical, angular circular, polygonal, pentagonal, and damaged. Morphometric analysis indicated that a small portion of these starch granules may have derived from acorns, nuts, and bulb or tuber plants, with one starch granule supposedly from rice. Although extracted starch granules are poor predictors of food diversity at the individual level, the results can identify potential food sources of the surveyed population. This is the first study to determine how well plant microremains in dental calculus reflect a plant diet in the Epi-Jomon population. The starch granules discovered at the surveyed sites provide essential information about the utilization of plant species and cultural contacts in Hokkaido during this period. This is of great significance in reconstructing the Epi-Jomon subsistence patterns in Hokkaido and exploring cultural interactions between hunting-gathering-fishing and agrarian societies.
... Adlay in food and fermentation has broad prospects and a long history, such as in beer brewing recipes that are over 5000 years old, lipophilic nutraceuticals, fermented foods, and functional foods. Pottery vessels from the Mijiaya site revealed a surprising beer recipe fermented about 5000 years ago with broom corn millet, barley, adlay seed tears, and tubers [145]. Seyoeum (adlay, rice, sesame, soybeans, Chinese yam, and Liriope platyphylla) may be a functional meal replacement with anti-obesity and anti-insulin resistance effects [146]. ...

Medicinal and food homologous adlay (Coix lachryma-jobi L. var. ma-yuen Stapf) plays an important role in natural products promoting human health. We demonstrated the systematic actional mechanism of functional ingredients in adlay to promote human health, based on the PubMed, CNKI, Google, and ISI Web of Science databases from 1988 to 2022. Adlay and its extracts are rich in 30 ingredients with more than 20 health effects based on human and animal or cell cultures: they are anti-cancer, anti-inflammation, anti-obesity, liver protective, anti-virus, gastroprotective, cardiovascular protective, anti-hypertension, heart disease preventive, melanogenesis inhibiting, anti-allergy, endocrine regulating, anti-diabetes, anti-cachexia, osteoporosis preventive, analgesic, neuroprotecting, suitable for the treatment of gout arthritis, life extending, anti-fungi, and detoxifying effects. Function components with anti-oxidants are rich in adlay. These results support the notion that adlay seeds may be one of the best functional foods and further reveal the action mechanism of six major functional ingredients (oils, polysaccharides, phenols, phytosterols, coixol, and resistant starch) for combating diseases. This review paper not only reveals the action mechanisms of adding adlay to the diet to overcome 17 human diseases, but also provides a scientific basis for the development of functional foods and drugs for the treatment of human diseases.
Feasting and the drinking of beer by the Gamo Boreda, who live in the highlands of southern Ethiopia, represent status and seniority and have a long tradition of connecting the living with their ancestors. This paper focuses on the archaeological site of Ochollo Mulato (AD 1270–1950), incorporating oral traditions in association with ceramic ethnoarchaeological and archaeological research documenting the importance of beer and feasting to the Gamo Boreda. Elders recount, from their oral tradition, that Ochollo Mulato is the oldest and most senior of the nine original settlements encompassing the Gamo highlands. Oral tradition and archaeological and ethnoarchaeological ceramic analyses suggest that large-scale ritual feasting of beer and other foods were part of the activities that occurred at Ochollo Mulato over the last eight centuries.
In this article, some ingenious strategies based on chemometrics were proposed to achieve the authentication of industry and craft beers in the Chinese market. Excitation-emission matrix fluorescence spectroscopy technique was used to obtain high-dimensional data of beer samples with 3 dilution levels (the content of beer in water=3%, 50% and 100%). Alternating trilinear decomposition (ATLD) and alternating quadrilinear decomposition (AQLD) algorithms were used to characterize beer samples. Three chemical pattern recognition methods including partial least squares-discrimination analysis (PLS-DA), principal component analysis-linear discriminant analysis (PCA-LDA) and random forest (RF) were used to handle two classification tasks with different aims, including the classification of industry beer and craft beer (Case 1) and the classification of industry beer and craft beers of different brands (Case 2). For case 1, the correct classification rates of the cross-validation, training set, test set and prediction set are all above 100% obtained by the classification methods based on four-way data arrays. For case 2, the results obtained by PLS-DA based on four-way data are excellent, the correct classification rates of cross-validation, training set, test set and prediction set are 90.3%, 100.0%, 100% and 88.9%, respectively. This study showed that four-way data coupled with PLS-DA could be a good choice for all beer classification tasks. The proposed method is expected to safeguard the interests of consumers and manufacturers, and it can be extended to the authentication of other beverages.
This study presents a novel approach to pottery technology of the Urnfield culture in the Middle Ebro Valley (Spain) through petrography and geochemical analyses. In the archaeological site of ‘El Morredón’, a large settlement occupied during the Late Bronze and Early Iron Age, two petrographic fabrics and two main chemical groups have been identified, with the addition of grog as a temper in all samples as the main characteristic of the assemblage. Raw material procurement and paste recipes have been defined, revealing the specific technological choices of this community, which suggest the existence of a technological group in the Middle Ebro valley. Nonetheless, further studies with this methodology in other Urnfield’s sites in the northeast of the Iberian Peninsula are still needed to validate this hypothesis. Share link:,rVDBbwxM

Morphometric analysis has proven to be an effective tool for distinguishing among phytolith assemblages produced by closely related plant taxa. Elongate dendritic epidermal phytoliths are produced in the inflorescence bracts of many cereal species. Under light microscopy, these articulated dendritic phytoliths produce wave patterns between the margins of the cells that are reported to have taxonomic significance. In this study we explore morphometric variance among the lobes of the wave patterns formed by the articulated dendritic phytoliths within selected species of cereals as a first step towards understanding the variance between species. We found that there is often significant variance in dendritic wave lobes among different accessions of a species, among the different types of inflorescence bracts of the species (glumes, lemmas and paleae), and among each bract type’s location on the inflorescence (upper, middle and lower third of inflorescence spike or panicle). We observed that shape morphometries are typically more reliable and require a smaller sample size for statistical confidence than size morphometries. We further observed that adequate samples sizes for analysis of several shape morphometries of articulated dendritic wave lobes are considerably smaller than those reported to be required for analysis of the same morphometries of individual or isolated dendritic phytoliths. To gain a preliminary sense whether there is potential for discriminating between taxa in light of the significant variance within species, we compared our data to archaeological material from the historical center of Brussels. We demonstrate that while there is considerable variance in the morphometries among accessions, bract types and inflorescence locations within each species, there may yet be potential for discriminating between cereal species in archaeological samples by the morphometries of their dendritic phytolith wave lobes. We present one possible paradigm for conducting such analysis on archaeological material.

For more than two thousand years, drinking has played a critical role in Andean societies. This collection provides a unique look at the history, ethnography, and archaeology of one of the most important traditional indigenous commodities in Andean South America--fermented plant beverages collectively known as chicha. The authors investigate how these forms of alcohol have played a huge role in maintaining gender roles, kinship bonds, ethnic identities, exchange relationships, and status hierarchies. They also consider how shifts in alcohol production, exchange, and consumption have precipitated social change. Unique among foodways studies for its extensive temporal coverage, Drink, Power, and Society in the Andes also brings together scholars from diverse theoretical, methodological, and regional perspectives. © 2009 by Justin Jennings and Brenda J.

This book studies the formation of complex societies in prehistoric China during the Neolithic and early state periods, c. 7000–1500 BC. Archaeological materials are interpreted through anthropological perspectives, using systematic analytic methods in settlement and burial patterns. Both agency and process are considered in the development of chiefdoms and in the emergence of early states in the Yellow River region. Interrelationships between factors such as mortuary practice, craft specialization, ritual activities, warfare, exchange of elite goods, climatic fluctuations, and environmental changes are emphasized. This study offers a critical evaluation of current archaeological data from Chinese sources, and argues that, although some general tendencies are noted, social changes were affected by multiple factors in no pre-determined sequence. In this most comprehensive study to date, Li Liu attempts to reconstruct developmental trajectories toward early states in Chinese civilization and discusses theoretical implications of Chinese archaeology for the understanding of social evolution.
Brewing is one of the oldest and most complex technologies in food and beverage processing. Its success depends on blending a sound understanding of the science involved with an equally clear grasp of the practicalities of production. Brewing: science and practice provides a comprehensive and authoritative guide to both of these aspects of the subject. After an initial overview of the brewing process, malts, adjuncts and enzymes are reviewed. A chapter is then devoted to water, effluents and wastes. There follows a group of chapters on the science and technology of mashing, including grist preparation. The next two chapters discuss hops, and are followed by chapters on wort boiling, clarification and aeration. Three chapters are devoted to the important topics of yeast biology, metabolism and growth. Fermentation, fermentation technologies and beer maturation are then reviewed, followed by a consideration of native African beers. After a discussion of brewhouses, the authors consider a number of safety and quality issues, including beer microbiology and the chemical and physical properties of beer, which contribute to qualities such as flavour. A final group of chapters cover packaging, storage, distribution and the retail handling of beer. Based on the authorsâ? unrivalled experience in the field, Brewing: science and practice is a standard work for the industry. © 2004 Dennis E. Briggs, Chris A. Boulton, Peter A.
