Nowadays, climate change is a very important and high-priority subject worldwide
due to its significant impact on all agricultural productions and various strategic
sectors. That means that grape growers and wine producers must be attentive to these
rapid changes and their consequences. The production of grapes and grape products
is already feeling these fast changes and their important impacts, necessitating strategies
to avoid or minimize the side effects of global warming by grape growers and the
wine industry.
This book aims to provide important information about the impact of climate change
on grapes and grape product mycotoxins and on some physicochemical parameters,
such as sugar levels in grapes and grape products, dealcoholization treatments, the
production of wines with low alcohol content, and innovation in the wine industry.
Thus, the chapters of this book cover different topics related to the impact, strategies,
and treatments to minimize the effect of climate change on grapes and grapes
products.
The general impact of climate change is presented and discussed in the first introductory
chapter of this book. The fungal activities on vines and grapes are strictly
dependent on the climate and microclimate conditions during their production.
Climate change could alter fungal activity and the content of mycotoxins. Chapter
2 is a review that explores the presence of mycotoxins in grapes and grape products,
focusing on various types such as ochratoxin A, aflatoxins, fumonisins, patulin, and
others. The discussion encompasses multifaceted factors influencing mycotoxin
occurrence, including environmental aspects, agricultural practices, post-harvest
handling, and advanced techniques for mycotoxin detection. Mitigation strategies,
such as the implementation of good agricultural practices and good manufacturing
practices, are also presented and discussed.cultivation, the timing and progression of vegetation phenophases, and the overall
quality of grape production. The temperature changes recorded and their influence
on grapevine phenology and wine characteristics highlight the need for ongoing
research and proactive measures to ensure long-term sustainability and resilience of
grape cultivation in the face of climate change. These points are thoroughly explored
and discussed in Chapter 3, where the question is posed, “Grape Technology vs.
Climate Change: A Success Story or a Nightmare?
Recently, research on the adverse effects of alcohol consumption has spurred a trend
toward low-alcohol wine, typically containing less than 8.5% alcohol by volume.
This caters to health-conscious consumers and presents an economic opportunity
for winemakers in an emerging market. Despite the industry’s millennia-old history,
there remains ample room for innovation in low-alcohol winemaking. With shifting
consumer preferences and climate change, the demand for lower-alcohol wines is
poised to grow, necessitating ongoing research and innovative practices to create wellbalanced
wines. The opportunities and challenges for low-alcohol wines are interestingly
explored in Chapter 4 of this book.
Chapter 5 explores strategies to reduce the effects of global warming on sparkling
wine production. The quality and characteristics of sparkling wines, their stability,
and their sensory properties largely depend on the physicochemical composition of
the grapes and the respective base wine, the production technology applied, and the
environmental conditions. Several techniques can be implemented to produce lowalcohol
base wines, and reverse osmosis is a procedure that has been successfully used
in recent times to reduce the alcohol concentration while having a low negative impact
on the wine composition under certain conditions. This chapter looks at the effects of
reverse osmosis and the implications of inoculated yeasts on sparkling wine quality.
Finally, in the last chapter (Chapter 6), the authors explore the experimentation and
practices of innovation that can take place in the wineries at the individual level and
at different stages of wine production. The innovation processes are not radical but
tend to be entrepreneurial practices of experimentation. The chapter takes a first
glance at how practice theory can be implemented in the study of wine and entrepreneurship.
The chapter is based on qualitative interviews conducted in New South
Wales (Australia), Var (France), and Ribera del Duero and Toro (Spain).
Summing up, this book covers a wide range of issues and hot research topics about
the impact of global warming on grapes and grape products. The challenges faced
by vineyards and wine production under new climate conditions are important hot
points. This compact book provides a rapid overview of the general consequences of
climate change and explores some strategies and solutions to avoid or mitigate the
negative impact of warm temperatures on grapes and grape products. This book is
heartily recommended for graduate and Ph.D. students in enology and food science,
as well as for winemakers, viticulture specialists, winegrowers, and wine producers.
