Wine tourism is a fast-growing industry that can be particularly important to the development and sustainability of rural areas such as the Riverland wine region in South Australia. Capitalising on this growth can be quite difficult as wine regions struggle to differentiate themselves, and attract tourists due to the lack of consumer awareness of t...
Article
Authentication of wine can be considered at different scales, with classification according to country, province/state, or appellation/wine producing region. An absorbance-transmission and excitation-emission matrix (A-TEEM) technique was applied for the first time to examine intraregional differences, using Shiraz wines (n = 186) produced during t...

Understanding how wine compositional traits can be related to sensory profiles is an important and ongoing challenge. Enhancing knowledge in this area could assist producers to select practices that deliver wines of the desired style and sensory specifications. This work reports the use of spectrofluorometry in conjunction with chemometrics for pre...
Article
Body is a key sensory characteristic for beverage acceptability, drinkability and important when making a purchase decision. Evidence suggests that consumers perceive low-alcohol beverages as lacking in body. Despite the significance of body, little is known about consumer's understanding of the term. This paper employed a qualitative approach to g...
