Wine chemistry • Prof. Dennis Taylor; A/Prof. Graham Jones • Wine phenolic chemistry – tannin composition; identification of wine pigments • Synthesis of important wine flavour and aroma compounds
Wine microbiology • Dr Vladimir Jiranek: • Novel wine yeast production by directed evolution • Characterisation of microbial enzymes with importance for winemaking and brewing • Fermentation technology • Dr Paul Grbin: • Wine spoilage micro-organisms • Management of malolactic fermentations
100 ml - 1 L Ferments Facility located in cool room Pneumatic pistons raise 3 vessels to allow weighing of remaining one - automatically cycles through others Use 4 x 100 ml or one 1 L vessels Heating pad and magnetic stirrer, independent settings possible Precision balance relays weight data to PC (each 30 min) Software allows display of fermentation curves in real-time Current capacity = 64 x 100 mL vessels
Sensory Science • Dr Susan Bastian: • The physiological basis for the perception of astringency in wines • Consumer preferences and the perception of astringency in red wines • (with DT) Cyclodextrins as alternative fining agents
Grapevine pathology • Eileen Scott • Organic control of powdery mildew in grapevines • Trunk diseases in grapevines • Over-ripe fruit and microbial load
Viticultural and vine physiology • Peter Dry, Cassie Collins: • Fruitset and fruitfulness determinants • Vine water use • Steve Tyerman, Brent Kaiser, Matt Gilliham; Roger Leigh: • Water relations; aquaporins • Nutrient transport • Berry physiology
Grapevine biochemistry • Chris Ford: • Metabolism of organic acids during berry development • Role of glucosyltransferases in grapevine secondary metabolism
Wine technology • Graham Jones: • Extraction and recovery of potentially valuable compounds from winery waste • Novel wine stabilisation strategies (with Chem. Eng.) • Chris Ford: • The consquences of extended maceration in red wine composition
Wine marketing and business • Dr Johan Bruher, Dr Elton Li, Dr Karan Alant • Consumer preferences for Australian wines • Wine tourism • The cellar door experience
Research Collaborations • Waite Campus: AWRI, CSIRO, SARDI, UA • Major wineries and winery supply companies • Australian and overseas universities – e.g. UC Davis; UBC; • Wine Innovation Cluster – will build upon existing collaborations
