1: Phenolics in the Vineyard

Dr Federico Casassa

Associate Professor of Enology | Wine Sensory Analysis Wine & Viticulture Department | Cal Poly San Luis Obispo


Chemical effects of regulated deficit irrigation in fruit and wines

Dr. Federico Casassa received a BS in Viticulture and a MS in Enology from the School of Agronomic Sciences in Mendoza (Argentina), and a Ph.D. in Wine Chemistry and Sensory Analysis from Washington State University (USA). He is an Associate Professor of Enology with the Wine and Viticulture Department of Cal Poly San Luis Obispo, California. His past published research includes studies on the effect of Regulated Deficit Irrigation (RDI) and intrinsic variations of berry size in grapes and wines, cluster thinning, as well as on the various aspects of phenolic extraction and sensory outcomes of different maceration techniques in red wines. Federico has been awarded the “Best Paper of the Year Award” of the American Journal of Enology and Viticulture (AJEV) in two opportunities: 2014 and 2017. He has completed 21 vintages as winemaker in very diverse regions such as Mendoza (Argentina), France (Cotes du Rhone), and USA (Washington State and California). He serves in the Board of Directors of the American Society for Enology and Viticulture, and regularly judges for local and international wine competitions.

Dr Dylan Grigg

University of Adelaide


While vine age can influence phenolic profiles, the environment too should not be ignored

Dylan Grigg is a part time post-doctoral research fellow at the University of Adelaide in the viticulture laboratory with Dr Cassandra Collins. The remainder of his time is occupied as an independent viticultural consultant working across a number of states and regions in Australia and Europe. He has worked in the wine industry in a range of roles in vineyard management, research and consulting both locally and abroad. Dylan returned from industry to complete his PhD investigating the role of vine age on various aspects of vine growth and wine quality in both grapes and wine

Jason Smith (Presenting for Ms Julia Gouot)

Charles Sturt University


An understanding of berry temperature thresholds you really want to avoid, and the implications for phenolic composition as you approach them.

Ms Julia Gouot received her education in France and graduated with a Diplome National d'Oenologue, a Diplome d’Ingenieur Agronome from École Nationale Supérieure Agronomique de Toulouse (ENSAT) and a research Master in analytical chemistry/chemometrics from AgroParisTech (France). She first joined the NWGIC (National Wine and Grape Industry Centre, Australia) in 2015 to complete her 6-month Master internship with Dr Celia Barril, Dr Jason Smith and Dr Bruno Holzapfel. In 2016, she was awarded a scholarship from Charles Sturt University and completed her PhD with the same supervision team on the effect of high temperature on Shiraz grape tannin composition. Julia returned has returned France to take up a post-doc position with the Institute of Vine and Wine Science (ISVV), and with a busy vintage schedule her work will be presented today by Jason Smith. Dr Smith is a Senior Research Fellow in viticulture with the NWGIC and based at the Orange campus of Charles Sturt University.
