WineFlavor 101D: Impact of Vineyard Management Practices on Wine Composition


Thursday May 10th 2012


Freeborn Hall, UC Davis campus


The latest in our 2011-12 Wine Flavor 101series, entitled "Impacts of Vineyard Management Practices on Wine Composition" will highlight several key vineyard management strategies and how those strategies are thought to affect resultant wine composition. We'll begin with an overview of vineyard management practices, including which practices are most effective and also cost-efficient, from Dr Nick Dokoozlian, the widely-recognized authority on this topic. We'll discuss a 2011 leaf-pull trial on Sauvignon blanc that was a cooperative effort between Trinchero Family Estates and UC Davis, and taste through the results of that trial. The morning program will conclude with an update on our Zinfandel Heritage Vineyard, established in 1989, and conclude with the first public tasting of several of the clonal selections.
The afternoon program will be led by Dr Alain Deloire, Chair of the Department of Viticulture and Oenology at Stellenbosch University in South Africa. His research focuses on berry maturation and grape physiology. He will discuss 2 issues: 1) berry sugar-loading, including a tasting of wines from his research, and 2) optimal ripeness, which will also include a tasting of his research wines.
Remember: these classes are targeted specifically to wine and winegrape industry professionals and, as such, are technical in nature. The information discussed is much the same as that presented to students enrolled in the V&E program at UC Davis, and assumes the registrants have some experience with wine and winegrape chemistry. Register early as these classes have been very popular and often sell out before the event date.
