Vegetative Aroma: Sensory Definition, Chemical Interpretation (and ultimately) Causal Explanation

During the 2001-2002 funding year we obtained wines and associated viticultural information from industry cooperators. A graduate student was hired and has been coordinating these efforts. Sensory studies have been initiated and are expected to be completed by the end of the funding year. A GC-O-MS instrument was purchased, has been installed at UCD, and preliminary method development and validation has begun. Descriptive analysis of wines made from a wide range of Cabernet Sauvignon viticultural trials has begun. The completed analysis will act as a screening tool, identifying potentially important viticultural parameters meriting further systematic study.
