Technical Abstract: My research program focuses on understanding plant primary and secondary metabolites. Grape secondary metabolites, such as phenolics, have long been valuable for the organoleptic properties they impart to fruit and wine, and, more recently, for their possible health benefits. These compounds develop the appearances, flavors, and textures that directly affect consumer purchasing decisions. Thorough identification of plant metabolites remains key to discerning how cultivar selection, breeding strategies, environment, post-harvest conditions, and processing methods influence fruit and, ultimately, wine quality. Grape phenolic research highlights from previous and current canopy microclimate management projects (sunlight, temperature, vine nutrient, and early leaf removal) will be presented. These projects were conducted in collaboration with Drs. Paul Schreiner (USDA), Patricia Skinkis (OSU), Julie Tarara (USDA), Carolyn Scagel (USDA), and industry partners.
