A field-based approach will be taken, using mature wine grape vineyards. Crop load will be adjusted to within, above- and below- the wine industry's standard recommendations for the cultivar and production district. All other vineyard management will follow standard practices for the cultivar and production district. Canopy and fruit microclimates will be characterized quantitatively at physiologically important stages of vine and grape berry development. At commercial maturity, fruit will be analyzed for standard maturity indices, phenolics, and other compounds associated with quality.
