Abstract or Summary
  • Thirty five vineyard blocks of Pinot noir were sampled at harvest by taking a two hundred cluster sample in 1993. Commercial wines from these blocks were analyzed by HPLC at two and nine months of age. Cluster weights ranged from 72 to 148 g, berry weights from 0.55 to 0.90 g, and Brix from 20.8* to 24.7% Acidulated ethanol skin extracts of a 200 to 500 berry sub-set were analyzed by HPLC for phenolic composition. Anthocyanin concentrations varied by 2 fold between the lowest and highest sample, total phenolics by 3 fold, quercetin glycosides by 5 fold, and polymeric compounds by 15 fold. Vineyards with the highest anthocyanin and quercetin concentrations were generally younger vineyards in their first to third year of production.
