In Oregon, Pinot noir comprised approximately 43 percent of the total acreage and approximately 6,800 were harvested in 2000. In previous years, Chardonnay (1,125 acres in 2000) had been the...
During the 1995 harvest season Pinot noir development during ripening was monitored at Woodhall Vineyards (WHV) in Alpine and at three commercial vineyard sites at Croft (CR) Vineyards in Monmouth, Rex Hill Kings Ridge Vineyard (RHKR) in Newberg, and Erath Vineyards (ER) in Dundee. Cluster samples (25) were taken weekly...
