California Harvest Report: Winemakers Optimistic for 2021 Season

By Published On: November 10, 2021

With a “smooth harvest following a moderate and consistent growing season,” winemakers are predicting this year may be the best vintage in recent member for California, according to a report by the Wine Institute.

“The weather was excellent this year, with mild temperatures at the end of the growing season,” said Ted Henry of Groth Vineyards in Napa Valley, in the organization’s annual report. “We got a little more time to mature flavors before pulling the fruit off the vine. Yields were on the lighter side due to smaller clusters and berries, but otherwise, the vintage was free from significant issues. I think 2021 will be a top vintage in the Napa Valley.”

  • Amador County: 3,644 – Zinfandel and Barbera
