Exceptional 2010 Vintage Prevails Over Challenging Summer Growing Season

NAPA, Calif. (October 14, 2010) – Napa Valley Grapegrowers report that the 2010 vintage is shaping up to be of exceptional quality, despite the unruly weather that the region received.  The cooler than average summer temperatures followed by several heat spells have not distressed the grapes as predicated by some.  In fact, the long growing season is resulting in winegrapes of well-developed flavors and more balance.  The later- than-normal harvest is proving to be a quality vintage the Napa Valley Grapegrowers are proud to stand behind.

“This was, by many accounts, the most challenging growing season we’ve experienced in a long time, but what I am seeing has made me extremely optimistic about the flavors and quality of this year’s vintage,” said Ann Vawter, winemaker and proprietor at Red Mare Wines and a member of Napa Valley Grapegrowers. “These last few heat waves are helping to produce mature grapes that will help to distinguish this as a premier year for Napa Valley wines.”
Another member of the Napa Valley Grapegrowers, Jon Ruel, the director of viticulture & winemaking at Trefethen Family Vineyards, says he has seen “big changes in flavors and chemistry over the past week. The relatively higher acids this year have come down with the recent heat wave – and where it is still high, it’s mostly malic acid which can be consumed in malolactic fermentation.”

Members of the Napa Valley Grapegrowers have an extremely positive outlook on this year’s harvest.  In the Carneros region, grapegrowers are reporting good seed maturity and tremendous flavor in their harvest.  Stag’s Leap is discovering its harvest has tremendous flavor without any green characters.  At Trefethen Family Vineyards in the Oak Knoll District, they saw warm temperatures provide a nice finish to the early varieties and push the Cabernet to maturity.
