Edna Valley Chardonnay is made with grapes grown in a coastal climate. Cool breeze and fog enters the AVA through the Los Osos Valley from Morro Bay. These climatatic features are particularly pronounced during the Summer. According the the Winkler-Amerine Climate System, the AVA is a Region II.

The growing season in Edna Valley is extremely long and can last from February to November. In comparison, it is uncommon to harvest later than October 15 in the Napa Valley. These extra few weeks on the vine can make all the difference.

The east-west oreiented valley causes fog to move into and cool the region overnight after often sunny days. The AVA is exposed to almost unobstructed marine influence from the west. Oceanic influence from nearby Morro Bay accumulates against the eastern mountains and often settles in the Edna Valley. The air is quite a bit cooler than in surrounding AVAs.

Acids in grapes are high and the long growing season allows grapes to ripen fully. Wines have distinctive varietal characteristics and balanced components.

The AVA is home to the famous Edna Valley Vineyard. Approximately 120,000 cases a year under this label. The wines are aged “sur lie” in French barrels and undergo and amount of maloactic fermentation. These wines are an extremely good value for fans of this style of Chardonnay.
