Potter Valley's Climate & Wine Production
Why the Potter Valley Climate is Suited for Pinot Noir & Chardonnay Production
Grapes from the region have concentrated flavors from the warm days and sufficient acidity from the cool nights. Because the temperature fluctuates so much, it is very to point to the dominance of any one varietal. Cool and warm weather grapes thrive in specific microclimates, which are quite diverse themselves.
That said Pinot Noir and Chardonnay are widely grown in the AVA. Warm day time temperatures develop flavors and sugars in these two varietals. Cold nights help to retain acidity and balance. Some of these grapes are sourced for sparkling wine production.
Zinfandel, Petite Sirah and Sauvignon Blanc are also right at home in parts of the AVA. Cool nights prevent too much sugar from forming in the grapes and ultimately keep alcohol levels in check. Rainfall averages about 35 to 45 inches a year.
