The Effect of Coombsville's Climate on Wine
Why Bordeaux Varietals Thrive in Coombsville’s Climate
The average rainfall in Coombsville is about 25 inches a year. This is at the low end of the broader Napa Valley AVA. It is a region II on the UC Davis Heat Summation Scale. During the 1960s, vineyards began to be planted in the region’s moderate climate.
Bordeaux varietals, including Cabernet Sauvignon, Merlot, and Cabernet Franc, are the most planted grapes in the region. Frazier Winery’s Lupine Hill Vineyard grows about 20 acres of excellent Cabernet Sauvignon and Merlot. They make 5,000 cases of estate bottled wine a year.
Far Niente, one of Napa’s premier wineries, buys grapes from three different properties in Coombsville. John’s Creek Vineyard and Barrow Lane Vineyard are located in the eastern hills. These properties are exposed to winds from San Pablo Bay and have a climate that resembles Carneros.
