Livermore Climate & Wine Production
The Effect of Climate on Livermore Valley Grape Growing
During the growing season, the climate of Livermore Valley is warm during the day and cooled by evening maritime winds. Grapes are able to ripen and develop specific varietal characteristics during the regular sunny days of the growing season. Significantly lower overnight temperatures retain acidity in the fruit. The results are wines with balanced tannins and acidity.
Because it is located near the San Francisco Bay, winters are quite warm compared to more inland locations. This moderating body of water not only cools the region during summer, it also warms temperatures during winter. Spring frost is rarely an issue for grape growers in Livermore. Rainfall ranges from about 10 to 20 inches a year and is at the higher end in the west.
Sauvignon Blanc, Semillon, and Chardonnay all do very well in Livermore Valley. Although the region has historically been known for white varietals, red varietals have recently been gaining popularity. Cabernet Sauvignon, Merlot, and Zinfandel are now extensively planted as well.
