Lake County was formed in 1861 from parts of Napa and Mendocino counties,[8] but the area had European-American settlers from at least the 1840s. Lake County has long been known as a farming community.

The 1911 California Blue Book lists the major crops as Bartlett pears and beans. Other crops include grain, alfalfa, hay, prunes, peaches, apples, grapes and walnuts. Stockraising included goats, hogs, turkeys and dairying.[9]

The number of wineries also continues to grow, with over 35 wineries now located in Lake County.[12]
