Tuolumne County is in the southern portion of the Sierra Foothills viticulture region. Vineyards are found from 1,000 to 4,000 feet in elevation. Most commercial vineyards are planted in red varietals. However, some whites can be found.
The growing season consists of warm to hot daytime temperatures with cooling at night. The rocky and dry soils challenge the vines to work hard to nurture the precious fruit. These conditions, combined with the practice of limiting production per acre, are very favorable for the production of high quality fruit for the making of premium wines.
Some of the earliest vineyards in California can be traced to the foothills on the western slope of the Sierra Nevada Mountains where wineries sprung up in the middle 1800s.
There are seven commercial vineyards in Tuolumne County. They are as follows:
La Bella Rosa Vineyard – Old Wards Ferry Rd.
Gianelli Vineyards – Algerine Rd.
Griffin Vineyards – Potato Ranch Rd.
Larson Vineyards (Flying Star Ranch) – La Grange Rd.
Oaks Family Vineyard – Avenida Del Sol
Mt. Brow Winery and Vineyard – Mt. Brow Rd.
