San Joaquin Valley
The San Joaquin Valley is California's major grape growing region. The valley produces a large volume of the state's wine. In fact, a bottle labeled 'California Wine' is more than 70% likely to have originated in the San Joaquin Valley. The climate ranges from region III to V and produces a large tonnage of table and raisin grapes as well as those for wine. The San Joaquin Valley makes up a huge portion of inland California south of Sacremento bordered by the Tehachapi Mountains, Sierra Nevada, and coastal mountain ranges.
