Three San Joaquin County-based farming companies are among the largest grape growers in the United States, according to American/Western Fruit Grower magazine.
The leading grower, with 40,000 acres of vineyards, is Bronco Wine Co. of Ceres.
But No. 2 is Lodi's Vino Farms, with 16,000 acres of vineyards under cultivation.
John Kautz Farms, also of Lodi, is No. 7 on the magazine's list with 6,500 acres of grapes under cultivation, and No. 16 is Stokes Farms of Thornton, with 4,000 acres.
An honorable mention should go to DFV Wines with 5,000 acres of vineyards, the 10th-largest grower. Now headquartered in Napa, it was founded as Delicato Family Vineyards in Manteca.
While all these leading producers have vineyards both in San Joaquin County and throughout California's other leading wine regions, their success is explained by the Lodi area's rich soils and a climate influenced by cool ocean breezes flowing in from San Francisco Bay, growers said.
