The Jahant AVA is an American Viticultural Area located within the Lodi AVA. Most of the AVA is located within San Joaquin County, California, with a small part in Sacramento County. At 28,000 acres (11,331 ha), Jahant is the smallest of the Lodi sub-appellations. The area is known for its distinctive pink colored Rocklin-Jahant loam soil with the AVA's boundaries being delineated by the extent and reaches of the soil. This low-lying AVA is affected by its close proximity to the Mokelumne River and the Sacramento-San Joaquin River Delta which keeps the climate cool and dry.
