Which of the following areas is NOT a Sub AVA of Lodi?

Fair Play is not a Sub AVA of Lodi, making it the correct choice. The Lodi AVA, located in California's San Joaquin Valley, is known for its diverse wine production and encompasses several Sub AVAs that have distinct characteristics and qualities.

Sloughouse, Jahant, and Borden Ranch are all recognized Sub AVAs within the Lodi region, each featuring unique soil types, climates, and grape varieties that contribute to the area's viticultural reputation. In contrast, Fair Play is actually located in the Sierra Foothills AVA, which is separate from Lodi and known for its elevation and varied climate, supporting different types of wine production. Recognizing the distinction between these AVAs is crucial for understanding California's wine classification and regional characteristics.
