California Shenandoah Valley Winery Map The Shenandoah Valley, directly northeast of Plymouth, is primarily located in Amador County with the northern portion of the AVA extending into El Dorado County. The Shenandoah Valley is the westernmost and, therefore, the least elevated and warmest region within the Sierra Foothills. The high temperatures result in very ripe fruit and full-bodied, high alcohol wines. During he 1960’s and 1970’s most of the Shenandoah Valley’s grapes were sold to jug wine producers. And although a significant proportion of Shenandoah Valley grapes are still sold to non-resident wineries, Shenandoah Valley Zinfandel routinely receives excellent reviews and ratings.
