The Yakima Valley AVA was Washington's first, granted in 1983. About 17,000 acres of wine grape sit on benches above the Yakima River, from the Rattlesnake Hills down through Red Mountain. Harvest runs from September into late October. After the fruit comes off, Cabernet rows turn deep red and Chardonnay rows go a flat gold that holds for about two weeks before the first hard frost takes the leaves down. — from the studio.
