Established in 2006 Naturally bounded by the Columbia River to the west and south, by the Saddle Mountains on the north, and on the east by the Hanford Reach National Monument. The Wahluke Slope AVA lies entirely within the established Columbia Valley appellation and is home to more than 20 vineyards and at least three wine production facilities. The 81,000 acre (32,780 hectares) region features approximately 5,652 acres (approximately 2,100 hectares) of vineyards: nearly 15 percent of the total wine grape acreage in the state. Top grape varieties: Merlot, Syrah, Cabernet Sauvignon, Riesling, Chardonnay, and Chenin Blanc. Wahluke Slope has one of the driest, warmest climates in the state, allowing nearly complete control of vine vigor and ripening through irrigation.
