Wahluke Slope AVA

The Wahluke Slope AVA is located within Grant County, Washington and is part of the larger Columbia Valley AVA. It has one of the warmest, driest climates in the state.

The major distinguishing feature of the Wahluke Slope is its uniformity in aspect, soil type, and climate. The topsoil is deep, wind-blown sand which provides great drainage and its proximity to the Columbia River helps minimize the risk of frost, which can affect other areas of the state.

Grapes grown in this region are used by wineries throughout the Northwest. Top grape varieties include Merlot, Syrah, Cabernet Sauvignon, Riesling, Chardonnay, and Chenin Blanc, but this area is primarily known for Merlot and Cabernet Sauvignon.
