AVA Wahluke Slope
The Wahluke Slope AVA lies in a unique position in Central Washington State anchored by the Columbia River on two sides and the Saddle Mountains to the north providing one of the driest and warmest climates in the state. This is used to an advantage in controlling the canopy and character of the fruit with drip irrigation giving grapes in this area unique complexity.
