Our TERROIR

The Terroir of the Pacific Northwest

Terroir encompasses a distinct combination of climate, soil, topography. Our region has a unique history of how the terroir was developed. The lava flows, floods, winds and soils. The region is rich with volcanic history and almost the entire Columbia valley is covered in a Basalt foundation. Thousands of years ago the ice shelf broke which caused the Missoula floods to wash through the region, depositing nutrients all over eastern Washington.

Coyote Vineyard

The major distinguishing feature of the Wahluke Slope is its uniformity in aspect, soil type, and climate. The entire appellation lies on a broad, south-facing slope with a constant, gentle grade of less than 8%. This, along with the proximity to the Columbia River, helps minimize the risk of frost, which can affect other areas of the state.
