Founded in 2005, this AVA encompasses roughly 6,070 hectares with 37 varieties planted at largely south-facing slopes mostly set on sandy-loam soils.
The region represents 27% of Washington’s total wine production and the nearby rivers have a strong mitigating effect, as the region is bounded on the north by the Yakima Valley AVA and on the south by the Columbia River.

The proximity to the rivers creates 30% more wind while moderating temperature extremes, as this is one of Washington’s warmer sites.
Winds also lead to smaller canopy and berry sizes leading to extremely concentrated small berries at some sites as well as help to reduce frost risks which are sometimes prevalent at the start and end of the growing seasons.
