Washington's high-quality premium wines have earned the state international recognition, critical acclaim and legions of loyal consumers. It's a winning combination that translates into success in the marketplace.

The Columbia Valley
Washington's success with vinifera grapes is due in large measure to the state's unique geography. The vineyards are planted on the east side of the Cascade Mountains which serve to protect the region from marine weather off the Pacific coast and limit rainfall to just 6-8 inches annually. Low rainfall and free-draining soils allow vineyard managers to control vine vigor in order to promote flavor development in the grapes. Warm daytime temperatures ripen fruit to perfection. Cool autumn nights protect the grapes' natural acidity.
