Western Washington is home to the Puget Sound AVA, and Washington’s maritime grape production region. Typified by mild winters and cool summers, the climate is appropriate for many cool climate Vitis vinifera wine grapes, as well as sparkling wine production.

While the Cascade Mountains provide the physical separation from the vastly different climate conditions in eastern and western Washington, general grape production principles are the same across these two regions; it is the translation of those principles into practices that can differ as dramatically as the climate.

To highlight region-specific information, certain links are emphasized with the “WESTERN WA tag. This does not mean that the other listed resources are not relevant for the region, but rather, those tat are tagged are specifically useful for western Washington growers.

For those who are growing less than two acres of vineyards, we encourage you to visit our Backyard Vineyard webpage, which has a specialized focus on small vineyards that rely predominately on hand labor.
