From Wikipedia:

The Puget Sound AVA is an American Viticultural Area in western Washington state. It is the only AVA in the state of Washington that is located west of the Cascade Mountains.^[3]

Geography and climate

The AVA encompasses the entire Puget Sound area from the Canadian border to just south of Olympia.^[4]

Rainfall in the Puget Sound AVA ranges from 15 inches (38 cm) to 60 inches (152 cm) annually, which is similar to many European grape growing areas and the Willamette Valley AVA in Oregon. Most of that rainfall occurs in the winter time. Summers are mild, sunny and dry. Irrigation is a necessity in some of the drier locations. The AVA is suited to cool climate varieties such as Madeleine Angevine, Madeline Sylvaner, Muller-Thurgau and Siegerrebe with some clonal varieties of Pinot Noir and Pinot Gris and Chardonnay growing well in warmer locations. Many new varieties showed promise during tests at the Washington State University Mount Vernon Agricultural Research Station. Those include Regent, St. Laurent, Zweigelt, Dornfelder and Garanoir.^[5]

History

One of the earliest recorded plantings in the Puget Sound area was done in 1872 by an American Civil War veteran named Lambert Evans on Stretch Island, near modern day Allyn-Grapeview. Evan planted several varieties of Vitis labrusca there.^[6]
