Stonetree Vineyard, Wahluke Slope AVA
On a south-facing slope of the Saddle Mountains above the Columbia River lies this 250-acre vineyard named for the site’s petrified trees. The Wahluke Slope (pronounced WAH-luke) is among Washington’s warmer sites, easily exceeding 3,200 heat units per year. Growing conditions include desert-like sunshine, only about 7.5 inches of rain annually, and soils comprised of caliche (a calcium carbonate/rock aggregate), glacial outwash, and windblown sands. Angel Vine has sourced Zinfandel, Primitivo, and Petite Sirah from this site since our 2008 vintage.
