Mount Si

Mount Si draws from the Wahluke Slope, a high-desert vineyard region within Washington's Columbia Valley known for intense sunlight and well-drained soils that concentrate fruit flavors in red wines. The winery's portfolio centers on Bordeaux and Rhône varieties suited to the region's continental climate. The Arianses Vineyard Merlot, rated 88 by Wine Enthusiast, anchors the lineup with the structured depth characteristic of Washington Merlot. A Cabernet Sauvignon (87 rating) and Lonesome Springs Ranch Malbec (86 rating) round out a focused selection of dark-fruit-driven reds. Each wine reflects the Slope's terroir—a landscape of volcanic soils and temperature swings that favor bold, age-worthy expressions.
