Alder Ridge operates in Washington's Columbia Valley, a region defined by its continental climate and deep alluvial soils—conditions that favor bold red wines with structure and depth. The winery's Cabernet Sauvignon draws on the valley's signature character: ripe dark fruit, firm tannins, and the mineral backbone that distinguishes Columbia Valley fruit. Wine Enthusiast and Wine Advocate have both assessed the winery's output, reflecting the caliber of its core offering. The Cabernet represents the winery's focus on a varietal that thrives in the region's warm days and cool nights, where diurnal temperature swings concentrate flavor and preserve acidity.
