Founded in 1984, the Walla Walla Valley became Washington’s second American Viticultural Area (AVA). Impacted by prehistoric volcanic history and the cataclysmic glacial Missoula Floods, the Walla Walla Valley has a specific set of traits – elevation, soil and climate – all factors that influence a grape’s flavor and the resulting wine’s color, aroma and structure. Our wines are a truly original experience. WALLA WALLA VALLEY AVA • ESTABLISHED 1984 •
