Chateau Ste. Michelle is Washington State’s founding and largest winery, with roots dating to 1934 and its historic chateau located in Woodinville, near Seattle, while its vineyards lie east of the Cascades in the warm, dry Columbia Valley. It’s best known as one of the world’s largest producers of Riesling — the flagship Columbia Valley Riesling is a perennial value, balancing ripe peach and citrus fruit with crisp acidity and a hint of sweetness, and the winery also partners with Germany’s Ernst Loosen on the acclaimed Eroica Riesling.
