Set in an idyllic valley southwest of Eugene, this is one of the largest and most impressive wineries in the state. The winery, part of a 1,000-acre estate, is surrounded by hundreds of acres of certified organic vineyards and features a huge, châteaulike facility. If you want to tour a winery, this is one of the best to visit. The winery also has a restaurant, so if you're out this way wine tasting, plan to stay for lunch or dinner.
