This slick operation is one of the most visited wineries in the valley, thanks to its prime location on Hwy. 246 and its in-depth tours, offered daily. It has every hallmark of a visitor-oriented winery: a terra-cotta-tiled tasting room, plenty of logo merchandise, and a deli case for impromptu lunches at the picnic tables in a secluded vineyard garden. It bottles the most popular varietals -- chardonnay, cabernet sauvignon, pinot noir, sauvignon blanc -- and offers them at moderate prices.
