Named for a tree used by surveyors in the 19th century, this unpretentious winery produces estate-grown chardonnays and pinot noirs. In a region of high-priced pinots, Witness Tree is noteworthy for offering very drinkable bottles at around $20 (though they also produce pricier vintage select pinots that are often very good). Witness Tree is also one of the only wineries in the region producing Dolcetto and Viognier from estate-grown grapes.
