The winery is beautiful and is a wonderful place to go on a nice day to enjoy the scenery, its history, and to bring family. Though not a large, famous winery compared to its 'Rutherford' cousin, it produces some splendid wines which make the trip well worth it by themselves. However, the experience would only be excellent if it were rounded out by commensurately skilled and friendly staff. A standout here was Bonnie, who, despite seemingly overwhelmingly large numbers of clients to serve, managed to serve them all--as far as I could tell-- with warmth and friendliness, a big smile, and an incredible amount of enological knowledge--both about this winery, but about wines in general. She seemed excited to share this information, and her joy in wines, and not just be a server.
