You probably have a bottle of Mumm's well-known sparking wine at home. Why not try it at the source? The valley views are spectacular and the respectable sparkling wines are sampled by the glass beneath a vineyard-side pergola or seated on a vineyard-view terrace – ideal if you want to impress conservative parents-in-law.
Dodge crowds by coming early, or paying $45 for the reserve-tasting Oak Terrace (reservations required). There's also a fabulous photography gallery featuring the work of Ansel Adams. Last seating is at 5:45pm.
