Although this is one of California's best-known sparkling-wine producers, enjoying the bubbly from the light-filled tasting room—available in either single flutes or by the flight—isn't the only reason to visit Mumm. An excellent gallery displays 30 Ansel Adams prints and presents temporary exhibits by local photographers. You can even take that glass of crisp Brut Rosé with you as you wander. For a leisurely tasting of library wines while seated on the Oak Terrace
($40), reserve in advance.
