Start your day with a visit to V. SATTUI WINERY in St. Helena, the heart of Napa Valley, for a guided tour of the vineyards, production facilities, barrel room, and cellar followed by a tasting. Next, drive to the town of Calistoga with time for lunch and to stroll the streets that retain their charm of yesteryear. This afternoon, learn how famous champagne-maker MUMM creates its California sparkling wine in the traditional French method at MUMM NAPA. Sample a glass of their bubbly to toast a great day!
