Mezzetta Brand Napa Valley Bistro™ All Natural Authentic Pizza Sauce. Authentic sauce made with fine wine. Since 1935. Made the traditional Italian way using wine and pure, fresh ingredients. All natural. No added sugar. No paste. Our extensive travels through Southern Italy inspired us to create this authentic pizza sauce. We start with Italian plum tomatoes from Italy's San Marzano region for an intense tomato flavor and smooth consistency. In addition to these superior tomatoes we use olive oil, sea salt, oregano and garlic. In the Italian tradition, fine wine is added to deepen and balance the flavor, and to assure quality we partner with local Napa Valley wineries. This high quality sauce will be the perfect foundation for your own inspired homemade pizzas. Try our Napa Valley Bistro Pasta Sauces. Discover great recipes and ideas at mezzetta.com.
