Petroni Vineyards is a tuscan-style boutique winery in the beautiful Sonoma Mayacamas mountains. The wines are estate grown. The winery produces organic olive oil and grappa. We have opened our 19,000 SF wine cave and provide a wonderful, luxury tasting experience. All tastings are by appointment and are one on one with a Wine Educator. Our estate is the perfect setting for larger events (personal or business).
