Committed to producing the highest quality estate wines without compromise, St. Sup?ry Estate Winery and Vineyards is proud to be certified Napa Green Land and Napa Green Winery. With St. Sup?ry?s reputation based on its valuable Napa Valley properties, a primary goal is to support biodiversity and sustainability while continuing the founding vision of a Napa Valley chateau for generations to come. St. Sup?ry Estate Vineyards and Winery was founded in 1982. After a decade of researching properties with the advice from Napa Valley?s most respected vintners, the founding family purchased Dollarhide Ranch, over 1,530 acres of unplanted land high in the northeastern mountains which today is the source of St. Sup?ry?s distinctive estate Sauvignon Blanc and Cabernet Sauvignon wines. The diversity of Dollarhide?s terroir contributes to the successful farming of red and white Bordeaux varieties.
