About St. Stephen Vineyards

Above all else, we focus on flavor, which begins with the sun, soil, temperature, and water. The Colchagua Valley was named “World’s Best Wine Region” by Wine Enthusiast magazine. Our grapes are grown 100% organically. We use no preservatives, pesticides, fungicides, herbicides or other toxicants. We focus on sustainable agricultural methods, including reduced crop rotation, tilling, and we use well-fed drip irrigation to eliminate runoff and minimize soil erosion and water consumption. This results in a stronger vineyard, a more robust terroir, better grapes and a healthier, superior tasting wine. Our grapes are grown and harvested by hand to reduce bruising and preserve the sugar and flavor of the grapes. Our wine is naturally aged in the finest quality French oak barrels. Rigorous quality control and grape selection from the vineyard to the barrel ensures the quality and taste of the wine. Our wine-making process is artisanal, deliberate and flexible. No two vintages are ever the same. We are constantly tasting, thinking, evaluating, and adapting to coax the best possible quality from every bottle we make. We strive to create delicious, consistent, unique, and memorable wines. Our passion for organic agriculture, sustainability and the general welfare of the planet extends beyond the fences of our vineyard, our region and our country. We are a small vineyard, few in number, but we do what we can to help. Proceeds from every bottle we sell go to organizations committed to protecting our planet, expanding national parks and wildlife refuges, reducing pollution, defending our oceans, moving beyond fossil fuels, reducing plastic consumption, and slowing climate change. This is our mission. This is what we are about. We invite you to join our cause and enjoy a bottle of our wine.
