About Summit Lake Vineyards & Winery
Summit Lake Vineyards & Winery is a distinguished Napa Valley winery crafting Zinfandel and Cabernet Sauvignon from select vineyard sources in the Howell Mountain appellation. Established in 1971, the project reflects a commitment to quality-driven winemaking, with production limited to ensure hands-on attention at every stage from vineyard to bottle. The wines are designed to express the distinctive terroir of their origins while remaining true to the winemaker's vision.
The winemaking at Summit Lake Vineyards & Winery emphasizes structure and age-worthiness. Cabernet Sauvignon is sourced from proven vineyard sites and crafted with careful extraction, French oak aging, and patient blending to develop layers of complexity. The Cabernet Sauvignon provides a complementary dimension, broadening the portfolio and demonstrating the range of the winemaking program. The cellar work is precise without being formulaic, allowing the natural quality of the fruit to guide the finished wine.
Summit Lake Vineyards & Winery welcomes visitors by appointment at the estate in Angwin. The experience is welcoming and educational, with flights designed to showcase the current releases and the vineyard philosophy behind them. The setting provides an authentic window into Howell Mountain winemaking.
