Summit Lake sits on Howell Mountain, where volcanic soils and elevation shape wines of structure and depth. The winery produces Cabernet Sauvignon, Zinfandel, and Petite Sirah—varieties that thrive in the mountain's intense growing conditions. The Emily Kestrel Cabernet Sauvignon anchors the portfolio, joined by a Zinfandel and the Sophia Lynn Petite Sirah. These wines have been assessed by Wine Enthusiast, Wine Advocate, Wine Spectator, and Decanter. Howell Mountain's reputation for powerful reds is rooted in its terrain: steep slopes, thin soils, and diurnal temperature swings that concentrate fruit and tannin. Summit Lake's selections reflect that character—wines built on the mountain's volcanic foundation.
