Clos Pegase operates in Calistoga, the northernmost appellation of Napa Valley, where volcanic soils and warm days create ideal conditions for Cabernet Sauvignon and Chardonnay. The winery's Cabernet Sauvignon Tenma Vineyard Hommage has earned recognition from Wine Enthusiast, Wine Advocate, Wine Spectator, and Decanter. Its Chardonnay Mitsuko's Vineyard Hommage and Cabernet Sauvignon Graveyard Hill Vineyard similarly draw attention from the same prestige critics. Calistoga's terroir—marked by mineral-rich volcanic earth and diurnal temperature swings—shapes wines of structure and depth. The winery's focus on single-vineyard expressions reflects the region's capacity to express distinct site characteristics through these classic varieties.
