Clos Pegase is one of Calistoga's more distinctive winery visits, not just another tasting room among the vines. The estate was designed by postmodern architect Michael Graves for founders Jan and Mitsuko Shrem, who wanted a place where wine, architecture, gardens, and art could sit together without pretending to be an old Tuscan village.
The wines are the practical reason to book, but the building is what makes the stop memorable: theatrical colours, classical references, sculpture, and cave spaces that feel more designed than merely functional. It is a good counterpoint to the region's rustic stone cellars and faux-chateau estates. Reserve ahead, especially on weekends.
