Switchback Ridge

Switchback Ridge is a small Napa Valley producer farming the Peterson family's 15-acre estate vineyard at the base of Calistoga's Palisades volcanic ridge, established commercially in 1999. The Peterson family has farmed the volcanic basalt-influenced soils on the northern edge of the Napa Valley since the late 1970s, building a reputation for exceptionally concentrated Petite Sirah, Merlot, and Cabernet Sauvignon from a site whose mineral character gives the wines a distinctive iron and graphite quality. The Peterson Family Vineyard Cabernet Sauvignon is the flagship, earning consistent 92–96-point scores and showcasing the volcanic site's concentration and structure. The Merlot from this location is unusually structured for California — more Pomerol in architecture than typical Napa Merlot — while the Petite Sirah is one of California's finest examples of the grape: inky, tannic, and extraordinarily long-lived. With 544 lots averaging $92 per bottle, Switchback Ridge occupies a solid mid-tier position with a loyal following among collectors who prize volcanic site specificity and unusual varietal depth. Production from the 15-acre estate is naturally limited — typically 2,000–3,000 cases total — contributing to consistent auction demand. The estate's unusual tri-varietal focus on Cabernet Sauvignon, Merlot, and Petite Sirah from a single volcanic parcel is unique in the Napa Valley collector market.
