Switchback Ridge is in Calistoga. The 100-acre property near Dutch Henry Canyon has been in the Peterson Family since the early 20th century, though for much of that time it was primarily a farm and plum orchard. That changed in 1990 when the orchards were replanted to vineyards. Today there are nearly 18 acres planted to Cabernet Sauvignon, Merlot and Petite Sirah. The estate is owned and operated by John and Joyce Peterson, and the winemaker is Robert Foley, who is well-known in Napa Valley for he has made wine for Pride Mountain Vineyards as well as his own label. Switchback is known for its Cabs and Merlots, and the estate’s wines have earned high compliments from Wine Advocate and Wine Spectator.
