Valentine Vineyards is a small family-run winery in Southern Mendocino County, just a quarter of a mile from the Alexander Valley appellation. The vineyard was planted in 1976 by Rodney Strong with 100% Cabernet Sauvignon. Between 1975 and 1985, the vineyard was operated by Sonoma Vineyards which produced wine from the vineyard under the designation “Haehl Ranch”. In 1987, the vineyard was purchased by Bob Valentine and became Valentine Vineyards.

Since the purchase of Valentine Vineyards, Bob Valentine has been busy at work both selling his grapes to outside wineries and producing his own private, award generating wines comprised of 100% Valentine fruit. The gold medals collected in amateur wine competitions over the past decade are both numerous and impressive. Triple gold awards are not uncommon in Bob Valentine's repitoire of amateur wine awards.
