Promise was founded in 2004 by Jennifer and Steve McPherson. The newly-married couple bought grapes from Rich Frank, a friend and the owner of Frank Family Vineyards. The McPhersons make a Cabernet Sauvignon that is sometimes blended with Cabernet Franc and Petite Verdot. Robert M. Parker Jr. has rated Promise vintages in the mid to high-90s and called the 2007 Promise “a profound Cabernet…Absolutely spectacular…It looks to me like a classic from Napa Valley." Promise also produces Pinot Noir and a rosé. The wines are generally only available through mailing list allocations.
