John Williams and his team at Frog’s Leap built their Rutherford Estate cabernet program on three vineyards: Red Barn (surrounding the winery), Chavez Leeds (in partnership with viticulturist Frank Leeds’s family) and the Rossi Ranch, 50 acres of prime real estate on the Rutherford Bench west of Highway 29, a property the winery purchased in 2007. This blend includes 13 percent merlot from Rossi, which fills out the wine and polishes the bitter, earthy tannins of cabernet, making this a fat, luscious vintage to serve with filet mignon.
