With the reimagining of Markham Vineyards since 2018 when it celebrated its 40th Anniversary, Winemaker Kimberlee Nicholls has established a District Series, and named this wine for the blue cowboy boots she wears during harvest. She chose Calistoga for this blend of 63% Cabernet Sauvignon and 37% Merlot from the winery’s 72-acre Rockerbox Estate Vineyard. Aged 18 months in French oak with 28 days of skin contact, it imparts one of the most precious, satin-lined mouthfeels of sun-ripened black raspberry. A dot of white pepper zings on toasty oak, adding to the pureness of cherry jam and wet stone on the finish.
