The 2018 Complant Cabernet Sauvignon is their second vintage from the breathtaking Beller Vineyard on Mt Veeder in the Napa Valley. It is a co-fermentation of Cabernet Sauvignon and Petit Verdot. Co-fermentation is a technique that creates a synergy between the color, aromatics and structure of two varieties. One cannot achieve the same alchemy with simple blending.
