The grapes for Twomey Cellars come exclusively from the Soda Canyon Ranch in southeastern Napa Valley, where the rolling hills of volcanic soils are tightly planted with French Merlot clones selected for their low yield of small, intense berries. The shoots are trained vertically for optimal sun and air exposure. In this mild climate tempered by cool, foggy breezes, Merlot ripens slowly and develops rich black fruit character and extraordinary complexity.
