Our inaugural Letterhead release offers a true expression of a singular place and variety—Napa Cabernet Sauvignon. Our 2018 release source is a world-class vineyard in Calistoga at the base of Diamond Mountain, a location with a storied past and proximity to some of Napa Valley’s most legendary producers. It’s a unique slice of land, where the Mayacamas and Vaca Mountains practically touch in the narrowest part of the Valley. Vines here are rooted in gravelly loam soils, rich in volcanic deposits interspersed with the well-draining alluvial fans of ancient riverbeds. Here, the grapes capture a unique snapshot of Napa terroir—combining rich flavors and structural opulence for a wine to enjoy now or in 35 years.
