Diamond Creek was founded in 1968 by Al and Boots Brounstein who were pioneers of the modern Napa Valley wine industry. Back then they defied modern conventions and planted Bordeaux varietals on secluded Diamond Mountain becoming California's first exclusively Cabernet Sauvignon Estate Vineyard. Historically known for being one of the best producers in Napa Valley, in 2020 the Brounsteins found the ideal stewards for Diamond Creek and sold the vineyards to the Rouzaud family of world-renowned Maison Louis Roederer. The Rouzauds have a deep reverence for history and a generational vision for the future of their wine estates and today continue to craft a small amount of exceptional and elegant long-lived wines sourced from the four unique vineyards of Diamond Creek. Wines that are honoured and cherished by connoisseurs everywhere.
