In 1982, Peter Michael Winery was established by Sir Peter Michael and Lady Michael with the purchase of 630 acres of volcanic ridges on the western slopes of Mount St. Helena in the Knights Valley AVA of Sonoma County. Drawing inspiration from the great wineries of Burgundy and Bordeaux, the winemaking team crafts terroir-driven, estate-grown wines. Today, second-generation Paul Michael and his wife Emily continue the vision, adhering to the founding principles of mountain vineyards, classical winemaking, and limited production.
