Clos Pegase is located in the northern part of the Napa Valley just off the Silverado Trail near Calistoga. Owner Jan Shrem built a successful publishing business in Japan and during this time married a Japanese woman named Mitsuko. She introduced Jan to wine and after 25 years in the publishing business he entered the enology program at the University of Bordeaux. Eventually he moved to Napa and enlisted the help of Andre Tchelistcheff, a winemaker of international renown and a seminal figure in the modern California wine industry, who guided Clos Pegase through its early years. Winemaker Richard Sowalsky embraces simplicity using natural yeasts, gentle handling and minimal filtration to produce wines of understated elegance. Clos Pegase owns and manages more than 450 acres in the Napa Valley, with 286 planted to grapes. One third of the grapes produced are sold to other wineries, including Acacia, Duckhorn, and Schramsberg.
