Kongsgaard produces wines in Napa Valley, California's premier wine region. The winery focuses on Chardonnay, Syrah, and Bordeaux-style blends—varietals that thrive in the North Coast's temperate climate and complex soils. The Judge Chardonnay, a flagship white, demonstrates the region's capacity for richly textured, age-worthy expressions of the variety. The Fimasaurus, a Merlot-Cabernet Franc-Cabernet Sauvignon blend, and the Syrah round out a portfolio rooted in classic varietal expression. These wines have been assessed by major critics including Wine Advocate, Wine Enthusiast, Decanter, Wine Spectator, and Falstaff.
