Founded in 1994, Hartford is a bastion of fine single-site wines from across Sonoma County. Proprietor Don Hartford is still very hands-on to this day, with winemaking overseen by Jeff Stewart and Tiaan Lordan. This extensive portfolio of single-vineyard Chardonnays, Pinot Noirs and Zinfandels (plus a few others) focuses on a diverse array of sites, all expressed through entirely native fermentations and modest use of new oak in élevage.
