Sunstone produces wines from California's Central Coast, a region defined by its maritime influence and diverse microclimates. The winery's portfolio centers on Rhône and Bordeaux varieties, with Shiraz/Syrah as a recurring anchor across its top expressions. Fred's Red, a Shiraz, leads the lineup and has drawn assessment from Wine Enthusiast, Wine Advocate, Wine Spectator, Decanter, and Falstaff. The Villa Reserve—a blend of Merlot, Cabernet Franc, and Shiraz/Syrah—and Villa Sole, which combines Cabernet Franc, Merlot, and Shiraz/Syrah, round out the core range. Both reflect the winery's commitment to blended wines that marry structure with the ripe fruit character typical of Central Coast viticulture.
