Keyes Canyon Ranches. Handcrafted. Artisan grown. Our Keyes Canyon Ranches are location in Paso Robles, 20 miles inland from the Pacific Ocean. After sunset, temperatures drop as marine fog sweeps in, lingering until dawn. These cool evening and warm days create a longer growing season, allowing grapes to ripen to perfection. We employ artisan winemaking practices such as gentle pressing and small barrel aging to craft world-class, deeply concentrated and intensely flavored wines. Estancia Zinfandel displays densely packed black raspberry, dark chocolate and cinnamon flavors followed by a long, rich finish. Alc. 13.5% by vol.
