Certified organic. Biodynamically farmed. Fed with compost from the winery and bioreactor. super healthy. Grows around the Kenwood Marsh, buds out late due to very cool area of Sonoma Valley, harvested late. Good yield but definitely not over cropped. Cordon pruned, usually with a kicker. The vineyard is surrounded by not only the wetlands but wild blackberries, the pollen from which flavors the grapes. They have high palate dark berry flavors with less earthiness, no dirt taste. Delicious.
