|Ferrara practices organic agriculture, but is not Certified Organic. Ferrara uses only copper and sulfur to combat mold and pests, environmentally integrating their approach to insect and disease control. Cover crops are left between the rows of vines, and after mowing, the cuttings are tilled into the soil for added fertilizer. The soil is analyzed and, if needed, only Potassium and Magnesium are added. Insects and fungus are scarce because of the dry, higher altitude of this site. Steady, light breezes work to reduce the threats of mold and other predators. The Ferrara family adds a small amount of SO2 in the wines before shipping in order to preserve their freshness and integrity.
