In the second half of the 20th century, the use of chemicals increased significantly in order to control pests and diseases and produce a better harvest. The resulting environmental and health effects of this are a big concern to many. Reducing the use of chemicals, therefore, contributes to improving the health of the farmers. It also improves the vines and the greater ecosystem as well. That’s why wine sustainability. All the wines use organically farmed or certified grapes that are produced using methods—some new, some ancient—that  limit their impact on the planet.   All the wines are made by small producers using organically farmed or certified grapes.
