Organic wine is a bit of a misnomer, because the only part of the process which is actually certified is the growing of grapes - not what happens in the winery once they’re harvested. Organic vineyards are farmed without chemical fertilisers, pesticides, fungicides or herbicides, and any treatments which are applied in the growing season are regulated by an official body. The overall aim is to treat the land in a way which is good for the vineyard itself and for the planet in the long term. Organic grapes normally form the starting point for natural wine, which goes beyond the vineyard and into the winery itself.
