Go Organic!
Organic wine is made with grapes that are certified organic, free from pesticides and herbicides and GMO yeasts.
Organic wine is generally lower in sulfites and chemical additives, made with wild, natural yeasts that are different than added yeasts because they're derived from the skins of grapes.
Sulfites are naturally present in the skin of grapes, so all wines will contain at least some, but organic wine however, will contain less or no added sulfites at all.
