Are all organic wines vegan?

Although organic wines are made of grapes that are grown without the use of synthetic chemicals, not all of them are vegan. During this day there are still some winemakers that may use classic fining agents like gelatin, egg whites, or isinglass, which is derived from fish bladders in order to clarify the wine. Nonetheless, many organic wineries prefer plant-based substitutes in the form of bentonite clay or pea protein to make their wines vegan friendly.
