Vegan wines are wines that are produced without the use of any animal-derived ingredients or processes. Traditional winemaking often involves the use of animal-derived fining agents, such as egg whites, gelatin, or isinglass (made from fish bladder), to clarify and stabilize the wine. However, in the production of vegan wines, these animal products are avoided. Vegan wines are wines that are produced without the use of any animal-derived ingredients or processes.
