Is wine vegan?

Wine is an alcoholic beverage made from fermented grapes. Yeast consumes the sugar in the grapes and converts it to ethanol and carbon dioxide, yielding alcohol. Different grape varieties and fermentation techniques produce a vast range of styles, from dry reds to sweet whites. People often question its vegan status because traditional winemaking can involve animal-derived fining agents used to clarify and stabilize the liquid.

The vegan status of wine is not straightforward because many winemakers use fining agents such as casein (milk protein), albumin (egg whites), gelatin (animal collagen), or isinglass (fish bladder membranes) to remove particles and improve clarity. These agents are not present in the final product, but their use during processing means the wine is not vegan. However, many modern wineries now use vegan-friendly alternatives like bentonite clay, activated charcoal, or pea protein for fining.

To determine if a wine is vegan, check the label for certifications such as 'Vegan' or 'Suitable for Vegans.' Some wines also indicate 'Unfined' or 'Unfiltered,' which often means no animal products were used. If unclear, contact the producer or use online databases like Barnivore. As an alternative, many natural, organic, and biodynamic wines are vegan-friendly. Vegan wines are widely available and often labeled clearly in stores and restaurants.
