Is Wine Vegan

Young wine is cloudy with proteins, tannins, and yeast fragments. Fining removes them by adding a substance that binds the haze and settles out, taking the unwanted material with it. The agent is then filtered off.

Which agent gets used depends on what the winemaker is trying to strip. Egg white has long been favoured for softening tannin in red wine. Casein from milk is used to lighten colour in whites. Isinglass gives brilliance to whites. Gelatin removes bitterness. Each of these is animal-derived, and all of them are legally processing aids rather than ingredients.

One rule cuts through part of the fog. Since 2012 the EU has required wines fined with milk or egg proteins to declare it when residues remain detectable, which is why bottles increasingly carry contains egg or contains milk. That rule says nothing about isinglass or gelatin, so its absence settles very little.

Look for the words unfined and unfiltered on the back label. Both signal that no fining agent was involved, which answers the question outright, and natural wine producers use the terms freely.

A vegan certification mark is the other clean answer. Several supermarket ranges now flag vegan wines on the shelf edge, and specialist merchants filter by it online.

Where neither appears, Barnivore holds a large body of producer responses. Failing that, the importer is usually easier to reach than the estate and generally knows the fining regime.

Wines labelled unfined or unfiltered, natural and low-intervention wines, and anything carrying a vegan mark.

Bentonite clay, pea protein, potato protein, and activated carbon all do the same job as the animal agents, and producers who use them tend to advertise the fact.
