Is Wine Vegan? How Isinglass, Gelatin, and Egg Whites End Up in Your Glass

The same question applies to beer, cider, and some spirits. The ingredients on the bottle, when there is an ingredient list at all, rarely tell the full story, because the animal products involved are usually processing aids rather than ingredients. This guide explains what fining is, which agents are used, how to read the limited label information available, and how to order a vegan drink at a bar.

What is fining, and why do winemakers do it?

Young wine naturally contains tiny particles: proteins, tannins, yeast cells, and other compounds. Given time, many of them settle out on their own. Fining speeds that up. The winemaker adds a substance that attracts the particles, they clump together and sink, and the clear wine is drawn off above them.

Fining is used to:

• Make wine clear and bright rather than hazy.
• Soften harsh tannins in red wines.
• Remove proteins that could cause white wine to turn cloudy later.
• Adjust color or reduce bitterness.

The fining agent is removed along with the sediment, and only traces, if any, remain. That is why many regulations treat fining agents as processing aids rather than ingredients. For vegans, the concern is not mainly what is left in the glass. It is that an animal product was used to make the drink.

The fining agents, animal and vegan

Some winemakers skip fining entirely and let time do the work. Bottles labeled “unfined” or “unfined and unfiltered” have not been clarified with any agent, which makes them vegan in terms of processing, though you should still check for any added ingredients.

Reading a wine label for vegan clues

Wine labeling is limited compared with food, so you are looking for positive signals rather than scanning a full ingredient list.

• Vegan certification or wording. A vegan trademark, “suitable for vegans,” or “vegan-friendly” on the back label is the clearest signal.
• “Unfined” or “unfiltered.” Unfined is the important word; unfiltered alone says nothing about fining.
• Named vegan fining agents. Some producers note “fined with bentonite” or “pea protein.”
• Allergen statements in the EU. Wines sold in the EU made with egg- or milk-based fining agents must declare those allergens when residues are detectable, for example “contains egg” or “contains milk.” Newer EU wines also carry ingredient and nutrition information, sometimes via a QR code, but processing aids that do not remain are not always shown, so absence is not proof.
• US labels. Wine sold in the US generally does not have to list ingredients or fining agents, so the label usually will not tell you. Check the producer’s website or contact them.

Barnivore (barnivore.com) is a long-running, community-maintained directory of wine, beer, and spirits producers and their answers about vegan status. It is a helpful first check, with the same caveat as any list: practices change, so recent confirmation from the producer is best.

Is beer vegan?

The core ingredients of beer, water, malted grain, hops, and yeast, are all vegan. Whether a particular beer is vegan depends on clarification methods and any added ingredients.

What to watch for in beer

• Isinglass: Traditionally used to clear cask-conditioned ales, especially in British brewing. Many modern breweries have switched to other methods, but it is still in use.
• Gelatin: Used by some brewers, including home and craft brewers, to clear beer.
• Lactose: Milk sugar that adds body and sweetness. Found in milk stouts, sweet stouts, and many “milkshake” or pastry-style IPAs and sours.
• Honey: In honey ales and braggots. Mead is fermented honey and is not vegan.
• Other additions: Some specialty stouts have used oysters, and some sour or dessert beers include dairy or egg-based ingredients. Read the description.

Many beers are clarified by filtration, centrifuging, or simply time, none of which involves animal products. Unfined, hazy, or bottle-conditioned beers can be good candidates, though “hazy” is not a guarantee, since some hazy styles include lactose.

Cider, spirits, and liqueurs

Does it matter if the fining agent is removed?

Fining agents are designed to settle out with the sediment, and much or all of them is removed before bottling. So a common question is whether a wine fined with egg white or isinglass is “really” non-vegan if little or nothing remains.

Most vegans and vegan certification schemes say yes, it still counts, for the same reason bone char sugar is debated: the animal product was used to make the drink, and the demand for it comes from that use. Others see trace processing aids as a lower priority than the foods they eat every day, and focus their energy there. Both positions exist among thoughtful vegans. What matters most is that you know the facts and choose a standard you can keep consistently.

For anyone with an egg, milk, fish, or shellfish allergy, the question is different. Residues can occasionally remain, which is why EU rules require egg and milk to be declared when detectable. If you have an allergy, speak with your allergist about wine and beer.

Ordering vegan drinks at a bar

Cocktails introduce ingredients that bottles do not. The common ones:

• Egg white in sours, fizzes, and flips. Ask for aquafaba if the bar keeps it, or order the drink without foam.
• Honey syrup in drinks like the Bee’s Knees and many modern cocktails. Ask for simple syrup, agave, or maple instead.
• Cream and milk in drinks like a White Russian. Ask whether the bar has oat or another plant milk.
• Worcestershire sauce in a Bloody Mary or Caesar, which typically contains anchovies. Ask them to leave it out or use a vegan alternative.
• Clam juice in a Caesar cocktail.

For house wine and beer, a simple question works: “Do you know if any of your wines or beers are vegan, meaning not fined with egg, gelatin, or fish?” Staff at wine-focused places often know. If not, choosing an unfined wine or a spirit with a simple mixer is a reliable fallback. Our guide to restaurant questions that get better answers covers the same approach for food.

Making vegan drinks at home

At home, you control everything. Aquafaba is the standout swap: the liquid from a can of chickpeas whips and foams much like egg white. For a single sour, shake about three quarters of an ounce of aquafaba with the other ingredients without ice first, then again with ice. Replace honey syrup with a one-to-one mix of maple syrup or agave and warm water. For creamy drinks, oat and cashew milks hold up best; see the best plant milks for cooking and coffee. If you have a favorite drink or punch recipe that calls for egg, honey, or cream, paste it into Veganize This for a plant-based version.

If you are hosting, a bottle of certified vegan wine or a batch cocktail made with aquafaba lets everyone drink the same thing. Pair it with something easy to share, like garlic herb mushroom bruschetta. For bigger events, planning an entirely vegan event includes drinks.

Your next step

Before your next wine or beer purchase, look up two or three producers you already like in a vegan drinks database, then confirm with the producer’s website if the entry is old. Keep a short note on your phone of the bottles that check out. At bars, default to asking about egg white, honey, cream, and Worcestershire, and you will cover almost every cocktail. For food labels, the same logic is laid out in how to read a food label when you are vegan.
