Vinegar is fermented plant material, so it is vegan. The only footnote is wine and cider vinegars made from drinks that were fined with isinglass or gelatin.
What it isA double fermentation of a plant liquid: sugars to alcohol, alcohol to acetic acid
The footnoteWine and cider vinegars inherit any fining agent used on the parent drink
Always fineWhite, malt, rice, and most balsamic vinegars
VerdictUsually vegan
Where it hides
Red and white wine vinegar, from wine that may have been fined
Sherry vinegar, same question
Some traditional cider vinegars
Balsamic, which is grape must and usually unfined
Honey vinegar, an actual exception made from honey
Dressings and condiments, where the vinegar itself is rarely the issue
How vinegar is made
Vinegar is what happens when you let alcohol keep fermenting. Yeast turns a plant sugar into alcohol, then acetic acid bacteria turn that alcohol into acetic acid, which is the sharpness you taste. Grapes, apples, rice, malted barley and plain distilled alcohol all work as a starting point.
Primary source 01 / 01
Many types of vinegar are made, depending on source materials.
Wikipedia contributorsWikipedia, quoted for its plain description of the ingredientVinegar, 2026
Every one of those source materials is a plant, and both fermentations are performed by yeast and bacteria, neither of which is an animal. That makes vinegar itself vegan without qualification.
The wine vinegar footnote
The one place a question survives is inherited. Wine and cider are often clarified before bottling with fining agents, and some of those agents are animal-derived: isinglass from fish swim bladders, gelatin, egg white, or casein. A vinegar made from an already-fined wine carries that history, even though no fining agent remains in the finished liquid. Our page on wine covers this in full. Most vegans treat filtered-out processing aids as a matter of personal strictness rather than a bright line, and vegan-certified wine vinegars are easy to find if you would rather not decide.
The one real exception
Honey vinegar is exactly what it sounds like: vinegar fermented from honey rather than fruit or grain. It is uncommon, it is labelled plainly, and it is not vegan. Beyond that, the vinegar aisle is one of the safest in the shop.
WineWine is grapes, but the way it is clarified is the catch. Many bottles are fined with fish, egg, milk or gelatin, others with clay or plant protein, and the label almost never tells you which.
IsinglassIsinglass is fish. It is a collagen made from dried swim bladders and used to clarify some beers and wines, which is why a plain-looking pint can fail the vegan test.
GelatinGelatin is boiled animal collagen, usually from pig or cow skin and bone. There is no plant version; the plant swaps are agar, pectin and carrageenan.
HoneyHoney is made by bees, and bees are animals, so honey is not vegan. Maple syrup, agave and date syrup are the usual swaps.
Frequently asked
Is vinegar vegan?
Yes. Vinegar is made by fermenting plant material twice, first into alcohol and then into acetic acid, with no animal product involved. The exceptions are honey vinegar and, indirectly, wine vinegars made from fined wine.
Is balsamic vinegar vegan?
Yes. Balsamic is made from cooked grape must and is not normally fined with animal products. Some cheaper balsamic vinegars are blended with wine vinegar, which brings the fining question with them.
Is apple cider vinegar vegan?
Yes. It is fermented apple juice. The only caveat is that some ciders are fined with gelatin before being turned into vinegar, so vegan-certified brands are the safe choice if that matters to you.
Why would wine vinegar not be vegan?
Not because of the vinegar, but because of the wine it came from. Wine is often clarified with isinglass, gelatin, egg white or casein, and a vinegar made from that wine inherits the process even though none of the agent remains.
Is white vinegar vegan?
Yes, without qualification. Distilled white vinegar is made from fermented grain alcohol and involves no fining agents or animal products at any stage.
