Often, but not reliably. Wine is grapes, yeast and sulphites — no animal ingredients. The issue is fining agents used to clarify it, several of which are animal-derived, and which don’t appear on Canadian labels.
Why wine needs fining
Young wine is cloudy and contains suspended proteins, tannins and particles that cause haze or harshness.
Fining agents bind to those compounds and drop them out of suspension. The agent is then filtered off before bottling, which is why it isn’t considered an ingredient of the finished wine.
The animal-derived agents
Egg albumin. Egg white, traditionally used to soften tannins in red wine.
Casein. Milk protein, traditionally used on whites to correct colour and remove bitterness.
Isinglass. From fish swim bladders, used on whites for clarity.
Gelatin. From animal collagen, used across both.
Chitosan. Usually from shellfish, though fungal versions exist.
The alternatives
Well established and widely used:
Bentonite clay. The most common plant-free option, standard for protein stabilization in whites.
Pea protein and potato protein. Increasingly used as direct replacements for casein and gelatin.
Silica gel, PVPP, activated carbon from plant sources.
No fining at all. Many producers now bottle unfined, unfiltered wine deliberately — some cloudiness, fuller texture.
The labelling gap
In Canada, alcoholic beverages are largely exempt from the ingredient labelling requirements that apply to food. There’s typically no ingredient list on a wine bottle to read.
Even where ingredients are listed, fining agents wouldn’t appear — they’re removed before bottling.
One useful exception. EU rules require that egg- and milk-derived fining agents be declared as allergens on wine labels where residues may remain. So a European import saying “contains egg” or “contains milk” is telling you something a Canadian bottle wouldn’t. The absence of such a statement isn’t a guarantee, but its presence is a clear signal.
What correlates, loosely
Unfined and unfiltered wines are a reliable indicator — if it says so on the bottle, no fining agent was used.
Natural wine generally involves minimal intervention, which usually means no animal fining. Not a guarantee, since the term isn’t regulated.
Organic and biodynamic wine is about farming, not fining. Many are vegan, but organic certification doesn’t address the question directly.
Large-scale commercial wine increasingly uses bentonite and plant proteins for cost and consistency reasons, so the animal-derived agents are less common than they once were.
How to check
Look for a vegan mark or statement. A growing number of producers label voluntarily — it’s cheap signalling and they know the market.
Check for “unfined” or “unfiltered” on the back label.
Barnivore is a long-running crowd-sourced database of vegan wine, beer and spirits. Accuracy varies since it isn’t a certification body, but it’s comprehensive and frequently cites direct producer responses.
Ask the producer or importer. Most answer, and for wine the answer is usually straightforward because the winemaker knows exactly what was used.
Ask at a good wine shop. Staff at independent shops often know which of their producers fine with what.
Is champagne vegan?
Same question as still wine, with one addition: some sparkling wines use isinglass or gelatin during production, and the dosage added before final corking occasionally contains non-vegan components.
What about sulphites?
Mineral, not animal-derived. Vegan.
Fining agents are among the clearest examples of animal-derived materials that never reach a label. VegeCert is a non-profit certification program for vegan and vegetarian food, supplement and personal care products — our prohibited ingredients list sets out exactly what we screen for.
