What it is
A volcanic ash clay that binds to proteins and pulls them out of wine.
Why vegan
Mineral origin; the standard vegan alternative to isinglass and egg whites.
What a “Vegan” verdict means
A vegan verdict means the ingredient itself contains no animal-derived material and is not conventionally produced using animal inputs. It does not guarantee the finished product is vegan: the same label can carry dairy, egg or honey elsewhere in the list, and shared production lines can add 'may contain milk' warnings.
Where you'll find it
- Most modern white wines
- Vegan-certified wines

How to read the label
Bentonite Clay (Wine Fining) belongs to the alcohol and finings family. These are the terms worth scanning for on any ingredient list in this category:
- Isinglass
- Finings
- Gelatine
- Casein
- Albumin
- Unfined
- Unfiltered
- Bentonite
- Look for 'suitable for vegans' or a vegan trademark on the back label.
- 'Unfined and unfiltered' is a reliable proxy on craft beer and natural wine.
- Check Barnivore for a specific brand and vintage before buying in volume.
- Cask ale in the UK is the highest-risk category — isinglass is traditional.
Mistakes to avoid
| Where it catches people out | What to do |
|---|---|
| Guinness-style stouts | Most major stouts stopped using isinglass, but regional and cask versions may not have. |
| Cheap supermarket wine | Often fined; the vegan label is now common enough that its absence is meaningful. |
| Honey-flavoured liqueurs and meads | Contain honey as an ingredient, not just as a fining. |
Alcohol and finings in context
Wine, beer and cider are made from plants but are routinely clarified with animal-derived finings: isinglass from fish swim bladders, gelatine, egg white and casein all bind haze particles so they can be filtered out.
Finings are processing aids rather than ingredients, so they are not required on the label in most jurisdictions. A bottle can be entirely free of animal ingredients and still be non-vegan.
The trend is strongly positive: bentonite clay, pea protein and PVPP replace the animal options at similar cost, and 'suitable for vegans' is now printed on a large share of supermarket wine.
Does certification help? Because finings are invisible on the label, an explicit vegan statement or a Barnivore entry is the only practical verification for drinks.
Vegan alternatives
- N/A — already vegan
FAQ
- Does bentonite end up in the wine?
- No — it settles to the bottom and is racked off before bottling.
- Does isinglass remain in the finished beer?
- Only trace amounts. Vegans avoid it because a fish product was used in production, not because of the residue.
- Are spirits vegan?
- Most distilled spirits are, since distillation removes fining agents. Cream liqueurs and honey-based spirits are the exceptions.
