Wine fining agents

Common US / international name: wine fining agents

Origin: Processing aids that clear haze from wine or beer before bottling.
What it depends on: Fining can use isinglass, casein, egg white, or gelatin (animal), or bentonite, silica, plant proteins, and charcoal (non-animal). Bottles often omit the processing aid when residues are below thresholds.
Where it typically appears: Many conventional wines and some beers; vegan-labeled bottles avoid animal finings.
Regional note: Allergen labeling rules for egg and milk fining residues differ by market (EU stricter than many US labels).
