Porcine Gelatin (Beverage Fining) — Hidden Processing Agent — Is It Vegan?
Also known as: Wine gelatin, Beer gelatin, Fining gelatin, Collagen hydrolysate
Not Vegan
This processing agent is derived from animals or their byproducts.
Not required on labels
Not required on wine or beer labels in most jurisdictions. No allergen declaration typically required for gelatin (not a listed allergen under EU/UK law in beverages).
Source
Derived from the skin, bones, and connective tissue of pigs. Produced by acid or alkali hydrolysis of collagen.
Used In
Wine fining (tannin removal, clarification), beer clarification (particularly traditional British real ale conditioning), juice clarification.
How to Avoid
Use Barnivore or similar services to identify vegan wines and beers. Look for products explicitly certified vegan or labelled 'no animal fining agents used'.
Editorial Notes
Gelatin works as a wine fining agent by forming complexes with tannins — positively charged gelatin binds to negatively charged tannins, and the complex flocculates and settles. This is why gelatin fining is used primarily for red wines (high tannin) rather than whites. The settled gelatin-tannin complex is removed as sediment, so the final wine contains no detectable gelatin protein — but the process is not vegan.
