Is Wine Vegan?

Wine is not always vegan. While grapes are plant-based, many winemakers use animal-derived fining agents to clarify wine — removing proteins, tannins, and yeast sediment. Common fining agents include isinglass (from fish bladders), casein (milk protein), albumin (egg whites), and gelatin (from animal bones). These agents are filtered out before bottling, but trace amounts may remain, and the process involves animal products.

Why Winemakers Use Fining Agents

Freshly fermented wine is often hazy from suspended proteins and yeast particles. Fining agents speed clarification by binding to these particles and causing them to settle.

Fining Agent	Animal Source	Common Use
Isinglass	Fish bladder	White wine, beer
Casein	Milk protein	White wine
Albumin	Egg whites	Red wine
Gelatin	Animal bones	Red and white wine
