Wine seems like it should be naturally vegan—after all, it's made from grapes. However, many consumers are surprised to learn that numerous wines use animal-derived products during production. Understanding these non-vegan elements can help you make more informed choices about the wines you purchase.

The Fining Process: Where Animal Products Enter Wine Production

The main reason wine may not be vegan lies in the clarification or "fining" process. After fermentation, wine contains tiny particles of proteins, tannins, tartrates, and phenolics that can make it appear cloudy. While these particles would eventually settle naturally, producers use fining agents to speed up the process and create a clearer, more visually appealing product.

Traditional fining agents often include:

• Egg whites (albumin): Commonly used for red wines to reduce astringency
• Casein (milk protein): Helps remove oxidized characters and bitterness
• Isinglass (fish bladder): Used primarily in white wines for clarity
• Gelatin (animal protein): Removes tannins and improves mouthfeel

These fining agents bind with the unwanted particles in the wine, creating larger molecules that settle to the bottom more quickly. The agents are then filtered out—but their use in production means the final product isn't vegan.

Other Potential Animal-Derived Ingredients

Beyond fining agents, other animal-derived additives might appear in wine:

• Beeswax: Sometimes used to seal bottles
• Honey: Occasionally used as a sweetener
• Carmine/cochineal: A red colorant derived from insects, though rare in wine

The Rise of Vegan Wine Options

As consumer awareness grows, more wineries are adopting vegan-friendly practices. Vegan alternatives for fining include:

• Bentonite clay
• Activated charcoal
• Plant-based proteins (pea, potato)
• Silica-based fining agents

Some producers are also opting for unfiltered wines, allowing natural settling without any fining agents.
