What Makes Wine Not Vegan?
During the fermentation process, wine can become hazy or cloudy due to the presence of molecules such as proteins, phenols, and yeast cells. While these particles are harmless and would naturally settle over time, winemakers often use a process called 'fining' to speed up clarification and achieve a bright, clear appearance that many consumers prefer. The problem for vegans is that many traditional fining agents are derived from animals.
Common Non-Vegan Fining Agents
Several animal products have been used historically and are still used today to fine wine:
- Isinglass: A protein derived from the swim bladders of fish, particularly sturgeon. It is used to clarify white wines.
- Casein: A milk protein used primarily to remove oxidative taint and brighten white wines.
- Egg Whites (Albumin): Used in the traditional fining of red wines to soften harsh tannins.
- Gelatin: A protein sourced from animal hides and bones, used for both red and white wines to remove color and add suppleness.
- Chitosan: A carbohydrate sourced from the shells of crustaceans like crabs and lobsters.
While these agents are largely filtered out before bottling, minute traces can be absorbed into the wine during the process, making it unsuitable for a strict vegan diet. It is also important to note that the use of animal products might not stop at the fining process. Some wineries might use beeswax for bottle seals or glues for labels that are animal-derived.
The Rise of Vegan Alternatives
With the increasing demand for vegan-friendly products, many winemakers have adopted non-animal alternatives for clarification. These methods achieve the same visual clarity without compromising vegan principles.
Here are some common vegan fining agents:
- Bentonite Clay: A type of purified clay with a negative charge that binds to positively charged proteins and yeast particles, causing them to settle.
- Activated Charcoal: A form of carbon that removes unwanted odors and color from wine.
- Pea Protein: A plant-based protein used to clarify wine, often providing a neutral flavor profile.
- Silica Gel: A liquid compound that is often used in combination with other fining agents.
- Vegetable-derived products: Some modern agents are based on legumes or other vegetables.
Another approach is to simply forgo the fining process altogether, resulting in unfined and unfiltered wines. These wines may have a slight haze or sediment at the bottom of the bottle, but they are completely vegan and can offer a fuller, more complex flavor profile.
How to Find a Vegan Wine
Unfortunately, wine labels are not always transparent about the fining process, making it difficult for consumers to know for sure if a wine is vegan. While regulations are evolving in some regions like the EU to provide more transparency, it is still up to the consumer to verify.
Here are some tips for identifying a vegan wine:
- Look for a certification label: Trusted organizations like The Vegan Society, V-Label, or EVE Vegan provide certification marks for vegan products, including wine. This is the most reliable method.
- Check the label for 'unfined' or 'unfiltered': These terms indicate that the wine has not been clarified using any fining agents, making it a safe bet for vegans.
- Search online databases: Websites and apps like Barnivore provide searchable databases where consumers can check if a specific wine brand is vegan.
- Contact the winery directly: A winery's website often provides details on their winemaking philosophy and processes. If not, a quick email or call can clarify their practices.
Comparison of Vegan vs. Non-Vegan Wine Production
| Aspect | Non-Vegan Wine Production | Vegan Wine Production | 
|---|---|---|
| Clarification Agents | Uses animal byproducts like casein, egg whites, gelatin, and isinglass. | Uses non-animal alternatives like bentonite clay, activated charcoal, or pea protein. | 
| Process | Relies on fining to achieve a fast, crystal-clear result. | May use vegan fining agents or opt for an 'unfined/unfiltered' approach, allowing sediments to settle naturally over time. | 
| Appearance | Typically prized for its brilliant, clear visual appearance. | Can be clear or have a slight, harmless haze or sediment if unfined. | 
| Flavor Profile | Clarification can sometimes strip some of the nuanced character of the wine. | Unfined versions may retain more of the natural flavor components and offer a fuller character. | 
| Availability | Historically dominant, widely available in most markets. | Growing in popularity and availability, found in many stores and online retailers. | 
| Certification | No special certification is needed regarding animal products. | Often bears a specific certification mark, though not legally required in all regions. | 
The Vegan Winemaking Process: More Than Just Fining
Some stricter interpretations of veganism also extend to farming and packaging. While less common, some winemakers use animal-derived fertilizers, such as manure or bone meal, in the vineyards. A fully vegan product ensures that every step, from the vineyard to the packaging, is free from animal products. Vegan certification processes, particularly from organizations like BeVeg, often verify the entire production chain to ensure no cross-contamination or hidden animal products.
Conclusion
In summary, the assumption that all wines are vegan because they are made from grapes is incorrect. Many traditional winemaking techniques, specifically the use of animal-derived fining agents for clarification, mean that a large portion of the world's wines are not suitable for a vegan diet. However, with the rising demand for ethical and transparent products, the market for vegan-friendly wines is expanding rapidly. By looking for specific certification labels, checking for 'unfined' or 'unfiltered' declarations, or consulting online resources, consumers can easily find and enjoy vegan wines that align with their values without sacrificing taste or quality. The distinction between vegan and non-vegan wine is not in the ingredients, but in the process, making it a crucial consideration for those on a plant-based diet.

A Final Note on Organic vs. Vegan
It's a common misconception that organic wine is always vegan, but this is not the case. Organic certification pertains to farming practices that avoid synthetic chemicals, but it does not prohibit the use of animal-derived fining agents in the winery. Similarly, a vegan wine is not necessarily organic, as it only addresses the absence of animal products in the process. Consumers seeking both organic and vegan qualities should verify both aspects independently, or look for wines with both certifications. This nuanced understanding is key to making informed choices based on both ethical and environmental concerns.
Note: While many wines that are labeled organic are also vegan, and vice versa, it is important to check the specific certifications and production methods to be certain..
