What Makes Wine Non-Vegan?

Wine is typically viewed as an acceptable drink for vegans. However, certain elements of the production process may render it non-vegan. Many winemakers use animal products or byproducts in the process of making their wines. These animal products can be used for fining agents, flavourings, and clarifying agents.

So, before making a purchase, you should research which wines are vegan-friendly due to the potential use of animal products in winemaking. It’s worth exploring the various animal-derived components that can be used in winemaking to gain an understanding of how this affects a wine’s vegan status. Let’s further discuss this in the next section.

Animal Products in Winemaking

The winemaking process is not as simple as it seems. Although grapes are the main ingredient, other components, such as animal products, may be used in winemaking, thus potentially making some wines unsuitable for vegans. Unfortunately, some of these ingredients may contain animal products, and this could mean that certain wines may not be suitable for vegans.

Animal products used in winemaking, such as egg whites and isinglass, can be avoided when selecting vegan wines. Moving on to the next heading of “Fining Agents Used in Winemaking,” it’s important to understand which fining agents are suitable for vegans.

Key Takeaway: Vegan-friendly wine is not always easy to find, as many wines contain animal-derived ingredients like gelatin and casein. To make sure you get your money’s worth, do your homework before buying – look out for ‘suitable for vegans’ labels or consult websites such as Barnivore that list vegan wines.

Fining Agents Used in Winemaking

Fining agents are used in winemaking to remove unwanted particles from the wine, such as proteins, tannins and other compounds that cause cloudiness. This process is known as clarification or fining, and it helps to improve the clarity, colour and flavour of the finished product. The most commonly used fining agents include bentonite clay, egg whites, casein (a milk protein), gelatin (animal protein) and isinglass (fish bladder).

bentononite clay

Bentononite clay is a type of sedimentary rock which has been heated to high temperatures, resulting in the formation of a fine powder. It’s often used in combination with other agents to clarify white wines but can also be found in reds. Egg whites are another popular choice for clarifying white wines; they bind with tannins and other impurities before being removed during filtration. Casein is a milk-derived protein which acts like glue by trapping suspended particles before settling out of suspension. Gelatin is an animal-based agent made from collagen extracted from bones or skin; its molecules attract proteins so that they form larger clumps that can then be filtered out easily. Isinglass comes from fish bladders and works similarly to gelatin – it binds with proteins causing them to settle faster than normal when cold-stabilized.

Organic winemakers, striving to adhere to ethical vegan principles and practices, eschew the use of animal-based finings in favour of more natural methods such as bentonite clay or plant-derived alternatives like pea starch and vegetable gum arabic. Nevertheless, if a producer feels there is no feasible alternative available, they may still opt for using these non-vegan fining agents – albeit always with disclosure on their product label so that consumers are fully informed. Now let us explore further by looking at whether organic wines can be considered vegan or not. 

Is Organic Wine Vegan?

Organic vino is crafted from grapes cultivated without the implementation of chemical fertilizers, pesticides, or other artificial elements. Many vegans seek out organic wines as they wish to ensure no animal-derived ingredients are present in the winemaking process. But does that make them vegan?

No straightforward answer exists. Organic wines may still contain non-vegan ingredients depending on the type of fining agents used during production. Fining agents are used to clarify and filter out unwanted particles from wine, such as proteins, tannins, and other compounds. Common fining agents include egg whites, casein (a milk protein), gelatin (derived from animals), and isinglass (made from fish bladders). While some organic wineries do not use these animal-based fining agents at all, others may choose to use vegetarian alternatives like bentonite clay or carbon filtration instead.

Another factor to consider when determining if an organic wine is vegan-friendly is whether it has been filtered through bone char which can be derived from cow bones or even fish bones in some cases. Bone char helps remove colourings and impurities from the finished product, but many vegans try to avoid this method due to its potential for containing animal products.

Key Takeaway: Organic wines may not always be vegan-friendly, depending on the type of fining agents used during production and whether it has been filtered through bone char. However, with a bit of research, you should have no trouble finding suitable vegan options that are free from animal byproducts. In conclusion, vegan wine drinkers have plenty of options for cruelty-free consumption.

How to Tell if a Wine Is Vegan

To ensure wine is vegan-friendly, look for the Vegan Society logo on its label; if this isn’t available, other signs should be looked out for. This logo will guarantee that no animal products have been used in either the production or bottling of the wine. However, this isn’t always possible, so it’s important to know what other signs to look out for when determining whether a bottle of vino is vegan-friendly or not.

Another thing to note when looking for a vegan wine, one should be mindful of the colour; white wines often require more clarification than reds due to their lighter hue and thus, there is an increased probability that animal proteins were added during production – something worth considering if you want your glass of vino sans guilt. 

Key Takeaway: It’s essential for vegans to know what signs to look out for when choosing a bottle of wine, as some may contain animal-derived fining agents. For example, white wines often require more clarification and thus have an increased chance of containing animal proteins – something worth bearing in mind. Organic wines might also not be suitable due to their potential use of animal derivatives during processing and filtration stages.

FAQs in Relation to Why Is Wine Not Vegan

What ingredients in wine are not vegan?

Wine can contain a variety of non-vegan ingredients, such as gelatin, isinglass (fish bladder), egg whites, casein (milk protein) and albumen (egg whites). Many wines also use animal-derived fining agents during the production process. These include bentonite clay, activated charcoal and even bull’s blood. All these substances are used to clarify wine by removing proteins that cause haze or cloudiness in the finished product. To ensure your wine is vegan-friendly it is best to look for labels indicating ‘suitable for vegans’ or ‘unfined/unfiltered’ on the bottle.

Is wine naturally vegan?

No, wine is not naturally vegan. Wine production involves the use of animal-derived products such as gelatin and casein in the fining process. These substances are used to remove proteins, yeast, cloudiness and other organic particles from wines before they are bottled for sale. While some winemakers may choose to avoid these ingredients or substitute them with plant-based alternatives, many do still contain animal derivatives, making them unsuitable for vegans.

Why is vegan wine different?

Vegan vino is distinct from other wines in that it has no animal-derived components. Vegan wines are made without the use of animal products, such as eggs, milk or gelatin, which are commonly used in winemaking processes. Additionally, vegan wines must also be free of fining agents like casein (a milk protein), albumin (egg whites) and isinglass (fish bladder protein). These fining agents help to clarify the wine by removing proteins that cause cloudiness and can give off flavours that would otherwise make a wine unpleasant to drink. Therefore, vegan wines offer drinkers an alternative option for enjoying their favourite beverages without compromising on quality or taste.


To sum up, vegans must take into account the potential presence of animal-derived products when selecting a wine. While some wines are labelled as ‘vegan’, not all of them can be considered so due to the use of animal products in winemaking processes or fining agents used for clarification. Knowing how to tell if a wine is vegan and understanding why certain wines may not be suitable for vegans will help ensure you make an informed decision about your drinking habits. There’s no need to miss out on enjoying a glass of vino even if you now know, “why is wine not vegan”, you just have to be careful on picking one that’s a truly vegan wine.
