Is beer vegetarian?

In this brief guide, we will answer the query, “Is beer vegetarian?” and will discuss vegetarian-friendly breweries.

Is beer vegetarian?

Yes, most beers are vegetarian. In many cases, beer is created from barley malt, water (and sometimes hop flavoring), and yeast, making it a good choice for vegans and vegetarians alike. Some brewers add finings to their barrel-aged beers to improve clarity and prevent sedimentation. Animal items like isinglass and gelatin as well as plant-derived ones like Irish. The use of animal products in fining of some beers makes them unacceptable for vegetarians.

Beer ingredients unsuitable for vegetarians


Only in the 19th century did beer glasses become popular and British cask ale is served unfiltered, according to Roger Protz, a British writer.

Several types of beers don’t need to be filtered since they don’t include animal ingredients, but British cask ale brewers don’t do this. To keep the yeast in suspension that fermented the wort, and converted sugars from barley into ethanol, beer must be unfiltered. The yeast that remains in the beer gives it a hazy look and a yeasty flavor. To remove the yeast from the beer, finings are employed — these include silicon dioxide, gelatin, polyclar, and isinglass – but there are many more agents that may be used as finings.

Clearing cask ale with isinglass is the most usual practice. If you use isinglass to clear your cask ale, it isn’t considered a vegetarian product since it’s made from the swim bladders of fish, such as sturgeon, but it may also come from polynemidae, sciaenids, and silurids.

Glycerol monostearate

Glycerol monostearate, which is used to generate a froth or head on the final beer, is an example of an animal product utilized in the latter stages of beer manufacturing.


In certain beers, honey is used as an addition to enhance flavor and sweetness. Bee honey is not acceptable for vegans, even though it is commonly seen as safe for vegetarians.


A sugar found in milk, lactose, may be found in certain beers, notably milk stouts, which are not acceptable for those who do not consume dairy products.

What is gelatin, and how is it employed in the production of alcoholic beverages such as beer?

Boiling animal skin, tendons, ligaments, and bones yield gelatin, a protein. It is often present in beer, wine, shampoo, face masks, and cosmetics, and is used to purify them. A common ingredient in marshmallows and jelly candies is glucose.

To make beer crystal clear, gelatin is added to the fermenting process or straight to the beer keg during the brewing process.

When and why is glycerin used in beer?

People don’t realize that Glycerin isn’t always vegan, making it a “hidden non-vegan component.” It’s advisable to avoid glycerin if you don’t know whether it’s derived from plant oil or animal fats since many ingredient labels don’t identify which type of the item is contained.

Tallow, or animal glycerin, is made from beef or mutton fat and is sometimes referred to as such.

What is casein, and how is it used in brewing?

There’s nothing vegan about casein, which is a milk product. When making beer or wine, it’s sometimes used in the finishing process.

Because many individuals have an allergy to casein, the ingredient will be prominently displayed on a beer bottle that includes this component.

Detection apps for vegetarian beer

Numerous methods were discovered that may be highly useful in detecting if a beer (or other alcoholic drinks) is vegetarian or vegan friendly. The Barnivore website and Barnivore mobile apps are these tools.


Barnivore claims to be “your guide to vegan beer, wine, and liquor.” Over 45,000 beer, wine, and liquor items have been entered into a web-based database that contains information on both the ingredients and filtration processes employed. The Barnivore may be found here. 

Apps for iOS

Barnivore’s data may be accessed via four iOS apps that are optimized for mobile use. Green Vegan ($1.99), Vegaholic ($0.99), VeganXpress (Free), and veggie beers (Free) are all available for purchase. It has the most downloads and is now ranked #55 in the “Food & Drink” category on the App Store. Vegaholic has an additional perk: all of its data can be accessed offline, even if you don’t have a mobile service. You may download Veggiebeers for free, making it the most popular of the four.

Apps for Android

Two Android apps use Barnivore’s data in a mobile-friendly way. There’s a vegetable ($1.49) and a VeggieBeers (Free). For Android, we pick VeggieBeers above the other two since it has a greater number of reviews, more downloads, and is completely free.

The Windows Phone

You can now drink vegan on your Windows phone thanks to the Drink Vegan app (Free). Drink Vegan leverages Barnivore’s database much like the other apps on this list.
