Is It OK To Drink Yeast In Beer?

Yeast is a type of fungus that is commonly used in baking and brewing. In baking, yeast is used as a leavening agent to help the dough rise. In brewing, yeast is used to ferment sugars in grains, such as barley, to produce alcohol.

Yeast can also be used to ferment other foods, such as bread, cheese, and yogurt. There are many different types of yeast, including baker’s yeast, brewer’s yeast, and nutritional yeast.

The Different Types Of Yeast Used In Brewing

In brewing, there are two main types of yeast used:

Ale yeast (Saccharomyces cerevisiae) which ferments at warmer temperatures (60-75°F) and produces a wide range of flavors and aromas, from fruity to spicy.

Lager yeast (Saccharomyces pastorianus) which ferments at cooler temperatures (45-55°F) and produces a clean, crisp taste with little to no fruity or spicy flavors.

These are the main types of yeast used in brewing but there are many other strains of yeast that are used to produce different styles of beer such as wheat beer, lambic, and Belgian-style beers.

Wild Yeast

There is also a wild yeast called Brettanomyces which is used to ferment some beers but it is not as common as the other two. It is known for producing a unique barnyard and fruity flavor profile.

Is It OK To Drink Yeast In Beer

Yes, it is safe to drink yeast in beer. Yeast is a natural ingredient that is used in the fermentation process to convert sugars into alcohol and carbon dioxide.

During the brewing process, the yeast settles out of the beer and is removed before packaging, but some yeast may remain in the final product.

Drinking small amounts of yeast in beer is not harmful to most people. However, if you have a yeast allergy, it would be best to avoid drinking beer that contains yeast.

Also, if you have a condition that affects your immune system, you should talk to your doctor before consuming beer or any other fermented product.

The Benefits Of Drinking Yeast In Beer

There are some potential benefits associated with drinking yeast in beer, as yeast is a source of certain vitamins, minerals, and amino acids. However, it’s important to note that the amount of yeast present in beer is relatively small, so it’s not considered a significant source of these nutrients.

  • Some benefits that have been associated with yeast in beer are:
  • Nutritional yeast is a type of yeast that is rich in B vitamins, minerals, and amino acids. It’s often used as a dietary supplement.
  • Yeast is rich in B-complex vitamins, including B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin).
  • Yeast also contains important minerals like zinc, selenium, chromium, and magnesium.
  • Yeast-based products are also a good source of amino acids, which are the building blocks of protein.

It is really important to remember that beer itself contains alcohol which can have negative health effects when consumed in excess. Therefore, moderation is key. As always, if you have any concerns about your health, it’s best to talk to your doctor before consuming beer or any other fermented product.

The Risks Of Drinking Yeast In Beer

While drinking yeast in beer can have some potential benefits, there are also some risks to consider.

Alcoholism: Alcohol is an addictive substance and excessive drinking can lead to alcoholism, a chronic disease that can cause physical, psychological, and social problems.

Yeast Allergy: Some people may have an allergic reaction to yeast. Symptoms of a yeast allergy can include hives, itching, and swelling. In severe cases, an allergic reaction can cause anaphylaxis, a life-threatening condition that requires immediate medical attention.

Yeast infection: Drinking beer or any other fermented product that has been contaminated with pathogenic yeasts can cause a yeast infection. Symptoms of a yeast infection can include itching, burning, and painful urination.

Interaction with medication: If you are taking any medication, it is important to be aware that alcohol can interact with certain medications and cause side effects or make the medications less effective.

High calories: beer contains calories and excessive drinking can lead to weight gain and obesity.

It’s important to drink beer in moderation and if you have any health concerns, such as a yeast allergy or are taking any medication, it is best to talk to your doctor before consuming beer or any other fermented product.

Alcohol Options For Yeast-Allergic People

People with yeast allergies should avoid drinking beer that contains yeast. However, there are a few options for beer that can be consumed by people with yeast allergies.

Gluten-free beer: Some people with yeast allergies are also sensitive to gluten. Gluten-free beer is made from ingredients such as sorghum, rice, or millet instead of barley or wheat. These beers can be fermented with yeast or yeast-free.

Hard Cider: Hard cider is an alternative to beer that is made from fermented apples and does not contain yeast.

Mead: is an ancient alcoholic beverage made by fermenting honey and water, it does not contain yeast.

Kombucha: is a fermented tea that contains some alcohol (less than 0.5%) and it is yeast-free

These options may not have the same taste or alcohol content as traditional beer and should be consumed in moderation. If you have a yeast allergy, it’s best to consult with an allergist or a doctor before consuming any alcoholic beverages, including the above options.

How To Make Your Own Yeast-Free Beer

Making your own yeast-free beer is possible, but it will require some experimentation and adjustments to traditional brewing methods. Here is one possible method to make yeast-free beer:

  • Start by gathering the ingredients you will need, such as malted barley, hops, and any other desired flavorings.
  • Crush the malted barley to create a coarse powder called a grist.
  • Add the grist to a pot of boiling water, along with the hops, and any other flavorings you want to add. This is called the “mash” process.
  • Allow the mixture to boil for about an hour, then strain out the solids, leaving behind a liquid called wort.
  • The wort is then cooled to room temperature.
  • Add some lactic acid bacteria to the wort, which will ferment the sugars in the wort and produce alcohol. The lactic acid bacteria can be obtained from yogurt or other fermented products.
  • Allow the mixture to ferment for several days, or until the desired level of alcohol is reached.
  • Once fermentation is complete, the beer can be filtered or clarified and then packaged in bottles or cans.
  • Allow the beer to carbonate for a few days before drinking

This method does not produce a traditional beer taste and it will be different from the one made with yeast. Also, it is important to sanitize the equipment and ingredients to avoid contamination by unwanted microorganisms.

As always, brewing beer can be complex and without the yeast, the final product may not have the same flavor profile, carbonation, and alcohol content as traditional beer. If you have any concerns or questions, it may be helpful to consult a brewing guide or to consult with an experienced brewer.


To conclude, yeast is a type of fungus that is commonly used in brewing to ferment sugars in grains and produce alcohol.

There are two main types of yeast used in brewing: ale yeast and lager yeast, which ferment at different temperatures and produce different flavors.

Drinking small amounts of yeast in beer is generally safe, but it is important to consider that excessive drinking can lead to alcoholism and other health issues.

It is also possible to make a yeast-free beer, but it requires adjustments to traditional brewing methods and may produce a different flavor profile and alcohol content than traditional beer.

If you have any health concerns or questions about brewing, it is best to consult with a doctor or an experienced brewer.
