Kombucha is a probiotic-rich alternative to alcoholic beverages like beer. Sometimes, when I’m feeling fancy, I like pouring kombucha into a wine glass. But is it really better than beer? Below, I’ll be comparing the ins and outs of these two beverages before giving you my final decision. So, let’s get started!

Comparing kombucha vs beer
Kombucha is a fermented tea that has been brewed for centuries, tracing its origins back to China around 220 B.C. The process begins with brewing sweetened tea, usually black or green tea, and then introducing a symbiotic culture of bacteria and yeast (SCOBY). This living organism transforms the sweet tea into a tangy, effervescent beverage over a period of one to two weeks. The result? A low-alcohol, probiotic-rich drink with a unique taste profile.
Note: In this article I’ll be talking about regular kombucha, not hard kombucha, which has a higher alcohol content.
Beer, on the other hand, has a longer history dating back thousands of years. The basic ingredients include water, malted barley, hops, and yeast. The brewing process involves mashing the malted barley, boiling it with hops, fermenting the mixture with yeast, and then conditioning it before packaging. The yeast consumes the sugars in the malt, producing alcohol and carbon dioxide, giving beer its characteristic fizziness and alcoholic content.
Kombucha | Beer | |
Primary ingredients | Tea (black or green), sugar, SCOBY | Water, malted barley, hops, yeast |
Type of fermentation process and fermentation time | Aerobic 1-2 weeks | Anaerobic 2-4 weeks or more depending on the style |
Alcohol content | Generally below 0.5%, can vary | Varies widely, typically 4-6% for beer |
Flavor profile | Tangy, effervescent, slightly sweet | Bitter, malty, hoppy, varies by style |
Probiotic content | Abundant due to fermentation process | Limited, as most are killed during brewing |
Differences between kombucha and beer
Kombucha and beer are both fermented beverages, but they have several key differences, primarily in their ingredients, fermentation process, and alcohol content.
Ingredients
As I mentioned above, the main ingredients in kombucha are tea, sugar, and a SCOBY. The main ingredients in beer are water, malted barley (or other grains), hops, and yeast.
Fermentation process
Kombucha undergoes a process of aerobic fermentation, meaning it requires oxygen. The SCOBY consumes the sugars and produces various compounds, including acetic acid, which gives kombucha its characteristic tangy flavor.
Beer typically undergoes anaerobic fermentation, which means it occurs without oxygen. Yeast consumes the sugars in the wort and produces alcohol and carbon dioxide.
The fermentation duration also differs between the two beverages. Kombucha has a relatively shorter fermentation period of 1-2 weeks, while beer can take anywhere from 2 to 4 weeks or even longer, depending on the style.
Alcohol content
While kombucha is a fermented beverage, it usually contains a relatively low alcohol content, typically around 0.5% but can be higher for homemade kombucha, up to 2% alcohol by volume (ABV). Beer has a significantly higher alcohol content, typically ranging from 4-6% and even higher for some craft and specialty brews.
Flavor profile
Kombucha has a tangy, slightly effervescent flavor. The taste can vary depending on factors such as the type of tea and other ingredients used and the fermentation time. Beer showcases a wide range of flavors, from the bitter and hoppy notes in IPAs to the malty sweetness of stouts. It is quite different from kombucha.
Probiotic content
Kombucha is renowned for its probiotic content, as the fermentation process results in the presence of beneficial bacteria. In contrast, the majority of the probiotics in beer are eliminated during the brewing process.
Can kombucha replace beer?
Kombucha can be a fizzy replacement beverage for beer. If kombucha is below 0.5% alcohol, it’s considered non-alcoholic. So, if you’re looking to reduce your alcohol intake, kombucha is a great alternative! Of course, the flavors are unique, so that might take some getting used to.
Is kombucha a healthier alternative to beer?
Kombucha, with its probiotic content and lower alcohol levels, is a healthier option. Probiotics contribute to gut health, aiding digestion and promoting a balanced microbiome. Plus, kombucha is rich in antioxidants from tea. You just have to be careful with how much you drink and sugar intake, as some brands tend to add a lot of sugar.
Now, beer is usually higher in calories than kombucha, but it does contains essential nutrients such as B vitamins. Some studies actually suggest that light intake may be associated with certain hearth health benefits, but excessive alcohol intake is associated with various health risks. Kombucha doesn’t have those same risks and is usually safe for most people (but not for pregnant women!).
How to store kombucha vs beer
Kombucha is a fermented tea beverage that typically contains live cultures, so it’s best stored refrigerated to slow down fermentation and maintain its probiotic content. It’s best to store kombucha upright to prevent carbonation loss.
Beer is best stored in a cool, dark place, such as a cellar or refrigerator, to preserve its flavor and prevent exposure to light and temperature fluctuations that can lead to “skunking”.
Kombucha vs beer: Which is better
So, which is better? I am in favor of kombucha! It’s a non-alcoholic (or low alcohol) alternative to beer that offers probiotic benefits and antioxidants. Not only is it better for you, but in my opinion, it also tastes better. Not to mention you don’t have to worry about potential drawbacks of drinking alcohol. Here are the best kombucha flavors to try!
FAQs
Kombucha is better. Beer contains alcohol and calories, while kombucha is a fermented tea with potential probiotic benefits and antioxidants.
Kombucha is usually below 0.5% alcohol by volume, while beer typically contains higher alcohol content, typically ranging from 4% to 6% or more. That means you would have to drink 8-12 servings of kombucha to equal one beer.
While kombucha can offer a refreshing alternative, it might not replace beer entirely, especially if you enjoy the unique flavors and higher alcohol content of beer.
Generally speaking, yes. Kombucha is a fermented tea rich in probiotics and antioxidants, offering potential digestive and immune system benefits. However, it typically contains trace amounts of alcohol from the fermentation process. While kombucha can be a healthier alternative for some, those seeking to avoid alcohol entirely should be aware of its slight alcoholic content.
