Quick Answer: Does Kombucha Contain Alcohol?
The short answer is - it’s complicated. Kombucha typically does contain small amounts of alcohol as a result of the fermentation process involving yeast and bacteria cultures. However, most kombucha sold in stores has low enough levels of alcohol to qualify as non-alcoholic (typically this is 0.5% ABV). Read on to learn more about Kombucha and its alcohol content.
Understanding Kombucha and Its Alcoholic Content
What is Kombucha?
Kombucha is a fermented tea beverage created by combining sweetened tea with a SCOBY (Symbiotic Culture of Bacteria and Yeast), which initiates a natural fermentation process. This process converts the sugars in the tea into organic acids, carbonation, and various bioactive compounds, resulting in a tangy and slightly effervescent drink. It's known for its unique and complex flavor profile, which can range from mildly sweet to tangy and sour, depending on factors such as the tea used and the fermentation time. Some people brew their own kombucha; however, there are also many ready-to-drink kombucha options available in stores.
Health Benefits of Kombucha
Kombucha is often touted for its potential health benefits, although it's essential to note that scientific research is ongoing, and some claims may require further investigation. Some of the reported health benefits of kombucha include:
Probiotics: Kombucha is a source of beneficial bacteria and yeast, which can support gut health by promoting a balanced microbiome and aiding digestion.
Antioxidants: Kombucha contains antioxidants, such as polyphenols, which can help combat oxidative stress and reduce the risk of chronic diseases.
Improved digestion: The probiotics and enzymes in kombucha may aid in the digestion of food and alleviate digestive issues like indigestion and bloating.
Detoxification: Kombucha may support the liver's natural detoxification processes due to the presence of antioxidants and organic acids.
Immune system support: The gut and immune system are closely linked, and a healthy gut can contribute to a robust immune response. Probiotics in kombucha may play a role in strengthening the immune system.
As with all things, individual circumstances may vary. If you have specific health conditions, check with your healthcare professional about whether kombucha might be beneficial. Additionally, excessive consumption of kombucha means extra calories and, for some, digestive discomfort. Moderation is key!
Does Kombucha Contain Alcohol?
Yes, kombucha typically contains a small amount of alcohol. During the fermentation process, the yeast and bacteria cultures in kombucha produce alcohol as a byproduct. The alcohol content in commercial kombucha products is usually less than 0.5% alcohol by volume, which is generally not enough for it to be considered an alcoholic drink, and keeps it safe for all age groups. However, homemade kombucha or products with longer fermentation times may have slightly higher alcohol content. If you have concerns about alcohol consumption, you can check the label on commercially produced kombucha to confirm its alcohol content.
Examining Alcohol Levels in Kombucha
Store-bought Varieties
Store-bought kombucha does contain a small amount of alcohol, but it typically contains less than 0.5% alcohol by volume. This level of alcohol is generally considered non-alcoholic and safe for all age groups. However, it may not be appropriate for those wishing to avoid even trace levels of alcohol for health, religious or other reasons. Commercially produced kombucha is regulated to ensure that it adheres to this low alcohol content standard. However, it's important to note that the alcohol content in kombucha can vary slightly from one brand or product to another, so be sure to check the label if you have specific concerns about alcohol consumption.
Homemade Brews
The alcohol content in homemade kombucha can vary depending on several factors, including the length of fermentation, temperature, and the specific ingredients used. In general, homemade kombucha is reported to contain anywhere from 0.5% to 3% alcohol by volume or even slightly higher in some cases. The alcohol content typically increases as the fermentation process progresses, so if you ferment your kombucha for an extended period or under conditions that promote higher alcohol production, the alcohol content may be at the higher end of that range.
If you want to control the alcohol content in homemade kombucha, you can adjust the fermentation time and conditions. Shorter fermentation times and cooler temperatures tend to produce kombucha with lower alcohol content, while longer fermentation times and warmer temperatures can result in higher alcohol content. It's essential to be aware of the alcohol content if you're concerned about its effects or are avoiding alcohol for any reason, such as pregnancy, medical conditions, or dietary preferences. If you’re avoiding alcohol, homemade kombucha may not be the best option for you due to the variability of alcohol content.
Factors Influencing Kombucha's Alcohol Content
Sugar Content
The sugar content in kombucha significantly affects the alcohol level during fermentation. Sugar in sweet tea provides the yeast in the SCOBY with a substrate for fermentation, leading to the production of alcohol. The more sugar and longer the fermentation, the higher the alcohol content. So, one possible way to lower the alcohol content in kombucha is to adjust the sugar levels in the brew.
Types of Yeast
The type of yeast used in kombucha fermentation can influence alcohol levels. Saccharomyces cerevisiae, a common yeast in brewing, has a higher alcohol tolerance and tends to produce more alcohol compared to other yeast strains typically found in kombucha, such as Brettanomyces or various wild yeast strains. Using a yeast strain like Saccharomyces can result in a higher alcohol content in the final kombucha brew, while wild or alternative yeast strains may yield lower alcohol levels, as they often focus on producing other flavor compounds. Therefore, yeast selection plays a crucial role in determining the alcohol content of kombucha, with different yeast strains offering a range of potential outcomes.
Fermentation Temperature
Fermentation temperature plays a significant role in influencing alcohol levels in kombucha. Warmer temperatures generally promote more rapid yeast activity, which can lead to increased alcohol production. At higher temperatures, the yeast strains in the kombucha culture tend to ferment sugars more quickly, potentially yielding higher alcohol levels. Conversely, cooler temperatures slow down the fermentation process, which can result in lower alcohol content as the yeast works more slowly. Therefore, careful temperature control is essential when making kombucha, particularly when levels of alcohol in the final product are a concern.
Duration of Fermentation
The length of fermentation is a critical factor affecting the alcohol content in kombucha. During the fermentation process, the yeast in the SCOBY consumes the sugars in the sweet tea and produces alcohol as a byproduct. The longer the fermentation process, the more time the yeast has to convert the sugars into alcohol. This means that a longer fermentation period results in higher alcohol content in the final product. Brewers should monitor alcohol content carefully the longer the kombucha brews to keep levels of alcohol in check.
Oxygen Exposure
Oxygen exposure plays a significant role in regulating alcohol levels in kombucha during the fermentation process. When kombucha is exposed to oxygen, it promotes the conversion of alcohol into acetic acid (vinegar). This is why it is recommended to use breathable cloth or paper towels secured with rubber bands to cover the fermenting kombucha. By allowing oxygen in, it encourages the yeast to produce less alcohol and more acetic acid, resulting in a more tangy and less alcoholic final product. However, excessive oxygen exposure can also lead to over-oxidation, adversely affecting the flavor and quality of the kombucha. Balancing oxygen exposure is crucial to achieve the desired flavor profile and alcohol content in the end product, making it an important consideration for homebrewers.
Hard Kombucha: Exploring the Alcoholic Varieties
Differentiating "Hard Kombucha"
Hard kombucha is a variation of traditional kombucha that has undergone additional fermentation to increase its alcohol content, typically to levels more in line with alcoholic beverages. While standard kombucha typically contains less than 0.5% alcohol by volume, hard kombucha is deliberately brewed to have a higher alcohol content. This higher alcohol content is achieved by extending the fermentation process and allowing the yeast to continue converting sugars into alcohol beyond what is typical in non-alcoholic kombucha. Hard kombucha may also be subject to regulations governing alcoholic beverages, including age restrictions and labeling requirements, depending on local laws and regulations. It offers a unique alternative for those who enjoy kombucha's probiotic benefits and tangy flavors while seeking an alcoholic beverage option but will not be appropriate for those living a non-alcoholic lifestyle.
Alcohol Content in Popular Brands
The alcohol content in kombucha varies by brand. According to their websites, here is the alcohol content of some of the most popular kombucha brands available (always check the product label before consuming, as variation can occur!). Note that 0.5% ABV or less is typically considered non-alcoholic for labeling purposes and is in line with other naturally occurring alcohols in food (e.g. ripe fruit can have a similar ABV). Although it is considered alcohol free, the trace amounts still may not be appropriate for those with specific concerns about alcohol.
Remedy Kombucha - Less than or equal to 0.5% ABV
Silver Swallow Luxury Kombucha - 0.5% ABV
GTS Classic Kombucha - 1% ABV
Brew Dr. Organic Kombucha - Less than 0.5% ABV
Health ADE - Less than 0.5% ABV
Note also that kombucha often has live cultures in it, so unrefrigerated kombucha in particular can continue to ferment. Be sure to store kombucha in the fridge to slow the process and be aware of best before dates on products to minimize the risk.
Can you get Drunk off Kombucha?
Given the typically relatively low alcohol content, most kombucha is is well below the level of alcohol required to make you drunk. Consuming standard commercial kombucha, even in reasonable quantities, is unlikely to lead to intoxication. However, it's essential to note that the alcohol content can vary among brands and homemade batches. If kombucha is improperly brewed, allowed to ferment for an extended period, or stored incorrectly, it could potentially develop higher alcohol levels. In such cases, consumption could lead to intoxication. So while for the most part, getting drunk off kombucha is not a concern, it is important to be aware of the risks and variations, and make health and consumption decisions according to your personal needs and concerns relating to alcohol.

Final Thoughts
If you’re avoiding alcohol, you may be looking for a satisfying alternative to drink, and kombucha may be an option to consider. On the plus side, it has some of the qualities of alcoholic drinks, such as carbonation and a subtle tangy bite, that can make an excellent replacement for beverages such as sparkling wine. Additionally, kombucha may have health benefits including improved gut health and detoxification, which may support your body as it readjusts to life without alcohol.
On the other hand, consuming too much kombucha can lead to excess calories and for some people, upset stomachs. Additionally, given the presence of trace amounts of alcohol (and possible higher amounts, for example, in home brews or improperly stored commercial products), it may not be the right choice for those determined to avoid even trace amounts of alcohol in their diets.
As with most things, be informed about the risks and rewards of consuming kombucha for your personal circumstances, always read the labels carefully, and if you have any doubts, speak with your healthcare professional to be sure.
