Kombucha is becoming increasingly popular in the beverage industry, with consumers flocking to its nutritional benefits and unique flavor profile. But it’s important for those drinking kombucha to understand what exactly goes into making this trendy beverage – and that includes understanding how much alcohol is in kombucha. In this blog post, we’ll dive deep into kombucha to discuss the fermentation process and why alcoholic or non-alcoholic beverages result from that process. We’ll also provide an overview of regulatory standards so everyone can make informed decisions when choosing their next drink. So, if you’re interested in learning all about how kombucha becomes alcoholic (or not), read on!
What Is Kombucha?
Kombucha is a fermented tea beverage made with sweetened black or green tea, starter “tea” from a previous fermentation batch, and a SCOBY (Symbiotic Culture of Bacteria and Yeast). The mixture ferments for 7-14 days to create the finished beverage. During this process, the yeast in the SCOBY is what breaks down sugar and creates alcohol.

Does Kombucha Have Alcohol?
Yes, kombucha can contain alcohol. However, the amount of alcohol in commercially-brewed kombucha is generally very low – around 0.5% or lower ABV (alcohol by volume). For homemade kombucha, the average ABV is about 1-2%, but it can go as high as 4-6% depending how long it has been fermented and how much sugar was used. It’s important to note that the ABV of kombucha is lower than most alcoholic beverages, so drinking kombucha will not lead to intoxication.
How Much Alcohol Is in Kombucha?
The amount of alcohol in kombucha depends on how long it has been fermented, how much sugar was used, and how well the fermentation process was managed. For commercial kombucha brewed to the Alcohol and Tobacco Tax and Trade Bureau (TTB) standards, the alcohol content must be 0.5% or lower by volume. In other words, a 12-ounce kombucha with an alcohol content of 0.5% would have about 6 milligrams of ethanol in it – similar to how a ripe banana contains about 10 milligrams of ethanol.
In contrast, a kombucha brewed at home without following the Alcohol and Tobacco Tax and Trade Bureau (TTB) standards may have an alcohol content higher than 0.5%. The average ABV for homemade kombucha is about 1-2%, but can go as high as 4-6% depending how how long it has been fermented and how much sugar was used.

Classify Kombucha Based On Alcohol Content:
Non-alcoholic kombucha is made with the same fermentation process as traditional kombucha, but with a shorter fermentation period to reduce alcohol content. Non-alcoholic kombucha must have an alcohol content of less than 0.5% ABV in order to be classified as such.
Traditional kombucha has a slightly higher alcohol content, between 0.5% and 1%. This type of kombucha is the most popular on the market, as it balances the tartness of the beverage with its slightly sweet taste.
Hard / High Alcohol Kombucha has an alcohol content higher than 1%, but generally not exceeding 6% ABV. This type of kombucha is meant to taste more like an alcoholic beverage and should be consumed with the same responsible drinking practices as other alcohols.
Why Does Kombucha Contain Alcohol?
Kombucha contains alcohol because of the fermentation process, which is how this beverage gets its flavor and carbonation. During fermentation, sugar from the sweetened tea is broken down by the yeast from the SCOBY. The yeast consumes the sugar and turns it into ethanol (alcohol) and CO2 (carbon dioxide). As with any fermented beverage, how much alcohol is in the final product will depend on how well the fermentation process was managed.
So, does kombucha contain alcohol and how much alcohol is in kombucha? Let’s watching this video to know more!
Factors Influencing The Alcohol Content Of Kombucha
Sugar Content
The amount of sugar in the kombucha is directly related to how much alcohol will be created during fermentation. More sugar means more ethanol produced, and vice-versa.
The Yeast Present
The type of yeast present in the kombucha will also influence how much alcohol is created during fermentation. Some yeasts are more efficient than others at converting sugar into ethanol, so different types of yeast can produce different amounts of alcohol.
Kombucha brewers have little control over the alcohol content of their fermented tea due to a vast array of wild yeast present in various environments. It is impossible to predict which yeasts will end up in our kombucha, and thus how they may contribute or detract from its alcoholic potency!
Fermentation Temperature
Kombucha ferments best between 68°F and 85°F (20°C – 29°C). At higher temperatures, more ethanol is produced while at lower temperatures, the fermentation process slows down.
Fermentation Time
The longer kombucha ferments, the more ethanol that will be created. It’s important to monitor how long your kombucha has been fermenting to ensure it doesn’t become too alcoholic.
The Surface In Contact With Air
Acetic bacteria rely on oxygen to create a vinegary taste in kombucha, transforming the alcohol into acetic acid. To facilitate this process and reduce its alcoholic content, it is important for your fermenting vessel – whether wide-mouthed or narrow – as well as your fermentation space – from roomy kitchen to cramped wardrobe – to have adequate air flow.
The amount of air in contact with the kombucha will also influence how much ethanol is produced during fermentation. The more oxygen present, the more alcohol there is likely to be in the finished product.

How To Make A Low Alcohol Kombucha?
For a low alcohol kombucha, there are several things you can do to reduce how much ethanol is produced during fermentation.
First, use less sugar in your recipe. The more sugar present in the brew, the more alcohol that will be created.
Second, make sure the temperature of your fermenting environment is at or below 78°F (25°C). This will slow down the fermentation process which in turn slows how much ethanol is produced.
Third, limit how long your kombucha ferments. As mentioned above, the longer it ferments the more alcohol that gets created so it’s important to make sure you stop the fermentation at the right time. You can do this by tasting your kombucha regularly or using a pH meter.
Fourth, use an airtight fermenting vessel and make sure there is adequate air flow in the fermentation space. This will help reduce how much ethanol is produced during fermentation.
Finally, if you’re still struggling to get the alcohol level down, look into adding a “neutralizing agent” such as lemon juice or citric acid to your brew. This will help reduce how much ethanol is created during fermentation.
How To Make A High Alcohol Kombucha?
If you’re looking to make a higher alcohol kombucha, there are several things you can do to increase how much ethanol is produced during fermentation.
Use more sugar in your recipe, consider bumping up your sugar levels (½ cup per litre). The more sugar present in the brew, the more alcohol that will be created. Maintaining a fermentation temperature of 28-35°C for 7-10 days. This will speed up the fermentation process which in turn increases how much ethanol is produced.
Finally, use a wide-mouthed fermenting vessel and make sure there is adequate air flow in the fermentation space and look into adding ingredients such as honey or fruit juice to your brew. This will help increase how much ethanol is created during fermentation.

What Are The Purported Health Benefits Of Kombucha?
Kombucha is believed to provide a range of health benefits. These include improved digestion and gut health, increased energy levels, better mental clarity, and even a boost in the immune system. It is also thought to help protect against disease and improve overall well-being.
However, how much alcohol is present in kombucha can reduce how much of these purported benefits you receive. The higher the alcohol content, the less beneficial it may be for your health. For this reason, it is important to take steps to reduce how much ethanol is present in your kombucha before consuming it.
The Best Kombucha Brands To Buy:
When it comes to how much alcohol is in kombucha, the best brands are those that offer low-alcohol kombuchas. Brands such as Health-Ade, GT’s Synergy, Buchi and Humm all offer a range of low-alcohol Kombucha products. These brands are also committed to using only the highest-quality ingredients and brewing processes, ensuring that their products are safe, healthy and delicious.

Conclusion: How Much Alcohol Is in Kombucha?
Kombucha is a popular fermented beverage that can contain varying levels of alcohol, depending how long it has been fermented and how much sugar was used in its production. Commercially-brewed kombucha must adhere to Alcohol and Tobacco Tax and Trade Bureau (TTB) standards, with an alcohol content of 0.5% or less, while homemade kombucha may have a higher ABV. Regardless of how much alcohol is in kombucha, it’s important to make informed decisions when choosing this beverage. Knowing how much alcohol is in kombucha can help you make the right choice for your lifestyle and preferences. Thanks for reading at irishsetterpub.com
