Kombucha is an increasingly popular fermented (and delicious) tea beverage and recipe ingredient, but one of the questions many potential consumers have is how much alcohol is in the stuff. The answer to this question isn’t simple and can vary with each individual bottle!
If you are looking to get your buzz on, kombucha may not be the thing to do it with. Although kombucha can contain some alcohol, most varieties usually only have tiny amounts. In fact, usually far, far below what you would find in most beers or wines. Let’s look at it in a bit more detail.
Alcohol Content of Kombucha
Kombucha can contain anywhere between 0-3% ABV (alcohol by volume). This means that some bottles won’t contain any alcohol, while others might have a trace amount of alcohol.
When making kombucha at home, you can further control the amount of alcohol produced, as homemade kombuchas can contain a much higher ABV. However, due to regulations, many commercial producers are limited to producing 0.5% ABV or less.
Typically, homemade kombucha contains 1% to 2.5% alcohol content, whereas commercial kombucha contains less than 0.5% alcohol. It is marketed and sold as a non-alcoholic beverage, as it fits within the maximum ABV limit set by many countries to maintain its non-alcoholic status. A beverage is only considered alcoholic after it hits a 1.2% ABV.
For reference, the average alcohol content of other popular alcoholic beverages is:
- Beer (3% to 8%),
- Wine (11% to 14%), and
- Hard liquor (35% to 50%).
Why Does The Alcohol Content Of Kombucha Vary So Much?
To control the alcohol content of your kombucha, a few factors need to be considered.
- Sugar Content: The amount of sugar you start with can influence the alcohol content in kombucha, as yeast consumes sugar and produces alcohol. However, there’s a limit to this. You can’t simply add more sugar and expect to get a high-alcohol product. Kombucha is a delicate balance of yeast and bacteria, and too much sugar could disrupt this balance.
- Yeast Strains: Different yeast strains can produce different amounts of alcohol. Some yeasts are high-alcohol producers, while others are not. So, choose your yeast strain accordingly.
- Temperature: The temperature at which kombucha is fermented can also affect its alcohol content. Yeast activity increases at warmer temperatures, leading to more alcohol production. At cooler temperatures, the bacteria in kombucha are more active than the yeast, producing more acids and making the kombucha sourer rather than more alcoholic.
- Fermentation Time: The length of time kombucha is left to ferment can influence its alcohol content. If kombucha is allowed to ferment for longer, it will generally have less alcohol. This is because the bacteria in the kombucha consume the alcohol produced by the yeast, converting it into acetic acid (vinegar).
- Aeration: The air exposure kombucha gets during fermentation can affect its alcohol content. The bacteria in kombucha need oxygen to convert alcohol into acetic acid. So, the more air the kombucha is exposed to, the less alcohol it will generally have.
Why Is The Alcohol Content in Commercial Kombucha So Low?
If the ABV content of kombucha ever goes above 0.5% at any point, it’s considered an alcoholic beverage by law, which brings a whole bunch of regulations and taxes. To avoid this, kombucha makers try to keep the alcohol level always below 0.5%.
How do they do this? Aside from carefully monitoring all the factors listed above, they also use specially shaped brewing tanks and fermenters. These can help speed up the fermentation process and make staying within the ABV limit easier.
Kombucha is made using a SCOBY (Symbiotic Culture of Bacteria and Yeast). The yeast turns sugar into alcohol and carbon dioxide, and the bacteria use oxygen to turn the alcohol into organic acids. The key to keeping the alcohol levels down is creating a balanced environment for the yeast and bacteria, which the specialized equipment can help with. Their unique shape allows the bacteria to work faster, consuming the alcohol before it exceeds the legal limit.
FAQs
Most commercial kombucha drinks contain less than 0.5% alcohol by volume, which is considered non-alcoholic by US standards. However, home-brewed versions can have higher alcohol percentages.
Kombucha contains a small amount of alcohol as a result of the fermentation process. The yeast in the kombucha culture consumes the sugar and produces alcohol and carbon dioxide.
It’s highly unlikely to get drunk from drinking kombucha because the alcohol content is typically very low. However, consuming large quantities or certain high-alcohol varieties could potentially give you a buzz!
Because kombucha contains both caffeine from the tea and a small amount of alcohol, it may not be recommended for children and pregnant or breastfeeding women.
Making completely non-alcoholic kombucha is challenging since the alcohol is a natural byproduct of the fermentation process. However, the alcohol content can be minimized by shortening the fermentation time or using specific techniques and strains of yeast and bacteria.
No, the alcohol content can vary between different brands of kombucha. Some brands also make “hard” kombucha with a higher alcohol content.
