What is a Kombucha Drink

Kombucha is a fermented tea beverage that has gained popularity in recent years due to its potential health benefits and unique taste. It is made through the fermentation of sweetened tea by a symbiotic culture of bacteria and yeast (SCOBY). Here’s how it’s typically prepared:

  1. Brewing: A mixture of black or green tea, sugar, and hot water is prepared. The tea can be sweetened with sugar or other sweeteners like honey or fruit juice.
  2. Cooling: After brewing, the tea is allowed to cool to room temperature.
  3. Adding SCOBY: The SCOBY, which looks like a rubbery disk, is added to the cooled tea. SCOBY stands for Symbiotic Culture Of Bacteria and Yeast. It’s a combination of beneficial bacteria and yeast that kickstart the fermentation process.
  4. Fermentation: The mixture is covered with a cloth or paper towel to allow air circulation while preventing contamination. It’s left to ferment at room temperature for a period of time, typically about 1-2 weeks. During fermentation, the SCOBY consumes the sugar and produces various compounds, including organic acids, probiotics, and a small amount of alcohol. This gives kombucha its characteristic tangy flavor.
  5. Bottling: After fermentation, the liquid is strained to remove the SCOBY and any loose tea leaves. It is then transferred to bottles, often with additional flavorings such as fruit juice or herbs.
  6. Carbonation: The bottled kombucha is left to carbonate for a few days, during which the remaining sugars are further fermented by the yeasts, creating natural carbonation.
  7. Refrigeration: Once the desired level of carbonation is achieved, the kombucha is refrigerated to slow down further fermentation and improve its shelf life.

Kombucha is known for its tart, slightly effervescent, and vinegar-like taste. It often has a trace amount of alcohol, typically below 0.5% alcohol by volume, making it non-alcoholic in most cases.

Many people enjoy kombucha for its potential health benefits, which include probiotics that may support gut health and antioxidants from tea. However, it’s important to note that scientific research on these potential benefits is ongoing, and individual reactions to kombucha can vary.

Commercially, you can find a wide variety of flavored kombucha products in stores, with flavors ranging from fruity to herbal and everything in between. Some people also brew kombucha at home using starter kits and their preferred flavorings.

What are the main ingredients in kombucha?

The main ingredients in kombucha are relatively simple and include the following:

  1. Tea: Kombucha is typically made using black or green tea, although other types of tea, such as white tea or herbal teas, can be used as well. The tea provides the base flavor for the drink and contributes to its color.
  2. Sugar: Sugar serves as the primary food source for the yeast and bacteria in the SCOBY (Symbiotic Culture Of Bacteria and Yeast). During the fermentation process, the sugar is consumed by these microorganisms and converted into various compounds, including organic acids and a small amount of alcohol. The sugar also contributes to the sweetness of the final kombucha product.
  3. Water: Water is used to brew the tea and dilute it to the desired strength before adding the SCOBY. It’s essential to use clean, non-chlorinated water to avoid harming the beneficial microorganisms in the SCOBY.
  4. SCOBY: The SCOBY, or “mother culture,” is the key ingredient in kombucha production. It’s a gelatinous, symbiotic mass of bacteria and yeast that initiates and facilitates the fermentation process. The SCOBY consumes the sugar and converts it into organic acids, probiotics, and other compounds, which give kombucha its unique flavor and potential health benefits.

In addition to these primary ingredients, flavorings such as fruit juice, herbs, or spices can be added to create flavored varieties of kombucha. These flavorings are typically added after the initial fermentation and before bottling.

How is kombucha made?

Kombucha is made through a fermentation process that involves brewing tea, adding sugar, introducing a SCOBY (Symbiotic Culture Of Bacteria and Yeast), and allowing the mixture to ferment. Here’s a step-by-step guide on how kombucha is typically made:


  • Tea (usually black or green tea)
  • Sugar (white sugar, cane sugar, or other sweeteners)
  • Water (clean, non-chlorinated)
  • SCOBY (Symbiotic Culture Of Bacteria and Yeast)
  • Starter liquid (previously brewed kombucha)
  • Flavorings (optional)


  • A large glass or ceramic container
  • A cloth or paper towel and a rubber band or string
  • A stirring utensil
  • Glass bottles for bottling and storing the finished kombucha
  • A funnel (for bottling)
  • pH strips or a pH meter (optional but helpful)
  • A temperature gauge (optional but helpful)


  1. Prepare the Tea: Boil around 4-6 cups of water and steep 4-6 tea bags or the equivalent amount of loose tea in the hot water for about 10-15 minutes. You can adjust the strength of the tea to your preference. Add the sugar (usually about 1 cup per gallon of water) to the hot tea and stir until it dissolves. Allow the sweetened tea to cool to room temperature.
  2. Add SCOBY and Starter Liquid: Once the sweetened tea has cooled, transfer it to a clean glass or ceramic container. Add the SCOBY to the container, along with some starter liquid from a previous batch of kombucha. The starter liquid helps to lower the pH and create an acidic environment that discourages harmful microorganisms.
  3. Cover and Ferment: Cover the container with a cloth or paper towel and secure it with a rubber band or string. This allows air circulation while keeping out contaminants. Place the container in a warm, dark place, ideally at around 75-85°F (24-29°C), and let it ferment for about 1-2 weeks. The fermentation time can vary depending on factors like temperature and personal taste preferences. Check the kombucha periodically to see if it has reached the desired level of acidity and flavor.
  4. Taste and Monitor: During fermentation, you can taste the kombucha using a clean utensil to check its flavor. When it reaches the desired level of tartness, it’s ready to move on to the next steps. The longer it ferments, the less sweet and more acidic it will become.
  5. Bottle and Add Flavor (Optional): If you want to add flavorings, this is the time to do it. You can add fruit juice, herbs, spices, or other flavorings to the kombucha. Use a funnel to transfer the flavored kombucha into glass bottles, leaving some headspace at the top. Seal the bottles with airtight caps.
  6. Carbonation: Allow the bottled kombucha to sit at room temperature for a few days to a week for natural carbonation to develop. This step is optional but is commonly done to make the kombucha fizzy. Be cautious as carbonation can build up, so burp the bottles occasionally by opening them to release excess gas.
  7. Refrigeration: Once the desired level of carbonation is achieved, transfer the bottles to the refrigerator to slow down fermentation. This also helps preserve the flavor and quality of the kombucha.
  8. Enjoy: Your homemade kombucha is now ready to drink. Serve it chilled, and feel free to experiment with different flavor combinations in future batches.

It’s essential to maintain good hygiene throughout the process to prevent contamination. Also, be aware that the SCOBY will grow with each batch, allowing you to reuse it for future fermentations.

Is kombucha alcoholic?

Kombucha can contain a small amount of alcohol due to the fermentation process, but it is typically considered a non-alcoholic beverage. The alcohol content in commercial kombucha is generally quite low, typically below 0.5% alcohol by volume (ABV). This low alcohol content is similar to what you might find in some non-alcoholic beers and is not typically enough to cause intoxication.

The alcohol in kombucha is a natural byproduct of the fermentation process carried out by the yeast in the SCOBY (Symbiotic Culture Of Bacteria and Yeast). During fermentation, the yeast consumes sugar and produces alcohol, along with organic acids and other compounds that give kombucha its unique flavor.

However, it’s worth noting that the alcohol content in kombucha can vary depending on factors like the length of fermentation, temperature, and other variables. Some kombuchas may contain slightly higher levels of alcohol, though they are still generally considered non-alcoholic beverages.

If you have concerns about the alcohol content in kombucha, you can check the label on commercial kombucha products. Many manufacturers list the alcohol content on their labels to comply with regulations and provide transparency to consumers.

If you are avoiding alcohol for health or religious reasons, it’s advisable to select kombucha products with lower or no detectable alcohol content or consider making your own kombucha, where you can control the fermentation process more closely.
