How to Make Kombucha At Home: A Refreshing and Rewarding Journey

Gather Your Supplies for Homemade Kombucha

Before you begin, make sure you have all the necessary equipment and ingredients. Here’s a list of items you’ll need to get started:

  • A large glass jar (preferably one gallon) with a wide opening
  • A breathable cloth or coffee filter to cover the jar
  • A rubber band to secure the cover
  • Organic black or green tea bags
  • Organic cane sugar
  • A SCOBY (Symbiotic Culture of Bacteria and Yeast) SCOBY is actually an acronym that means Symbiotic Culture of Bacteria and Yeast. It’s a fermentor’s best friend and is needed for several fermenting recipes.
  • Starter liquid (previously brewed kombucha)

How to Make Kombucha At Home: Step By Step

Prepare the Sweet Tea Mixture

To create the perfect environment for your SCOBY to thrive, you’ll need to prepare a sweet tea mixture.

  1. Boil water and add the desired number of tea bags based on your jar size (usually one tea bag per cup of water).
  2. Allow the tea to steep for 10-15 minutes.
  3. Remove the tea bags and stir in the sugar until fully dissolved.
  4. Let the sweet tea mixture cool down to room temperature.

Quick Tips:

  • Always handle your SCOBY and brewing tools with clean hands. You don’t want to introduce other bacteria.
  • Toss out a batch that grows white, green, or black mold. These molds mean your tea was infiltrated, and you’ll have to start again.

Add the SCOBY and Starter Liquid

Once your sweet tea mixture has cooled, it’s time to introduce the SCOBY and the starter liquid to kick-start the fermentation process:

  1. Carefully place the SCOBY on top of the sweet tea mixture.
  2. Gently pour the starter liquid (previously brewed kombucha) into the jar.
  3. Cover the jar with a breathable cloth or coffee filter and secure it with a rubber band.

Fermentation Time

Now comes the waiting game! Find a suitable spot in your home where the kombucha jar can sit undisturbed for the fermentation process:

  • Choose a location away from direct sunlight but with consistent room temperature.
  • Let the kombucha ferment for 7 to 14 days, depending on your desired taste. The longer the fermentation, the less sweet and more acidic it becomes.

The Second Fermentation (Optional)

If you prefer a carbonated kombucha with added flavors, you can opt for a second fermentation. Here’s how:

  • Transfer the fermented kombucha into airtight bottles, leaving some headspace.
  • Add flavorings like fruit juice, herbs, or spices.
  • Seal the bottles and allow them to sit at room temperature for 1 to 3 days.
  • Move the bottles to the refrigerator to slow down fermentation and enjoy your fizzy kombucha!

Safety Precautions

While making kombucha at home is generally safe, it’s essential to maintain good hygiene and follow some precautions:

  • Always use clean equipment and wash your hands thoroughly before handling the SCOBY.
  • Avoid using metal containers or utensils, as they can react with the acidic nature of kombucha.
  • Keep an eye out for mold growth, unusual smells, or off-colors. If any signs of spoilage appear, discard the batch and start fresh.

How to Store Homemade Kombucha

Storing homemade kombucha properly is essential to maintain its flavor and quality over time. Here are some guidelines for storing your homemade kombucha:

  1. Refrigeration: Once your kombucha has reached the desired level of fermentation during the first or second fermentation, it’s recommended to store it in the refrigerator. Refrigeration slows down the fermentation process and helps preserve the flavor and carbonation.
  2. Transfer to Bottles: Before refrigeration, transfer your kombucha from the fermentation vessel to individual airtight bottles. This helps prevent exposure to air and maintains the desired level of carbonation. Glass bottles with secure seals or flip-top lids work well for this purpose.
  3. Leave Headspace: When filling the bottles, make sure to leave some headspace at the top. This allows for the release of excess carbon dioxide gas that may continue to be produced during refrigeration, preventing the bottles from becoming overly pressurized.
  4. Flavors and Second Fermentation: If you’ve added flavors or conducted a second fermentation with additional ingredients, be mindful that the flavors may continue to develop in the refrigerator. It’s a good practice to periodically “burp” the bottles by opening them slightly to release any built-up pressure.
  5. Shelf Life: Homemade kombucha stored in the refrigerator can typically last for several weeks to a few months, depending on various factors such as the level of acidity, sugar content, and the specific flavors or ingredients used. The flavor may evolve over time, becoming more tart as the fermentation continues slowly in cold storage.
  6. Enjoy Responsibly: Remember to check the bottles for any signs of spoilage, such as mold growth, unusual smells, or off-colors, before consuming your homemade kombucha. If you notice any signs of spoilage, discard the batch to ensure your safety.

By following these storage guidelines, you can maintain the quality and taste of your homemade kombucha for an extended period, allowing you to enjoy it at your own pace and savor its refreshing goodness.

Health Benefits of Making Your Own Kombucha

Kombucha’s unique taste and potential health benefits have made it increasingly popular, but more research is needed to fully understand its impact on human health.


Kombucha is a fermented beverage, often made with a symbiotic culture of bacteria and yeast (SCOBY). During fermentation, probiotic bacteria are produced, such as species of Lactobacillus and Bifidobacterium. These beneficial bacteria can help promote a healthy gut microbiome, aid digestion, and support immune function.

Improved Digestion

The presence of probiotics in kombucha may contribute to improved digestion and gut health. Probiotics can help restore the balance of beneficial bacteria in the gut, potentially alleviating digestive issues such as bloating, gas, and constipation.


Kombucha contains compounds that may assist in the detoxification process. Glucuronic acid, a byproduct of fermentation, is thought to bind to toxins in the body, aiding their elimination. However, more research is needed to understand the detoxification mechanisms of kombucha fully.

Antioxidant Properties

Kombucha contains various antioxidants, such as polyphenols, which help combat oxidative stress and reduce the risk of chronic diseases. Antioxidants can help neutralize harmful free radicals in the body, potentially protecting cells from damage and promoting overall health.

Potential Immune Support

The presence of probiotics and antioxidants in kombucha may contribute to supporting a healthy immune system. Probiotics can help modulate the immune response, while antioxidants can help reduce inflammation and strengthen the body’s defense against pathogens.

Potential Metabolic Benefits

Some studies suggest that kombucha may have positive effects on metabolism and weight management. However, more research is needed to establish a direct link between kombucha consumption and metabolic improvements.

It’s important to note that individual experiences with kombucha’s health benefits may vary, and the research is still evolving. Additionally, people with certain health conditions, such as compromised immune systems or pre-existing digestive issues, should exercise caution and consult their healthcare provider before consuming kombucha.

As with any dietary change, moderation is key. It’s recommended to start with small amounts of kombucha and gradually increase consumption if well tolerated. Commercially produced and properly fermented kombucha is generally considered safe for most individuals.

However, homemade kombucha may carry additional risks if not prepared and stored correctly. Ultimately, while kombucha shows promise as a potential health-promoting beverage, further research is needed to fully understand its effects and to establish specific dosage recommendations for its various health benefits.


Making your own kombucha at home can be a rewarding and cost-effective way to enjoy this probiotic-rich elixir. With just a few simple steps and a little patience, you can create a personalized brew that suits your taste preferences. So, gather your supplies, and embrace the fermentation process.
