How to know when kombucha is ready

In this brief guide, we will answer the question “How to know when kombucha is ready” with an in-depth analysis of whether or not how to know when kombucha is ready and how you bottle kombucha. Moreover, we are going to discuss the recipe for homemade kombucha and its benefits of kombucha.

How to know when kombucha is ready?

Following are the ways to know if kombucha is ready or not

  • Temperature affects brew time. If you keep your booch at 78-82 degrees, you should see the first signs of a “baby” SCOBY forming on top of your brew in 4-7 days. It could take weeks if the weather is cold.
  • Because brew times can range from 1-4 weeks depending on temperature, you can look for other indicators, such as your new SCOBY measuring 1 cm thick or more, or use a pH strip to see if the brew registers between 2.5 and 3.

How Do You Bottle Kombucha?

The following are the tips to bottle kombucha:

  • Remove the SCOBY and the Starter Liquid
  • After straining, transfer to bottles
  • Carbonate in Bottle

Remove the SCOBY and the Starter Liquid:

  • Remove your SCOBY and 1/2 cup of kombucha starter liquid with clean hands for your next batch. 
  • Keep your SCOBY in the starter liquid in a non-reactive container until you’re ready to reintroduce it to the fermenter. 
  • Keep in mind that these measurements are for a 1/2 gallon batch; if you’re making a larger batch, you’ll need to set aside more starter liquid.

After straining, transfer to bottles:

  • Using a small funnel, transfer the kombucha into bottles, leaving any yeast sediment or stringy cultures in the fermenter. If you are using fruit, herbs, or juice, put them in now. 
  • Each bottle should be closed with a half-inch of headspace. Clean your fermenter and start your next batch of fermentation.

Carbonate in Bottle:

  • Allow your bottled kombucha to carbonate for 1 to 3 days at room temperature. When bottled, your kombucha will carbonate faster in warmer temperatures and if it has more sugar.

Should You Keep Bottled Kombucha in the Fridge?

Yes. While your kombucha ferments at room temperature and carbonates in the bottle for 1-3 days at room temperature, once carbonation is established, you should store your finished kombucha in the refrigerator.

When you bottle kombucha, there are more sugars than you want to carbonate because a little sweetness tastes good. 

Moving your finished kombucha to the refrigerator will slow down fermentation, whereas storing it at room temperature will continue to convert all those sugars to CO2, resulting in very over-carbonated bottles.

Kombucha Recipe:

The following are the ingredients that are needed to make a kombucha recipe at home;

  • 1 liter of water
  • White sugar (60 gm)
  • 3–4 gm green tea
  • 1 bug ginger or fruit juice (as desired)


  • Boil 1 liter of water with 60 grams of white sugar for a few minutes. After removing it from the heat, add about 2-4gm of green tea leaves and steep for 15-20 minutes.
  • When the tea temperature falls below 30°C, pour it into a sanitized wide-mouth glass container. Cover the SCOBY with a muslin cloth and leave it for a week.
  • You can drink it straight or carbonate it by storing it in an airtight bottle. In the glass bottle, adding some fruit juice or spices (secondary fermentation) can help infuse some interesting flavors. If ginger or fruits are used, an additional 2-3 days in secondary is recommended.

What are the benefits of kombucha?

The following are the benefits of the kombucha;

  • Enhances Immune Health
  • May Help Prevent Heart Disease
  • Digestive Aids

Enhances Immune Health:

Kombucha is high in vitamins and beneficial bacteria that help the immune system. Because kombucha is made from green or black tea, it contains antioxidants and vitamins, such as B vitamins and vitamin C, that help fight infections such as the common cold and flu.

May Help Prevent Heart Disease:

Kombucha made from true tea leaves may help protect heart health by lowering bad LDL cholesterol. According to a study published in the Journal of Nutrition, green tea can lower the risk of heart disease by more than 30%.

While the study focused on brewed green tea, kombucha may still provide these health benefits when made with green tea leaves.

Digestive Aids:

One of the most significant kombucha benefits is its ability to help with digestion. This beverage contains beneficial probiotics that aid digestion. Kombucha is a natural diuretic, which means it aids in the removal of waste and toxins. 

Kombucha consumption may also help to prevent bacterial and fungal infections. According to a study published in the Journal of Medicinal Food, kombucha’s antioxidant activity is the agent for digestive health benefits.
