  • 2 liters of mineral water
  • 1 SCOBY (Symbiotic Culture of Bacteria and Yeasts)
  • 6 tea bags (depending on flavor preference)
  • ½ cup of sugar
  • 1 cup of SCOBY’s stored liquid
  • 1 fabric that allows the liquid to breathe, but without holes so that insects do not enter
  • 1 tie or something to seal the jar
  • 1 glass container


First the tea is prepared with hot water and the respective sachets of its content to remove the liquid. While the tea is being prepared, add the sugar and stir until it dissolves. Then it is allowed to cool.

The second part consists of adding the liquid tea together with the kombucha mushroom liquid to the glass container, since it will serve to activate bacteria and yeast. The SCOBY is placed in the same container. It is normal for it to remain floating. Let rest.

The third step requires care so that the kombucha does not spoil. With the clean cloth, the opening of the container is covered and fixed with a tape, so that there is no opportunity for any external agent to enter the liquid.

Let it rest for two weeks at room temperature of maximum 20ºC, taking care that no sunlight falls directly on the container.

From now on, it can be stored in the fridge for about four days and is ready to drink.

It is normal for a new SCOBY to form adhering to the surface of the container. It is advisable to taste the tea during the two weeks of fermentation to find out what its pleasant effervescence point is, and verify that it does not have a vinegary taste at the end.

It is optional to add aromatic herbs or fruits to flavor the drink. This extra process requires hermetically sealed and kept out of the heat for 4 more days.

Depending on the fruit used, the drink can generate a lot of gas, so it is best to uncover the bottle every 35 hours to prevent the container from exploding. SCOBY can be stored with a little of the liquid, to keep it better and act as an activator for bacteria the next time you want to brew tea.
