1. Prepare a glass bottle that can hold 2-5 Jin of water and a pair of chopsticks, and disinfect them with boiling water for later use.
2. Fill the kettle with clear water (calculated according to the ratio of one kilogram of water to one black tea fungus), and then wrap a little tea and a little sugar with clean gauze (any tea is ok, black tea is better, and the concentration of tea is lighter than the tea you usually drink, just a little color; Generally, put about 2.5 grams of tea and one or two grams of sugar according to a catty of water. The sweetness should not be too light or too sweet, and it is better to be delicious. Tea and sugar are wrapped in clean gauze. Put the wrapped tea leaves and sugar into the kettle, and then boil the water until the sugar is completely dissolved in the water.
3. Remove the boiled tea syrup from the fire and cool it. When the tea syrup drops below 40℃, take out the gauze bag containing tea leaves and white sugar, and pour the tea syrup into the glass bottle. Don't fill it, but leave some gaps to facilitate air circulation.
4. Pour all the strains of black tea fungus (including mother fungus and fungus liquid) into the glass bottle, then cover the bottle mouth with clean gauze and tie it with a rope, and observe it in a well-lit place, and try not to shake it. The temperature is between 25 and 30 DEG C, and it takes about 4 days; The temperature is between 15-25℃, which takes about 6 days. 8 days below 65438 05℃. The best way to test the success of black tea fungus is that as long as a transparent colloidal film begins to grow on the surface of the cultivated new black tea fungus, it is considered successful. When the old strain turns yellow and black, it can be discarded to make the new strain grow faster.
5. When the liquid level of the cultivated black tea fungus becomes thicker and bigger, divide it into multiple pieces according to the above method, move it into other glass bottles, add tea syrup, and let it continue to ferment. As long as we master the method in the production and pay attention to all the utensils for cultivating bacteria being disinfected with boiling water, and do not dye with oil, salt or wine, a black tea fungus can be passed down from generation to generation.
6. After the successful cultivation of black tea fungus, it can be directly drunk. When you want to drink, you can pour the successfully cultivated black tea fungus liquid into a cup or bowl, just like drinking tea at ordinary times. Drink as much as you want, unlimited times, and countless times a day. When your cultivated black tea fungus liquid turns sour for a long time, you can add white sugar water at any time until you feel sweet and sour.
7. Kombucha can be cultivated all year round all over the world.
