SCOBY – kombucha sponge or how to grow one at home
SCOBY is an acronym for Symbiotic Culture Of Bacteria and Yeast.
This is the most important element to have a nice kombucha drink.
What is it actually?
SCOBY is a jelly-like bulk with a cellulose composition that is a home to the bacteria and yeast in the beverage.
It develops on the surface of the drink and takes the shape of the container in which you put it. Phrases “kombucha sponge” or “kombucha culture” are commonly used.
To produce a good drink, you must have a healthy and well-developed sponge. The internet is full of offers, but you can grow a sponge yourself.
It is necessary to be prepared for the production of kombucha tea following the instructions here – instead of a sponge put 500 ml natural, unpasteurized kombucha drink in the jar.
Cover the jar with gauze. Tighten with a rubber band and leave in a warm but not sunny place.
In a few days, you will see that a soft, translucent membrane appears on the surface.
After few more days, the sponge will gain density and thickness.
When it gets 3-4 mm it’s ready to use it to make a kombucha drink.
The ready drink will not be drinkable (it will be quite acidic) but will be a great start for your next kombucha challenges.
