Almost a year ago, I wrote the post about how to brew kombucha. I was at the beginning of my Kombucha adventure then and have brewed more than a hundred bottles since. So, let me share some advanced tips with you.
I still use more or less the same technique I described in the original post and it works well for me. It doesn’t mean, I wouldn’t love to have a proper continuous brewing system, but space is a bit restricted in our apartment at the moment.
The beauty of a continuous brewing system is that you always use Kombucha from the bottom and pour fresh tea on the top. And this is the proper way of brewing because there is a lot of yeast at the bottom as opposed to the top were lacto-bacteria tend to be. Using the Kombucha from the top of the brew as a starter guarantees the proper composition of the microorganisms as yeast populates faster. However, if you notice that your Kombucha is very flat, even after days of the secondary carbonation, it means that you don’t have enough yeast in your brew. In this case, keep using the bottom part as a starter until you get a nicely bubbled drink.
Second important tip: don’t keep Kombucha too long in the fridge. A very wise friend of mine told me some time ago that the low temperature promotes the growth of acetic-acid-bacteria but suppresses the growth of lacto-bacteria and yeast. And this is so true! Kombucha kept in the fridge for days is flat and sour.
Thirdly, white sugar works best for brewing Kombucha. I have tried all possible kinds of sugar and must say that nothing beats the ugly, cheap, scary, poisonous white stuff. It doesn’t apply to water kefir, though; it prefers light brown demerara.
Also, the best Kombucha is made of regular black tea. However, I would be delighted to know other people’s experiences. I read all the time about fancy kinds of Kombucha, so there must be something in it. I have tried to mix my tea bags as recommended with fruit teas, but it wasn’t very tasty. I haven’t tried herbs, though. That will be my brewing challenge for this year, I think.
But I keep brewing green tea Kombucha separately and swap Scoby from time to time, i.e. I use green tea Scoby to brew black tea Kombucha and vice versa. It seems to do good for the Scoby’s condition.
That’s all that comes to my mind for the moment.
