Until this morning, I had never heard of this. Today, I have come across it twice within about 6 hours! Firstly I saw that a radio amateur had made some and then it appeared in the BBC Good Food magazine.
As far as I can see, it is a form of fermented tea. In Japan it refers to tea made from kelp seaweed. I think you can get kombucha in various flavours.
Funny how you can go a whole lifetime without coming across it, then it appears twice! 😄
