This is the same recipe you would use when you are making regular kombucha except you use coffee instead of tea. Once you use your SCOBY for coffee kombucha, you can't use it again in regular kombucha tea.
I swear by Kefir! It works so well I may be able to stop taking a pill for irritable bowel AND it's dramatically reduced the symptoms of a belly bug I've picked up. A real miracle drink as far as I'm concerned.
