I brewed it just like regular kombucha, but I mixed some herb in with the tea leaves. Then in the second ferment I added strawberries. It is awesome!
Below is a link to my website explaining how to brew kombucha (if you never have). To make 'hempbucha, just add some herb to your tea leaves before you boil. I boiled it extra long to make sure I extracted everything into the tea. Alcohol content is quite low (unless you ferment it longer). Try it, you'll like it !
