My brother runs a brewery in Fife and a couple of years ago he gave me a Kombucha jar for my Christmas so I could feel like I was joining in on the fermentation fun. Also because he'd intended producing kombucha but decided he CBA.
I did a couple of batches, but really the jar was too small, so I got an enormous drinks dispenser -- one of these 10 litre glass jobs with a spigot for dispensing punch -- and stuck my SCOBY in there. Made some pretty nice raspberry and ginger kombucha (separate flavours), but then kind of lost track of it. When I remembered, I had a vat of vinegar, so I just sort of left it for ages.
A few weeks ago I thought I'd better feed the SCOBY before it crawled out and came looking. Yesterday, we discovered kombucha all over the worktop and I worried it had cracked. But no. The SCOBY is simply so big that it had blocked up the jar and forced what was above it out of the top. I now have a 10 litre jar that is half SCOBY and I can't bring myself to kill it, so I'm wondering if I should get it an aquarium and see if it develops sentience.
