Haha.. SCOBY hotel. I like it.
I've never freezed a SCOBY myself but I don't see much point unless you want to ship it somewhere. If you have a few small mason jars then you can just keep SCOBY pieces with starter in the jars for awhile.
The other option is, give a SCOBY to a friend! A buddy of mine gave me my first SCOBY and I've been drinking Kombucha ever since. Spread the love.
