i tossed in some kolsch yeast last night into an oktoberfest and 18 hrs later the primary is actually churning as if someone was sturing it! airlock is going crazy, and yet no krussen. this common with kolsch?
I just did my first batch in a Better Bottle and it was well worth it, just in terms of the entertainment value of watching the yeast churning inside the carboy. It's such a beautiful thing to see.
