So after about 10 years of brewing I have a first for myself. Three and a half weeks ago I brewed a standard Kolsch from NB. All Grain, everything went fine. My question is, is it normal to have a beer still bubbling away after 3 and a half weeks.If so can I still bottle it without worrying about bottle bombs. Thanks in advance.
Bubbling means nothing. Could be from an atmospheric change like barometric pressure causing the beer to offgas. The only way to know for sure is the take a gravity readings a few days apart and determine if it’s reached final gravity.
That’s of course true but a kolsch is brewed at cooler temperature with an ale yeast and that tends to slow down a fermenation similar to the low and slow fermenting of a lager yeast. Main fermenation is yes probably done but waiting is going to help it clear.
I can make my fermentor airlock bubble by just cleaning it with hot water and sans any fluid… put the stopped back in and it’s like a full blown fermentation
