Today I woke up to find my carboy of hefeweizen spewing the krausen
out and the airlock lying on the floor two feet away. I laugh when I think of
the panic I used to go through when I first started brewing. I would run
through the house gathering up an air lock, a hose and an overflow jug. I would
throw out anything in the sink and start sanitizing the items needed. The whole
time, thoughts that my beer is going to go bad ran through my head. I would put
the blow by tube on and worry about if the beer is going to taste bad when its’
finished. I would get on the internet and research anything I could find about
carboy’s overflowing during primary fermentation. I would call my fellow
brewers and ask them if they think it will be ok, and they would say don’t
worry it will be fine.
After a whole lot of overflows in the middle of the night, I
realize that I have come a long way since then. I have learned a lot over the
years, especially in the overflow department. I always used to think something
would get inside and contaminate my brew when the airlock popped off. After
understanding that the amount of CO2 pressure coming out of the small neck during
the primary fermentation; would not allow that, I am a very calm brewer now. I
also have gotten to know my brews and can usually predict which ones will
ferment like that.
So for that new brewer out there in a mad panic, don’t worry
about it. Be prepared and listen to your fellow brewers and know that its’ all
good.
