I know this is a question that has been asked and answered, but I am still concerned. This is my 3rd batch of beer, an Imperial Stout. The airlock is bubbling like crazy and filling with foam and beer! It is actually overflowing.

I took the airlock off one time and washed and rinsed it with sanitized water. I put it back on, and within 30 seconds here is what I saw!

Is this something that I should consider to be normal, and if so what should I do? Just let it run, or should I try to clean the airlock periodically? I am using a 5 gallon bucket as my primary fermenter without a blow-off tube, and this is within about 24 hours of being placed into the primary.

Thanks for the help everyone!

you need to put a blow off tube on. take the bubbler cap out and put a hose on the stem of the airlock and run it into a jar of sanitizer

It happens. The real fun begins once the hole gets plugged up. Then the pressure builds and eventually your lid violently pops off and makes a big mess.

Congrats! You have good fermentation going on which is very good...Now you need to follow the above advice...get 1/2 inch or 5/8 inch tubing and connect it to the airlock and put the other end below the carboy into a jar of sanitizer....

Ok, thanks for the help! I have taken your suggestions and added a blow-off tube.

Is this just needed because an airlock can't keep up with the quick fermentation at the beginning?

it's not the airlock,it's the lack of head space in the fermenter combined with an extra vigorous fermentation.

Does anyone else use 5 gallon buckets for primary?

I have read numerous places where people have used them. This is my 4th batch using them as both primary and secondary without any problems. Although this is my first batch with this vigorous of a primary fermentation! :-P

If you're doing a 5 gallon batch, a 5-gallon bucket is a little small for a primary fermenter. My primary holds about 7.5 gallons, and I've never needed a blowoff tube.

I use a 6.5 gal bucket for primary (to cheap to by a carboy yet) to prevent the issue of the little hole in the airlock getting blocked when using a blowoff tube, I just put the tube into the grommit where the air lock goes. Its a tight fit but it works.
