Corny Kegs for fermentation?
January 17, 2010 - 9:39pm
I've been reading up on the homebrewing forums about using a corny to ferment in, instead of a glass carboy or bucket. Has anyone done this? I've used Garry's converted sanke fermenter, and from the pictures of the corny version, it would be very cheap to convert. Plus you can still go back and use for kegging. I'd rather not break another glass one (1 time was enough) and I've read how you can push the wort out into a 2ndary fermentor without any risk of oxygen getting in. Plus you can push it again into the final keg the same way. The down side I saw was with head space, but with antifoam, that shouldn't be a problem.
This site even shows pictures of different options (I liked the last picture instead of the lid ones)

I know a few people that do it, but its always with blow off tubes not airlocks. You can't ferment 5 gallons of beer in a 5 gallon corny and expect to not have a big mess. The anti foam stuff helps but if you have good healthy yeast eating you beers nothing I have been able to do prevents a blow off even with a 6.5gal corny. Of course this is with 12% beers... so YRMV.

Never thought to use our Cornys for fermenting, mainly because we have 3 Conicals.

Thats how we roll. :)
We use corny's for pilot batches all the time at the brewery. You'll need to split the batch (assuming 5 gal) in to two cornys to ferment. There are some other specifics too, but it works well.
