Corny fermenter airlock
1 Attachment(s)
Having recently bought a 10 gallon corny keg for real cheap on craigslist I wanted to ferment in it. It'd work great for this purpose with sealed transfers and other benefits such as no glass. But the only challenge was getting an airlock on it.

The solution? A piece of CO2 line hose,quick disconnect,wire and an airlock. It doesn't get much simpler but it works fine.

Pretty ingenious rig you got there.

You might want to try http://kegpasties.com/ if you have more.

It's a one piece silicone plug that is designed to fit over the has in post and let you put in a airlock. It will cut down on how much height is needed.

How to Use:
1. Unscrew the “In” nipple of your Cornelius® keg
2. Remove the “poppet” valve from the nipple
3. Screw the nipple back on to the keg.
4. Slide the large end of a clean Keg Pasty over the nipple*
5. Push a clean air lock in to the Keg Pasty

I want a 10 gallon corny. I never see those for cheap.

I like the pasties. I wonder how much I would have to trim off the dip tube to avoid the yeast cake? With a pastie and a shortened dip tube, any keg would work as a secondary for lagers. Cornies fit the fridge better than even 5 gallon better bottles.

as far as the foam cake midwest has a kit that is currently unavailiable like this. They mention a product that keeps the foam down. Maby someone can interject. its called Fermcap-S foam control.

Oh one word of warning about using corny kegs for fermentation. Make sure you put the airlock on the IN post. I made the mistake once of putting it on the out post. It only dripped a little bit of beer on a tile floor since I caught it soon. But could be pretty bad if you let it go the whole time.

Sure Screen from notherern brewer- I've experimented on some batches, and this is by far the best I found. It is a stainless steel screen about 6 inches long that you put on the dip tube (no cutting or bending required, although it does bend a little when you tighten the post). I ferment in corny, blow off tube on the IN side as noted above. I normally let it go for a month(ish) so I don't bother cold breaking. If you don't let it go that long, you might want to, haven't experimented. I then pressurize a sanitized corny to about 30PSI, pressurize brew to about 30PSI, jumper the out to out, and bleed my brew into the new keg for carbing and conditioning. Clear beer with no oxidation, plus no subjection to light etc.
