Fermenting in Corny Kegs
« on: August 15, 2020, 05:54:27 pm »
I've just a few questions for those who are or may have done this. So, I've been looking at getting away from my carboys this year and was going to buy a SS Brew Bucket or two but then I looked over that Brülosophy article talking about just using a Corny. Thought about giving it a try and seeing what I thought. Though, this lead to a few questions..

1. How much yeast & trub could be estimated? In the article, they said to cut an inch off the dip tube but I feel like it would need more than that... And the pic looked like more... But who knows.

2. I have Tilts, so can it be read through the keg just fine? I heard it can read through the buckets fine and I don't expect it to be that different but curious if anyone has done it.

3. Did you make any other modifications to the keg or just cut the dip tube? I saw some say they altered the gas out post but I didn't understand what they did or why.

4. I feel like I had a fourth but can't think of it... Oh well.. I'm sure it'll come back to me if it was really there.

Cheers!

I've ben leaving my dip tube as-is and blowing the trub out under pressure. It works fine most of the time, but can clog up with a lot of dry hops or a chunky yeast like WLP002.

I recently got a floating dip tube that I plan to install before my next brew that should eliminate the clogged dip tube issue. I plan to set it up so it stops about an inch above the bottom to start, knowing I can easily trim it back more if needed.

Sounds like you're serving in the same keg? I planned to transfer out of it. Keep the cycle going and have back up kegs.

No, I transfer. But the floating dip tube will ensure that I transfer clear beer to my serving keg.

Ah, ok. That makes total sense. Can pull until the very last of the clear without worrying about it.

Don't worry about cutting the diptube.  You can always slip a piece of vinyl tubing over it if you need to extend it.  I cut an inch off mine and that seems about right.  Keep in mind that if you ferment in a 5 gal. corny you'll have to limit batch size to 3.5-4 gal.  Drew and I both use 10 gal. cornies.  You can ferment an 8 gal. batch in one of those.

I'm going to try fermenting in cornies. Split a 10+ gallon batch into 3 cornies, by weight. After fermentation transfer to 2 fresh purged cornies.

Splitting, that's not a bad idea.. I was just going to drop my batch size.. maybe depending on the beer I am going to do. My new kegs should show up Wednesday.. I should be able to whip some beers up after that. See what happens.. see if my Tilts read.

FWIW, I ferment in a 16 gallon converted keg with a corny lid welded in and I have no problem getting Tilt readings to a iPod on the edge of my chest freezer.  I set the iPad just enough in the lid to hold it and I get readings just fine. 

I like the idea of a floating dip tube.  Do you install it prior the start of fermentation or wait until the end?  I wondered about Krausen if installed in the beginning, but more oxygen if installed right before transfer.

I ferment in a 13 gallon kegmenter with Tilt and floating dip tube.  Works great and I have experienced no hanging up between the two while in the vessel.

I have a Tilt, and it works fine from inside of a 10 gallon corny keg.  However, I can't get a reading though the lid of the chest freezer that I use as a fermentation chamber.

That's something I was "worried" about. In my carboys it reads reads just fine in my chest freezer from about 5 feet away.. hmm..

Question 4: Do I need to do anything fancy to cold crash? I have a CO2 collection device that I use and connect when I crash in my carboy.. I could just disconnect my out and not worry at all.. right? Or would that lead to issues..
