Transferring from a corny keg fermenter w/o trub
« on: August 29, 2017, 03:16:30 AM »
I have been fermenting in a 5 gallon pin lock keg the last few batches. I brew 3 gallon batches, so, the size is perfect. I use a spunding valve to naturally carbonate the beer and then transfer under pressure to a sani-purged keg.

I tried using a cut dip tube. That worked okay, but, I also have tried   using a Clear Beer Draft System (http://www.clearbeerdraughtsystem.com/) in the fermenter. The clear beer draught system works well for this application.

Here a couple of pics stolen from Clear Beer's website.


The float keeps the beer inlet above any trub. The float is in the fermenter from day one. I was worried it might get clogged by krausen, but, so far that hasn't been a problem.


The float is stainless steel.

PS. I forgot to set the subforum for this post. It ended up in the same subforum as my previous post. Sorry.

 That's some quality MS Paint art there. I know a few people that use these for dispensing, but hadn't heard about it for fermenting beer. No issue with krausen?

No krausen issues for the 2 lagers I tried. Both with the same yeast. If it gets stuck, I can try extra pressure to unstick.

If that doesn't work, I can put the original dip tip back in without too much fuss, I think (some oxygen exposure though).

I've been thinking of fermenting in kegs. I've got two taps, 4 5-gallon ball-lock kegs and 2 3-gallon pinlocks. Are you serving your 3 gallon batches in 5-gallon kegs? I suppose if you are voiding oxygen as best you can, the smaller batch size to keg shouldn't be an issue.

I used the clear beer system to dispense. Never thought of using it to ferment.

No. I have 2.5 gallon kegs. The extra half gallon is mostly trub.

I fill the kegs all the way with starsan then empty by pushing co2. This gets nearly all oxygen out of the keg.

I have a buddy who does the same thing with a ping pong ball and some zip ties.

Beer is like porn. You can buy it, but it's more fun to make your own.

I have three things that can go inside my kegs. (1) Ball and Keg to monitor the beer remaining, (2) the clear beer draught system, (3) a stainless dry hop container.

It seems these items are not 100% compatible with one another. I could not get the ball and keg magnet to stick when the clear beer was inside the keg. I am guessing the inside magnet of the ball and keg was sticking to the clear beer floater.

Then at one point with about 3/4 gallon remaining the clear beer somehow got stuck (I think the dry hopper got in the way) and stopped serving beer. I had to open the keg and knock it free.

For my current brew, I only have one of the three in the keg; the clear beer. I am pretty sure the clear beer has no real value when serving. My beer took about the same amount of time to clear. I am glad I bought it for the fermenting keg transfer not for serving.

That's a real shame because is sure makes sense that it should result in clearer pours much earlier on in a kegs life.  This is the first time I read that it doesn't result in clearer beer.  You're not spunding or keg priming are you?

Clear beer system now has a screen.  I was able to throw three ounces in the keg without clogging or getting hop bits in my beer
Some day we'll look back on this and it will all seem funny

I spund then transfer to a keg with the method described in my original post.  I generally have clear beer about two weeks after kegging for lagers.

My observation is just a comparison of two batches. I brewed a German Pils and my SABL clone both with same yeast. I kegged both after two weeks in the fermenter. Both were clear two weeks later. One used the Clear Beer system and one used a dip tube. YMMV. Things may be different for different yeast and other situations.

That's a good use for the screen. I don't have the screen. I have stainless screen container. The Clear Beer screen is probably better.

Good info.  I've been eyeing the clear beer system but this is going to slow me down for sure.  I'll let it keep playing out for now I guess.  Thanks for your feedback on this.
