Maximizing my Corny keg volume
« on: January 09, 2015, 09:21:09 PM »
I haven't really had much love for my corny kegs due to them only having a volume of just over 18L, of course which always results in bottling a few bottles at the end of my carboy. So after a bit of searching I found that its pretty common for people to shorten their gas post so they can fit more beer in the keg. Today I did just that, was able to fit nearly a full 20L into my corny. Just used a simple pipe cutting tool and took my time and cut it off shorter. After I cut it off, I used a rifle brass deburring tool to take off the sharp edges and debris left over from the cut. Worked well, so thought I would share for anybody else that may want to do the same.

hey thanks for posting that, very timely for me. I just filled my first keg on the weekend and was wondering if I could cut that tube off a bit. I'll do just that next time I fill it.

My approach would be to typically fill above the gas post and hope for the best.

Heh heh - yes mine as well. Last time I did that though, I had 30psi in the keg. I then connected a 10psi line to it, and since the level of the beer was higher than the gas dip tube, beer went back into my regulator. I was soooo happy... the air turned blue for a minute or two... :shakes:

Haha...yeah I hear ya there brew, same with me. Was getting tired of beer going back through my gas line doing force carbs. If you are setup so this won't happen its probably not a big deal, but I have some T's in my line.

Yeah, that happened to me as well. No liquid in the regulator but there was beer in my gas line and it took me a while to figure out that the gas line was dirty with moldy beer. Then I decided to change the gas lines. I was annoyed.  :(

I have done this more times than I can count. The only issue is to make sure the pressure feeding the keg is equal to or greater than the pressure in the keg, or better yet, put a check valve on the gas line. On one occasion, prior to having a check valve, I did get a geyser of beer going backwards through the regulator vent, but, follow the above, and there is nothing to worry about.
