Keg to keg transfer

[windrider]

Need to transfer some carbonated beer from my 19L keg to my 9L corny.

First time doing this and I’ve read lots of articles and understand the procedure. Most people say to reduce the pressure in the source keg so it’s just enough to force the beer out and keep pulling the PRV valve on the destination keg.

Could I not just have the source keg higher than the destination keg, split the CO2 line so both kegs are at the same pressure and pull the PRV and let gravity take care of the rest? I’m thinking if the kegs are at the same pressure then I shouldn’t get any foaming issues?

Any thoughts?

I think you need to have the destination one a bit lower or the beer doesn't move. I may be wrong!

That was the way I used to do it.

Source keg higher than lower and a pair of 'Jumper' lines (Black to Black , Grey To Grey)

Connect Gas In To Gas In . . . and the pressures equalise

Connect Beer Out on the receiving keg to Beer out on the Source keg.

Temporarily remove the grey disco from the destination keg and lift the PRV to start the 'Syphon', once beer is flowing close the PRV and reconnect the Grey Disco.

Beer is transferred by syphon in a closed loop. and as it's all at the same pressure foaming is minimal or non existent.

That sounds like a great way of doing it. I've never done it like that as I haven't got a gas line to gas line jumper made up.

That's an even simpler method I was thinking of I was just going to split the gas line with a JG Y splitter and connect to both kegs

Going to try it tonight, I will let you know how I get on.

Hi all,

I tried the closed transfer using the double jumper method in this thread. It all seemed to go well but one the beer had stopped flowing I opened up the source keg to find about a litre of beer remained. Is this usual using this method?

Cheers

You did well getting 19lt into a 9lt keg. The last liter was due to the equalisation of pressure between the kegs.

[danwlx]

Thanks Bob, would opening the prv on the destination keg move the last litre or so?

[Aleman]

It would, but remember to lift the grey disco on the receiving keg as well otherwise you release the pressure in both kegs equally.

I must say that I've always had no issues transferring all the beer from one to the other . . . in fact I often end up transferring the sediment that I was trying to leave behind . . .mainly due to inattention

[Scratching my head] I use one 'jumper' (black to black).
Step 1 connect gas to receiving keg and pressurise to about 3psi.
Step 2 vent supplying keg and repressurise to about 3psi (leave gas connected here).
Step 3 connect jumper to supplying keg.
Step 4 connect jumper to receiving keg.
Then vent receiving keg periodically to manage the flow.

Don't get too greedy, like Aleman
