i want to share a method with you all that I have been using since before I hurt my back but has since become a necesity. The benefit of this is that you are transfering under pressure and are purging your kegs of ambient air.
I just finished keggin my two beers today that I brewed with the same batch and split into separate fermentors and pitched different yeast. That post https://www.homebrewersassociation.org/forum/index.php?topic=31273.0
So basically i cant take claim of this idea as we used it at the brewery I worked for to transfer to and from barrels. We called it the bullpup.
A close up of the stopper. I used a #7 solid stopper and drilled hole in it to fit a SS racking cane and an old SS filling tube from a maheen.
I fill my kegs up with sani and then push the sani with CO2 out through the bullpup into a bucket and allow it to sit for a few minutes and then drop the cane into the carboy and push the beer out with CO2. I use only 5 - 6 psig to prevent the carboy from exploding in case some trub clogs the hose.
Every thing is conveniently located on the floor and I do not have to lift items up onto counters
I am trying to adapt this idea to work with a bottling bucket in for when I decide to do some bottle conditioned beers.
