Still brewing related.
I ferment in carboys and use it to force rack to another carboy or keg. Eliminates lifting full carboys up to use gravity to rack. My beer never sees oxygen. You must do this w/ caution because carboys are not designed for pressure. Be sure to purge the receiving vessel w/CO2. I use only enough pressure to get the beer moving( a lb or two, hardly even registers on the gauge) and it usually takes 10-15 mins for transfer. What's the rush?
You probably already have the equipment: 2 racking canes, tubing, carboy cap, and a barbed connector to connect the gas line to the carboy cap.
