Just upgraded to 10 gallon batches and have my finished beer in 2 cornies. I have the gas line on one keg in the in port and the out port of that same keg is connected to the in of the other keg. Will the gas carbonate both kegs? Or should I treat them on there own? My thinking is that the keg that is gassed will absorb till saturated then the excess gas will transfer to the other keg. Other thoughts?
