I just kicked a keg of a NEIPA I created and conveniently I have another 5 gallons of the identical beer that just finished fermentation and is ready to keg. I usually do closed transfers from my glass fermenter to my kegs but I am contemplating just opening the kicked keg and refilling it with standard auto siphon for ease. I realize the disadvantages of using auto siphon vs closed transfer and am not concerned about that. My question is whether anybody else ever simply refills a keg with same beer in a "used" keg without cleaning and sanitizing it? I imagine that works just fine??
