I was reading about conditioning in the keg, then when you're ready to serve you would rack from that keg into a new one in order to leave more of the sediment behind. Is this a good idea? Would you do this if you are using a carboy secondary, or is this like using the keg as a secondary? What kind of siphoning device would you use - an extra long racking cane? Could you use an auto siphon? Thanks!
