OK, sorry, but I too did not understand all of your questions. But the one I got was about your FG (final gravity) When your gravity readings are constant for a week or more, then fermentation is complete. At that point you can bottle, or keg, or whatever you want to do with it.
I don't keg, so I can't answer your other questions.
Meads: Hababero and Sarrano Capiscumel, Show Mead possibly getting split and flavored, and 12 gallons of Bochet Deliciousness
