I have an amber ale I am fixin to keg. And the same day going to make a Wee Heavy. People talk about reusing yeast but I have never done this. After I transfer my amber to the keg, do I need to pour the yeast into a sanitized container and then pour back in the fermenter for the Wee heavy? Do I pour it in the bottom before I transfer the wort to the fermenter? Or should I oxygenate the wort first then pour the yeast in the fermenter? Or do you just transfer the wee heavy in the fermenter without cleaning? What about all the crap stuck to the walls? Normally this beer takes 2 pkgs of yeast. Will I still need 2 or will 1 be enough. Help!
