I'm going to be attempting to make the Zombie Dust clone listed on the site here in a few weeks and it requires a first wort hop addition. Since this is my first time trying this technique I really don't want to screw it up. I know I leave the muslin bag of hops in the kettle while I collect the wort from sparging but do I leave the bag in for the full 60 minute boil or do I take it out after I have my full boil volume? I've heard Citra can get kinda sideways flavorwise when it's used as a bittering hop so I wasn't sure if I need to leave it in there the whole time.
