Planning to try dry hopping in a keg. Going to add pellet hops loose and purge the keg. Do a closed transfer after cool crashing 2 days at 55. Let the keg sit a day at 55, cold crash 2 days at 33 then close transfer to a serving keg. My question is how much should I trim off the dip tube? If the popet does clog what is the best way to clear it without letting oxygen in? How does the dry hop plan sound? Going to be a 5 gallon batch of NEIPA with 6-8 oz dry hops.
