I have a five gallon batch of a black IPA (recipe kit) in a five gallon plastic big mouth bubbler. Per the recipe instructions I added hop pellets from the kit about a week after transferring to the secondary. Unfortunately a frothy hop slurry is just floating on the top and has not settled after three days. Can I gently swirl or agitate the fermenter to get it to settle? I purged the secondary with CO2 before racking from the primary and also purged the head space again before I put the lid and airlock on. The secondary is in a temp controlled deep freezer being held at 65 degrees. Should I just be patient and wait see if the froth settles? Is it possible the froth is actually krausen resulting from additional fermentation after the addition of the hops pellets? I normally would not have transferred to a secondary, but the recipe instructions called for secondary conditioning and did not indicate as an “optional” step. Any suggestions appreciated.
