I have let my flame-out hops simmer for 20 minutes or so in the boil kettle after turning the burner off, to extract as much hop flavor as I can before chilling the beer with an imersion chiller. I would like to whirlpool as well on my next batch, but am concerned that if I whirlpool while my flame-out hops settle, I will disturb the sediment created by the whirlpool when I drop my coil chiller in after 20 mins or so. How do others use a coil chiller, create a whirlpool, and allow flame-out hops to do their thing without disturbing the sediment, or let things sit too long prior to chilling. I have always been told to chill the beer down ASAP after the boil.
