Give me the jist on whirlpooling for hop flavor

[noslenwerd]

Something else I haven't really seen discussed much... Any hops you add to the boil - in my case I am adding 2oz at 15 min - will also be giving off more IBUs during a whirlpool/hop stand as well?

I would think 2oz isn't enough to really give a ton of bitterness through the whirlpool/hop stand, but I would still be curious to find out the mechanics behind that... you know, for science!

I believe that's a yes. If I recall correctly, most of the Brulosopher's experiments use hop socks for carefully controlling this factor.

I see no reason why those 15min additions would not be adding bitterness during the hopstand. To try and better control my IBU for this brew i used a hop spider and pulled the bittering additions out when I cut the flame and prepped for the whirlpool.

Moment of hilarity: my first-ever hopstand attempt, I finish the boil, then set the kettle in the cooling bath (per usual procedure). Hmm, I thinks to myself, I'd say about fifteen minutes would be the first time to check the temperature... I was guessing it'd still be super hot at that point as I usually leave the kettle in the bath for 75 minutes before pouring into the fermeter.

Yeah... so... after only fifteen minutes the temperature was already down below 140. Crap.

Well, maybe next time?

Some people wait till 140 to add the hop stands.
