I have a brown ale recipe that I’m looking to brew this weekend. There is a 30 minute hop addition and a 25 minute whirlpool addition. It originally uses Columbus for both. I do not have so I’m going to substitute Chinook.
For the 30 minute addition I plan on adjusting to the amount to maintain similar AAU.
My question is about the whirlpool substitution. Should I aim to maintain AAU or amount or somewhere in the middle?
Thanks ,
Tommy
I guess my question would be what temp whirlpool?
I mean if we’re talking flame out, add hops, and whirlpool at 190-200*F, then I imagine you’re looking for the bitterness (because you’ll drive off the oils) so I’d account for the bittering.
But if you cool the wort to say 160*F or so, then adding hops and whirlpooling, I think bittering is not the point — it’s the oils you’re attempting to preserve. Even though I imagine some hops have more oils than others, at that point I’d match weight for weight.
Add at flameout and whirlpool for 25 minutes.
I generally see temp drop to about 185 over that time.
Sounds like I should be looking to maintain AAU.
