Howdy,
I use ~75% Pilsner in my brews (belgians). I have a jamil-o-chiller and would like to whirlpool FO addition.
I have had bad DMS experience with leaving the lid tight at FO and letting the wort sit before I start cooling. I now just cover the pot with the lid cracked and cool immediatly.
So I plan to add hops at FO and whirlpool starting the chill immediately (it takes ~15min to 140F) with the lid cracked. See any issues with loss of aromatics and can you use less hops than just a straight FO and no whirlpool.
-Cheers
