Personally, I dislike the interaction you can get between yeast and hops and always remove the beer from the yeast before dry hopping.
Denny or someone, refresh me on the science here... why is it that biotransformation only happens to hop oils introduced as a part of the dry hop and not what we add in a 160F hop stand? Nobody complains about, or seeks out, biotransformation of their whirlpool addidtions. Why not?
Right but the oils introduced during the whirlpool, upon which the yeast work/transform, should should be there when the yeast become active, no?

The biotransformation happens between active yeast and hops. Obviously no active yeast in the whirlpool.

Sure, they would. I assume not in the concentrated , non-volatilized form as would be present in dry hopping. Not a brewing scientist, just a WAG.

Yeah, weird floral flavors and aromas.

So, if I want weird floral flavor and aroma I should dry hop in primary. A new technique, thanks Denny.  ;D
I like the flowery and perfumey aromas that you get when dry hopping on the yeast, and I also dry hop once the yeast drop.
