The problem with that hypothesis is that FWH doesn't add aroma, as far as I or any of the tasters in my experiment can tell.In the link DJ posted it mentions pH having a factor at the preboil stage in isomerization for bitterness, but dosnt mention much about the "why" for aroma. From what I have seen, the aroma comes from oils in the hop's glands that are volatile at boil temperatures. So very little oils are extracted when the addition is added at boiltime, and what is extracted usually vaporizes. The FWH allows these oils to be extracted in a much higher volume due to optimum temperature, so even though some boil off occurs, much oil is left behind, producing aroma. The other way for extracting besides these optimum temps is the more obvious dryhop, and that gets its success because now alcohol is involved which aids in the stripping of these oils during the secondary/keg period. The third alternative is to filter through the hopback, but to get optimum results you would want to chill the wort to 150-160 before doing so, which is ideal. That is at least what I have learned so far.
FWH'ing the first time....

I get aroma contribution from FWH, but on an inconsistent basis. Why, I have no idea because my routine is the same every time. The first thing in the kettle is hops, fly sparge and flip the switch once the element is covered. Maybe it's the type of hops because I've used at least 12+ different hops doing this.The problem with that hypothesis is that FWH doesn't add aroma, as far as I or any of the tasters in my experiment can tell.

Well, if he posted here, he could answer us.Denny, You have to get on his case about resolving his membership here.I respectfully disagree wit John on this. I wonder how much batch sparging he's actually done?
