Confused by first wort hopping

[sbond10]

I understand FWH to be used instead of your normal bittering addition at 90 mins but I'm a little confused reading around suggests it's your aroma hops that are used for this technique. So I'm a little puzzled anyone shed any l8ght or advice on this subject or is it not worth it

I think this subject confuses even the most scientific of expert brewers.
The hop addition is for aroma you would think that the aroma would be boiled off but I've done comparisons and it works.
The only explenation I've read is that somehow because of the higher PH of the first running the aroma becomes attached to the beer structure and isn't boiled away ....I know it sounds like mumbo jumbo but it certainly works.

Here is a rather succinct write up from BYO magazine on the subject.

That's the article that confused the hell out of me. So if I had a recipe that looks like this

90 mins admiral
15 mins Willamette
0 mins Willamette

How would I adjust this

[alix101]

Just add the admiral straight to the kettle with your first runnings.leave the other additions where they are.

Brulosophy tested FWH and it didn't really make any difference http://brulosophy.com/2015/07/06/the-fi ... t-results/

All ‘exbeerments’ are fatally flawed, unfortunately.

How did the constipated statistician work it out?

Ermmmm!!! Not saying I don't believe you, necessarily, but would you care to elaborate as to why? The only problem I have with his conclusions is that the sample size is invariably rather small.

With a sharp pencil.

It's not used instead of the bittering charge.

No, a lolly stick.

How do you know the result of an ‘xbmt’ isn't simply down to random chance? What if they dared to replicate an ‘xbmt’? It’s not acceptable to interpret any result from one test sample. That’s not an experiment. It’s a form of hoodwinking. Are these guys trying to refute brewing scientists, who’ve actually designed experiments? Every time I read ‘brulosophy’ on a home brew forum, I sigh and mutter a string of expletives.

All my bittering hops are first wort hops as it helps stop boil overs. There's certainly no lack of bittering or any extra flavour I get from it. ymmv

You don't, it's hardly five sigma but at least someone's willing to give it a go!

Why don't we all?!

Really? I don't think they are trying to hoodwink, they're just brewing beer and asking for opinions.

I just thought some form of experiment on the theory might of been of interest.
