When I read his articles I am really taking everything with a grain of salt. He seems to be coming from the standpoint of trying to translate what German breweries are doing in their production and applying it to homebrew scales. I don’t think that Weihenstephan’s experience with FWH necessarily applies to my APA’s.
I take advice that has been extrapolated from the practice of large breweries with a grain of salt, because things just don’t always scale to homebrew practice well. We have a lot more freedom because our primary endpoint is almost solely quality-focused, rather than economic.
I’d say the endpoint of homebrewing is “enjoyment” rather than quality. “Expectation effects” have a huge impact on perceived enjoyment. If you FWH and you’re convinced it makes your beer better, you will perceive beers you FWH to be better. We all want to be right and we want to confirm our biases. Since beer is so subjective and we’re so invested in the beer we make, it’s really easy to enjoy the beer we make. This is why no one makes “bad” homebrew.
I really like that guy’s articles and I agree with most of what he says. FWH doesn’t make a tremendous difference in quality (if any) but it does require hops, which cost money. Even if FWH does make a slightly better beer, on an industrial scale it’d be better to omit and save the money.
+1 here. The only thing I would add is the 30 minute hop addition makes it different than the 20 minute, 10 minute, whirlpool, etc… How do you know whether you like it or not until you try it? Brew the same APA with a 30 minute instead of a 10 minute addition and compare them side by side. That’s the great part of this hobby for me, the experimentation.
I make beer because I really really like beer. No one has more potential to make a beer I will enjoy more than I do. Making the most enjoyable beer I can is my drive.
I think there’s flavor infused through a 30min hop addition, but most if not all of the volatile oils that aide in aroma are boiled off. I think the aroma/flavor ratio decreases as the amount of time the hops are exposed to the boiling wort increases. In other words, hop aroma increases and hop flavor decreases as the hops spend less time in the boiling wort and visa-versa.
I also think a very strong dank hop aroma can enhance the perceived intensity of hop flavor. This is the aroma that can be achieved by large flame out and dry hop additions.
Of course, this is not reasonably scientific but based on my experiences.
