There’s an option missing that‘s going to promote massive bias. ‘None’ = ‘I don’t consciously implement any prescribed practices to limit so-called HSA. Pretending that’s not what this thread’s about just makes it a little bit more funny. Little more than a preconceived survey pushing its agenda. I‘m very happy with my beers, including my lagers. I can only assume someone somewhere is making money out of this tosh. Therefore I’d like to know how much home brewers subscribed to LODO spend on practicing what they preach. Even surveys need to be carefully designed, to be meaningful and represent a snapshot of averaged reality. Unless someone’s trying to sell something, of course.
We all know who you are and how you feel.
Some, perhaps most, even agree with you. Even I agree with you on most points but railing against it doesn't make it go away.
Some of the comments and the survey itself even lean towards your bent.
The only reason there isn't a '
None' option is because only 10 items are allowed on a survey (couldn't find a way to add more).
I think the comment about no dedicated book having been written on the subject speaks volumes:
1.) The knowledge is locked up in textbooks and science papers out-of-reach to the common homebrewer
2.) It requires a "high degree" of scientific (chemistry) knowledge to condense what is known into something readable for the homebrewer
3.) The benefits of such a process are difficult to quantify on a small scale
4.) The industry knows best practices (macro beer producers and chemical makers, BTB, Antioxin SBT etc...) and has invested the money to figure it out but that's because it gives them a return on their investment.
The LODO group and their webpage have summarized as best they could their processes learned from textbooks and their own experiments.
Still a down-to-earth treatment of the subject in a published book would require some heavy lifting but would certainly educate and put an end to much of the misinformation that has been generated.
As far as capitalizing on it... I'm not sure, it (the process) seems to be misunderstood by most (especially with home based experiments propagating misinformation) and really there are only two companies that have taken it to a "good enough" level with the help of the individual who first raised the issue. Stout Tanks low oxygen and Speidel Braumeister low oxygen kit. Both of which are expensive pieces of kit which most can't afford.
The problem with the money thing is that it has to be a complete system in order to realize the raison d'être of the process. Selling mash caps and chemicals based on these concepts probably doesn't generate a lot of revenue.
