If it really does make a difference when you do it "whole hog" as you say, I don't see why it wouldn't if you went 3/4 hog and tried as hard as possible to reduce O2 pickup. Like I've said, it can't hurt. I'm always looking for way to improve my beers, I'm not set in my ways like Denny! (that's a friendly wink, not an a$$hole wink, by the way).I don't necessarily agree with this. Chemical reactions are based on time, temperature and concentration - they aren't instant. If this is indeed a reproducible result, then there has to be some point below the maximum effect where it is just enough to cross the flavor threshold.I'm open to the idea and likely will not adhere to every step but just try to reduce the O2 pickup anywhere I can.
That's the crux of it though, you can't simply "pick and choose" where to limit the O2 pickup - you either go whole hog or you fail to effectively test the process. If at any point, you pick up too high ppm of dissolved oxygen then you immediately run the risk of "ruined" results and your end product cannot be used for evaluation of the idea proposed in the PDF. I'm not trying to dissuade, or agree/disagree with any one in particular; I'm just saying, don't do it half-assed. It's like rebuilding a vintage car; do it right or don't do it at all.
You may well be correct - certainly that the reactions are not instant, you are. I've only read the article once through, but my recollection was that the levels at which dissolved oxygen is suggested to remain below was exceptionally low (<1ppm I think) throughout the majority of the warm-side process. They even provided an example of some basic techniques us "american" brewers tend to use that immediately put us well above that threshold; not to mention all the stirring, pouring, splashing, metal-use, etc that only increases the oxidative factor. All this said, I just can't see how someone could proceed to reproduce the PDF's process without going "whole hog" - it just seems a disservice otherwise - all opinion of course.
If I had the means/facilities/etc to get close to the suggested procedure I would give it a shot, but I'm too far off on too many bases to have the results prove meaningful.
