I am wondering if we listened to the same video you posted? I heard him say he would put his investment in low O2 packaging and keeping beer cold before he would brewhaus oxidation. The fact that there’s yeast in the beer protects it from aging characteristics and O2 pickup. Pretty much the same consistent message he’s been delivering over the last few years as far as I know. Maybe I missed something.
Maybe not. This is what he said exactly, with the possible exception of one or two stutters:
"Hot side aeration.. like I say, I’m not saying that air pick up in a brewhouse is not significant, I’m not saying that it’s insignificant, but you know that all comes before the yeast, and yeast is a great friend to the brewer because not only can yeast mop up oxygen it can also mop up a lot of the carbonyl compounds which contribute to aging. So if your yeast is healthy and your yeast is being looked after and reused properly it can do an awful lot of good. And you know I’m associated with Sierra Nevada these days and you know, natural conditioning, having yeast at the bottom of the bottle is a very valuable thing to have there because it’s mopping up oxygen it’s mopping up age character. So um, so I, I agree with what Jens has said, there is a lot, there is very complicated thing, but, but if I was to invest, let’s put it this way Doug, if I was to invest my money in best possible packaging equipment and refrigerated distribution, I would spend my money there before I would spend it on minimizing oxygen uptake in the brewhouse."
So lets recap: HSA is not insignificant. Yeast can help. Fix your cold side before wasting money on the hot.
Since my cold side is stellar (keg spunding in ferment CO2 purged kegs with all buna-n seals, stored cold) and my distribution channels are short (ferment refrigerator located 6 inches from lagering chamber that is a further 12 inches from the serving fridge) I feel pretty good that I have satisfied his conditions and that moving toward eliminating or reducing the hot side oxygen was the correct next step.
