Av og til kan lodo-bryggere virke litt nyreligiøse. På desperat leting etter argumenter for at det de driver med er riktig, lite lydhøre for motargumenter og veldig opptatt av å fortelle andre at de tar feil. Selv om lodo har noe for seg, så blir det litt vanskelig å ta det seriøst når alle kritiske spørsmål sables ned med at man tar feil.
Ja, det er fare for confirmation bias, spesielt for de som har brukt mye tid og penger på det, selv om noe som blir sagt er litt spøkefull tone "himmelen åpnet seg og englene begynte å synge". Men støtte i teori og praksis virker solid. For min del er det interessant å utforske videre, gjør det meste rett på de fleste områder ( bortsett bl.a. fra at jeg ikke har fat), og tenker kanskje dette kan utgjøre en liten forskjell.
Det er en del folk som har gode erfaringer etterhvert. Her er en test som ble delt på tråden jeg linket til over:
Introduction to Low Oxygen Brewing
"Gonna reluctantly post a triangle test I did today on the Dunkels I brewed on 12/28. Please take it as it's intended, as a single data point. No broad pronouncement or indictment of anyone here, or how they choose to brew. Couldn't care less. Really.
Here is the triangle test. Finally got the group of friends I wanted all in the same room, no small feat. The idea was to have mostly brewers with a few non brewers, to show applicability across a wider group of people. 8 people total, 6 good brewers, 2 wine and craft beer fanatics with good palates. This is only intended to show tasting preference, not to rise to laboratory paper level.
I brewed 2 dunkels on 12/28, one my traditional method (Narziss style temp rise @ 60% attenuation), the other low O2 style (46 F held throughout), in addition to the other stated methods. I was diligent and lucky, and achieved 1.052 OG on both, 1.010 FG on both. Same grist (double weighed), strain (2206), mash pH (5.2), and step schedule. The low O2 beer is noticeably lighter in color, so I used opaque cups to avoid any presumed prejudice. I will post a pic soon, as the one I took today didn't do justice to the difference (it was cloudy outside).
Results:
Of the 8 people, 6 could tell a difference between the samples (one brewer, one non brewer could not).
Of the 6 people who noticed a difference, 5 preferred the low O2 Dunkel.
Comments from the people who preferred the low O2 beer:
"Amazing malt aroma and flavor".
"Better malt character and softer character".
"Great malt character and drinkability".
"More defined malt. Great malt aroma".
"Better beer. Softer, more drinkable. Awesome malt character".
Just a data point. Both are good beers. My prior assessment was that the low O2 is far better. Nothing changes my feeling there. Only $0.02 .
