It was a long brew day today, but I got a double batch of Dunkel in. The first was done my old traditional way, (ie., Narziss style ramped up fermentation schedule) with a copper chiller, where the second was done low O2 - trifecta (SMB/AA/BTB) in mash, mash cap, reduced evaporation, SS chiller, and will be fermented cool with no ramp. Same exact grist, same strain (2206), same mash pH, and both hit exactly 1.052 OG which is huge since I brewed these for comparison. The former will be force carbed, the latter spunded. Plans are to do a triangle and get some solid feedback. The tasters will be brewer friends with good palates. Looking forward to seeing the results, whatever they are. Pics and results to come.
Edit - I'll say that the wort samples were markedly different. The low O2 wort had far more malt complexity and depth. As that applies to the final beers and my comrades opinions, we'll see.
