Thanks to Marcus Schmitz for going to the trouble to transcribe these from a handwritten laboratory manual of 1936 by a former Engelhardt-Brauerei Brewmaster.
What's particularly pleasing is that there are examples from both Poland and Germany. In fact, the examples are from all the breweries brewing Grätzer/Grodziskie after WW I. Which was one in Poland and two in Berlin.
Unfortunately, there was no measurement of the level of acidity. Probably the detail that I would most have liked to see. I really want to kill the myth of Grätzer/Grodziskie being a sour beer once and for all. Though I fear I may already be too late. Once a piece of shit information gets out there, it's repeated endlessly until the end of time. Or at least that's what it feels like. I suspect I'm going to be arguing about this one for decades.
I was slightly disappointed, having read that 7.9º Plato was the standard gravity for Grätzer/Grodziskie, to discover that two of the samples were lower than that. The Hochschulbrauereiversion was bang on 7.9º Plato, but Vereinigte Grätzer Bierbrauerei's was only 7.36º Plato and Monopolbräu's only 7.03º Plato. Due to the reasonably high level of attenuation, all come out close to 3% ABV.
I'd love to know how that colour measurement relates to any scale I can understand. As it is, the colour numbers only tell me one thing: that the Hochschulbrauerei version was darker than the other two.

I told you I was going to be brief today. Not worry, I've got a real monster of a post coming up. I'd wondered what the maximum size of a post might be. I think I've found out.
