Real Kulmbacher

As promised, a look at a real Kulmbacher. Not just a concoction of pale beer and colouring. Or maybe it isn’t quite that simple.


“A sample of Kulmbacher beer delivered to an Institution was, because of its pale colour, which significantly differed from the beer as previously served, suspected of being watered. The analysis showed:

Specific gravity 1.0262
Alcohol 4.76%
Extract 7.35%
Minerals 0.27%
Nitrogen substance 0.62%
Lactic acid 0.27%
Maltose 2.19%
OG 16.36%
Degree of fermentation 55.07%

It was, therefore, a normally composed, content rich Kulmbacher beer whose pale colour was merely due to the fact that the Kulmbacher breweries no longer colour their beer with sugar colouring since the famous verdict of the  Criminal Court in Bayreuth.”

Now isn’t that interesting? Kulmbacher, as we saw last time, was dark. Very dark. Now we know why: they were darkening it with caramel. I’m just trying to work out how that could ever have been OK in Bavaria, where I thought they were pretty strict about the Reinheitsgebot. Evidently not that strict.

I’m just guessing here, but that Bayreuth court decision looks like it was responsible for the rise of Sinamar, the beer-derived, Reinheitsgebot-compliant caramel substitute.

Looking at the specs, that beer would count as a Bock today, with an OG over 16º Balling and around 6% ABV. Though it was pretty typical for a Kulmbacher of the day. As this table demonstrates (our lad is the last one in the table):

As you can see, the suspicious sample is very close to the average for Kulmbacher Export.

More Kulmbacher or Porter next? It’s so hard to decide.
