Shut up about Barclay Perkins - Nürnberg Winterbier and Sommerbier 1886-1887
Visit the Shut up about Barclay Perkins site
I'm slowly ploughing my way through the 1903 edition of "Chemie der menschlichen Nahrungs- und Genussmittel". It has over 1,000 analyses of beers, mostly German but with examples from most major brewing countries.
I've already harvested the analyses from a couple of earlier editions, which means there are only 100 or so I need to collect. To add to the 20-odd thousand in my main gravity spreadsheet. It's getting to be quite a collection. Which is sort of the idea.
To quickly recap, in the 19th century Lager was split into two main types, Winterbier and Sommerbier. Before refrigeration, both were brewed in the winter, but the Sommerbier was stronger and lagered for longer because it needed to last through the summer. Sommerbier was also called Lagerbier and Winterbier called Schenkbier.
This is a particularly useful set of analyses because it has the Winterbier and Sommerbier from the same brewery for the same brewing season. Which means we can make meaningful comparisons between Winterber and Sommerbier.
A couple of general observations to begin. I'm shocked at the high lactic acid content of every sample. I'd have expected it to be no higher than 0.1%. Over 0.2% I would have expected to give the beer a detectable tartness. The gravity of most beers is surprisingly high. The strongest Sommerbiers look more like Bocks, with gravities over 1060º and ABVs over 6%. The modern equivalents of these beers - Helles or Dunkles Lagerbier have much lower gravities, usually around 12º Plato or 1048. On its website, Tucher amusingly claims that the recipe for Original Urbräu has been the same for 150 years. Clearly that's bollocks
There are a couple of examples where clearly the same beer has been analysed as both a Sommerbier and a Winterbier: Tucher, Lederer and Lechner.

As you'd expect, the Sommerbiers have a higher average gravity: 1058 compared to 1053.6. So a difference of 4.4 points. But there was considerable variation across different breweries. Ranging from a negative 0.3 points at Mailänder to a massive 11.7 points at Dürst junior. Interestingly the average FGs are almost identical at 1016-ish. The inevitable consequence of which is that the degree of attenuation of Winterbiers is lower. Modern Lagerbiers are very different, averaging well over 80% apparent attenuation.

The Sommerbiers range from 1048.8 to 1064.7 and the Winterbiers from 1047.6 to 1059.6. Which means that the weaker Sommerbiers have a lower OG than many Winterbiers. It's a lot more variation than you would see in British beers of the same type from the same region. Though 14 of the 28 samples of Sommerbier had a gravity within two points of the average. For Winterbier, that was 13 of 23.
Unfortunately there's nothing about hopping rates. So I can't confirm that Sommerbier was more heavily hopped than Winterbier.
I'm sure I'll be worrying you with plenty more from "Chemie der menschlichen Nahrungs- und Genussmittel". It's so full of information.
