Other Dutch Lagers in 1941

Yet more watery Dutch Lagers from WW II.  Hopefully, at least a couple of you find this stuff as interesting as I do.

Oddly, Licht Lagerbier was hardly any weaker than Pils. Though, if you look closely, you’ll see that the samples are from a few months earlier and are still around the pre-war level of 8-9º Plato. Had the samples been taken a little later, the gravities would have been around 6º Plato, just like the Heineken version a couple of pages back.

On average, the Licht Lagerbiers are a bit darker than the Pilseners, though not really by a significant amount. The rate of attenuation is almost identical at a little over 74%.

A couple of examples – Amstel and Bavaria – are around the pre-war level of 3.5% ABV. The weakest are only about 2% ABV.

In comparison, the dark Cooking Lagers are 0.5º weaker than their pale siblings. The mostly lower rate of attenuation drops their average ABV below 3%. Only two examples are over 3% ABV.

There’s a massive variation in colour, from 6.8 to 22 on the Brand scale. Which is equivalent to 42 to 95 EBC. So between dark amber and dark brown.

It would be interesting to see if any of these data trends correlate to major setbacks in German power, or if the trend lines are just a consistent downward slope.

Looking back at posts I can see by 1943 gravities had collapsed, but I don't know if there was an obvious time that they went into freefall that might connect to something like stepped up Allied bombing of railroad networks. Or on the other hand maybe there is no sudden fall, and declining malt usage represents a gradual constriction of raw materials.
