For the first months of the German occupation, Heineken continued much as before the war. The changes kicked off a week into November, when rice was dropped from the grist. The gravity had been reduced a touch towards the end of October, dropping from 11.8º Plato to 11.5º Plato. Not such a big deal.
The dramatic change happened on 17th November, when the gravity went back up to 11.8º Plato, but in was watered down with boiling water in the cooler to 10º Plato. It was the first in a series of dramatic changes which occurred in late 1940 and 1941. At least it was still just about 4% ABV.
I’ve not much idea what the hops were, other than mostly German. One is described as “A”, which could stand for Auscha, a Czech hop region.
