I'm so glad that I have some Heineken brewing records from WW II. If only to demonstrate that things weren't all that bad in the UK
The other vaguely-intoxicating Heineken beer of this period is Beiersch. Though, like Pils, it’s had 10º lopped off its OG.

Similar changes to the grist to in Donker Lagerbier have been made. Namely a doubling of the quantity of caramel malt and a big increase in the amount of carafa. And just about 20% of the base malt has been replaced by sugar. Despite more dark malt being employed the colour has become quite a bit paler.

Quite a sizeable reduction in the hopping rate has, despite the fall in gravity reduced the (calculated) bitterness level from 15 IBU to 12 IBU. The hops were a single type of Hallertau from the 1940 crop.
