In 1941, they brewed quite a lot of beer still - over 300,000 hl.I assume that they brewed a similar amount in Amsterdam. At an average OG of 8.1º Plato, isn't too bad. Bit look at the trend: downwards, finishing at under 6º Plato at the end of the year. To put that onto context, average UK OG in 1941 was 1038.5º - that's about 9.6º Plato. In just a few months, Heineken's beer had gone from being about as strong as that in the UK to being watery piss.
It's more beer than they manged to brew more than the previous year's 306,919 hl.* Not that bad a result, I suppose, 324,849 hl. in 1941. The trend did look to be downwards, with December output the lowest for the whole year.
