Despite being pretty much exactly the same strength, pre-war there was a big difference in the hopping of Heineken Pils and Whitbread PA. The rate of the latter being around 50% higher. But while the hopping was reduced at Whitbread, it was increased at Heineken.With the result that in the middle of the war the gap between the two narrowed to almost nothing.
Weirdest is the situation in early 1943, when Heineken suddenly started hopping far more heavily. Supply of hops doesn't seem to have been a problem for the Dutch during the war. With supplies from Germany being maintained. Unlike barley, there always seem to have been plenty of hops knocking around on the Continent.
Once the war was over, Heineken's hopping was a little bit higher than it had been in 1939. While Whitbread's was a little lower.
