I’m only certain about the last two entries in the table. They’re definitely Hallertau. A could stand for Auscha, a hop-growing region in Czechoslovakia. In which case they would be something akin to Saaz. By this point, of course, Czechoslovakia was also occupied by the Hermans. As for Bacha, I’ve absolutely no clue.
Before the war, Heineken seemed to use mostly German hops which meant little changed after the outbreak of war. It would have been a different matter had they been accustomed to employing English or American hops.
