Over the whole course of the war, Adnams XX lost a mere two gravity points, falling from 1029º to 1027º. There was a good reason why the gravity didn’t fall below 1027º: the way the tax system worked it made no economic sense. The tax equivalent to a beer of 1027º was the minimum charged, whatever the strength of the beer.
Just as with the gravity, there was very little change in the hopping rate of XX during the war. Despite brewers being ordered by the government early in the war to reduce it. Though Adnams’ hopping rate was a good bit lower than at either Whitbread or Lees. It started around 5 lbs per quarter (336 lbs) of malt. While Whitbread’s rate went from over 8 lbs per quarter to around 5.5 lbs. While Lees went from around 7 lbs per quarter to 5.5 lbs.
