Let's Brew Wednesday - 1944 Barclay Perkins KK (trade)

The draught Burton of Barclay Perkins had seen some changes since the outbreak of war. Most obviously, to its strength.

The gravity was down about 20% on its pre-war level, more the fall in average OG which was about 15%.  In general, strong beers suffered heavily from gravity cuts. That’s if they were still brewed at all. Little over 5% ABV was brewed in the later war years.

The effective OG would have been a point or two higher on account of the primings added at racking time: 2 quarts per barrel of a sugar solution with a gravity of around 1150º.

The grist isn’t hugely different from pre-war. The base malt has been simplified, with the mild malt and pale malt being dropped in favour of 100% SA malt. For which I’ve substituted mild malt. Confusing, I know. And flaked barley replaces flaked rice. Bizarrely, there’s a small amount of lager malt. I’m guessing because they had some spare lying around.

The hops were Kent Fuggles from the 1941 and 1943 harvests and Mid-Kent Fuggles from 1943. The dry hops were East Kent Goldings from 1944.
