Let's Brew Wednesday - 1942 Barclay Perkins X

Half way through the war, things weren’t looking great for X. The gravity is down 4.5º on the previous year.

Lots has also been happening with the recipe. It’s a great example of the effect of wartime shortages on beer grists. There’s a bit of everything: pale malt, lager malt, light amber malt, torrefied barley, flaked barley, crystal malt and sugar.

Obviously, a recipe as weird and complicated as this wasn’t deliberately developed. They were using whatever fermentable material they could get their hands on. The overall result, however, leaves the adjunct percentage around the same as in 1940. There’s considerably more sugar than in 1941 – about double the amount.

The primings – which added about 2º to the effective OG – would also have darkened the colour. As sold, X was 20 – 25 SRM. The paler version, which was around the colour as brewed, i.e. as indicated in the recipe below, had been discontinued the previous year.

Three types of Mid-Kent hops from the 1940 and 1941 seasons were used, the former having been kept in a cold store.
