When WW II erupted, Barclay Perkins were producing four Pale Ales, in descending order of strength: PA, XLK (Trade), IPA and XLK (bottling). By 1944 just IPA and a single version of XLK remained.
The bottling XLK had always been lower in gravity than XLK (trade), which was the draught version. The single XLK brewed in 1944 was the same OG as pre-war bottling XLK. Effectively they had eliminated the draught version and used the bottling version for both. 1944 XLK, in terms of strength, looks like a typical post-war Ordinary Bitter.
The grist of XLK had become considerably more complex during the war. At the start it was just pale malt, PA malt and flaked maize. Plus some sugar, of course. The 1944 version was a combination of PA malt, SA malt (for which I’ve substituted mild malt), crystal malt, lager malt and flaked barley.
Excuse me if I’m repeating myself, but crystal malt wasn’t common in Bitter before WW II. Barclay Perkins only began to employ it in 1941. Perhaps to compensate for the fall in gravity. Lager malt appears in several of their beers around this point. I assume they just had some extra lying around that they wanted to use up.
The hops were Kent Fuggles from the 1943 harvest, Mid-Kent Fuggles from 1943 and 1944, Worcester Fuggles from 1942, plus East Kent Goldings dry hops from 1944.
