More WW II-related IPA fun. When will it end?
It will come as no surprise that the strength of IPA brewed in the capital declined considerably during the war. As with other styles, this mostly occurred during the first three years, after which it remained stable. At least until the end of hostilities, after which there was a further drop.
Barclay Perkins IPA seems to have dropped down a class by 1942, being just about the same strength as Whitbread’s version. XLK (Bottling) appears to have been dropped to give up its slot to IPA.
Averaging around 20, the colour is the same as pre-war. Whitbread’s version continued to be very highly attenuated, with every example bar one over 80%.
