Rather surprisingly, this set averages out stronger, both in terms of OG and ABV. Though that's a little deceptive, as the older set didn't include any Burton-brewed beer. Bass Pale Ale still had a gravity of 1065º. Looking at it from that point of view, Burton IPA had lost about 10º on account of WW I.
The beers sold in Belgium look much like the domestic ones, at around 1055º. Attenuation remains mostly very high, averaging over 80%. Leaving them almost 7% ABV
1055º isn't a random choice. The top band of the last set of WW I price controls started at that gravity. Anything over 1055º could only be sold for the same maximum price. It made no economic sense to brew anything much over that gravity. It had a lasting effect on beer strengths all the way through the interwar period. Particularly amongst draught beers.
Lost interest yet? I wouldn't blame you. I'm nodding off as I write.
Loads more information about more recent IPAs. Plenty of the lovely weedy ones. Mostly lovely weedy ones, if I'm honest.
