There wasn't just one sort of IPA between the wars, bot two. One, which I'm imaginatively calling "Strong", and the other, which I'm equally imaginatively dubbing "Weak".It's purely arbitrary as the examples below scan a gravity range from just over 1030º to just a hair short of 1060º. And just about everything inbetween. I just opted to split them at 1045º. Which is about halfway.
Fascinating to see an English and a Scottish IPA in sale in Belgium. Not a style particularly associated with the cross-channel trade.
Most are highly-attenuated, but there are a few exceptions. The two examples from Fussell stand out in particular, with their much lower degree of attenuation..11 of the 16 beers were over 80%.
Alcohol content is all over the shop: low 2.8%, high 7.3%. What would a drinker expect when ordering an IPA? No doubt it depended on where you lived. And what the local brewers decided IPA was. Imagine what might happen if an IPA fan visited a town where his favourite was double the strength.
