Porter after WW I

In the early 1920s, London Porter went into a dramatic decline. Its last bastion in the UK started to crumble. Sales of Porter plummeted, possibly in response to the dramatic fall in strength. In the immediate aftermath of WW I, most had gravities in the low 1040ºs – about the same as Best Mild – a 7d per pint beer. Soon it had been dropped down a couple of classes, to a 5d beer. The same strength as the weakest Milds, successors to the dreaded wartime “Government Ale”.

Looking at the numbers from Whitbread, it looks as if many Porter drinkers may have shifted their allegiance to draught Stout. A beer which was much like the Porter from before the war. I can’t blame them. Given adequate financial resources, I’d have done exactly the same.

As London brewers parti-gyled their Porter and Stout, they were beers of very similar character. If you wanted a beer like the Porter of 1914, Stout was your obvious choice in the 1920s.

Outside London and Ireland, Porter was stone dead after WW I. Even in the capital, it wasn’t doing that well. Though most brewers still produced one. Though, had they not been parti-gyled with Stout, I doubt many brewers would have bothered brewing Porter even in London.
