London Stout 1910 -1920

To call WW I a monumental shock to UK brewing is no overstatement. Though, while it may have put the boot into Porter, Stout managed to struggle through the war, albeit at a greatly reduced strength.

Not that Stout was brewed without interruption throughout the war. Some brewers discontinued their Stout and simply sold their Porter as Stout. Once the most draconian limits on gravity were loosened, Stouts were on the menu again. Though obviously at a much lower strength than in 1914.

After the war, Porter in London went into terminal decline, limping through until WW II. While Stout continued to be brewed in large quantities. Though even it was becoming rarer on draught.

Over on the South bank of the river, Courage managed to brew their Stout right through the war. In contrast to Fullers, who dropped their Stout, but continued with their Porter. Courage did the exact opposite, discontinuing their Porter in early 1918 and not bringing it back until 1920.

Though if you look at Courage Stout in 1918, with its puny gravity of 1036.5º, it looks more like a Porter.

I’m surprised that Courage were able to brew a beer over 1060º as late as January 1918. Lucky devils who got to drink it. After surging over 1050º in late 1919, the gravity settled down in the mid-1040ºs right up until WW II. While many brewers opted to brew their Stout as an 8d per pint beer, Courage plumped for a 7d beer.

The hopping rate per quarter (336 lbs) of malt, other than a brief rise in 1915, was in decline throughout the war. Between 1914 1nd 1918 the fall was almost 25%.

I've seen it said that porter became completely extinct in British brewing for a few years in the 60s(?) or 70s (not sure when exactly). But would it be more accurate to say surviving porters were simply rebranded and subsumed into the, now weaker, stout lineups post-war? The beer was porter but the label said stout kind of thing?

Cairnes as early as 1912 was walling its weakest porter single stout.
