Today's table comes from the thinnest book I've ever seen. It had no pages at all, consisting of just a hard cover with loads of numbers written on the inside. Those numbers are an overview of the draught beer sold in London between 1929 and 1951. By type.
It's not the beer brewed at Horsleydown, but the beer sold in Courage pubs. How do I know that? Because it include APA (Alton Pale Ale) which was brewed, who would have guessed, at Alton. How can I be so sure? I've looked in the Horsleydown brewing records for 1929, 1930 1932 and 1937 and there's no Pale Ale.
A word of explanation first. About the beers. Porter is pretty obvious. BS = Brown Stout. C, CC and MC are Milds. Don't ask me why they're called that. XXX looks like a Burton and KKK a Strong Ale. These were their gravities:
OK. Explanation done. Here's the table:
By the late 1930's, Courage's draught Porter was clearly on its last legs. Even without WW II, it looks as if it would have disappeared in the early 1940's.
What struck me more when I looked more closely was the even more rapid decline of draught Stout. In 1929, with over 25,00 barrels sold, it was a pretty mainstream product. By 1940, it was on the edge of destruction. Surprisingly, it made a brief reappearance in 1945 and 1946 before disappearing forever.
