It wasn’t only wars which negatively affected UK beer strength. A steady creep of tax increases also had an impact. Not the massive ones seen in WW I and WW II, but still enough to exert a downward pressure on gravities.
This second set of London X Ales has an average gravity of almost 5º lower than the ones from the last two decades of the 19th century. With a to be expected lowering of the alcohol content by 0.5% ABV. Especially as the average rate of attenuation remained exactly the same at just a shade over 75%.
The largest change, however, is in the hopping rate. Looking at the one which is gravity-neutral – per quarter (336 lbs) of malt – it’s fallen by 35%. A fall large enough to have changed the character of the beers. Especially as there wasn’t a switch to higher alpha acid hops. Because of the fall in gravity, the rate per barrel has fallen even more: 45%.
