By modern UK standards, Porter was still quite a strong beer, clocking in between 5% and 6% ABV. That would no longer be true after WW I. The low gravity of versions produced in the 1920s might well have speeded the style’s demise.
As you can see in the table, the gravities of the examples from different breweries were of a very similar gravity, averaging out to exactly 1057º. Wildly differing degrees of attenuation, however, left a wide spread in the alcohol content, from under 4% ABV to just shy of 6% ABV.
The hopping rate was mostly 7 and a bit pounds per quarter (336 lbs) of malt. That’s slightly higher than for London Mild Ales, but not by a huge amount. There were a couple of outliers with higher hopping rates. In particular a couple of the earlier Truman examples.
