London vs provincial beer in the 1930's: Bitter

In the second part of this series we'll be taking a look at Bitter brewed inside and outside London.

Despite several London brewers (Truman and Mann, among other) owning breweries in Burton, there was a considerable amount of Pale Ale brewed in London. It made up a big chunk of the beer brewed at Whitbread's Chiswell Street brewery. While Courage brewed none in London, bringing it in from a plant they owned in Alton, Hampshire.

First it's the turn of London Bitters. I'd say that there were two types 8d and 7d Pale Ales. Nos. 12 and 14 are the former, the others the latter. Which leaves a rather muddied picture, especially as the number of samples is small.

Note the very low figure for residual solids. These beers are all pretty well attenuated.

Now for country Bitters, which are even more diverse:

That's quite a spread of ABV's, from 3.05% to 5.92%. Anything under 4% ABV was pretty weak for a Bitter in the early 1930's.

Once again, the London beers are stronger, but in this case it's the country beers which have more residual sugars. The two balance out, leaving the calorific value of London and Country Pale Ales nearly identical.

Now a direct comparison of the averages:

Calories per pint.
Total Solids per cent. Absolute Alcohol (by weight) per cent. Ratio of Total Solids to Alcohol (T.S.=1). ABV Solid Matter. Alcohol. Total.
London 3.78 3.92 1:1.03 4.98 88 156 245
Country 4.29 3.62 1:0.84 4.60 100 142 242
% difference 11.89% -8.29% -0.31% -8.29% 12.00% -9.86% -1.24%

I'm not really seeing a pattern yet. Other than London beers containing more alcohol.

I'm not even seeing that! The highest ABVs in the sample are all from country beers. But the range also goes down a lot lower in the country sample - so you could say country beers contain less alcohol.

So when people get misty-eyed about the great tradition of sub-4% bitters, they're really feeling nostalgic for.. what? The 1950s?

"Anything under 4% ABV was pretty weak for a Bitter in the early 1930's."

Was the sub 4% been filled by the AK's?

Bailey - mild, I guess. There's a great tradition of sub-4% wallop, just not bitter.
