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:

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