On the pursuit of Boddingtons:
I gave up looking for "alternatives" to the 1971 recipe (that Ron Pattinson dug up and was linked into this thread by
@Northern_Brewer).
@Hanglow suggested Bass/Worthington brews were also very highly attenuated, but the "very highly attenuated" (which I take to mean FG 1.003-1.004) ones were only dotted about the records Ron P. publishes. Perhaps the Boddington's "very highly attenuated" bitters were the same (i.e. occasional "blips")? But following this line of thought I came across this:
Boddington beers after WW II
... the important bit being "A big increase in the rate of attenuation means that Boddington Bitter remained over 4% ABV, despite the reduction in gravity", this following the WWII bombing in December 1940 that put the brewery out of action for a few months and presumably is the moment the yeast from Tadcaster was brought in? So this implies "very high attenuation" was more than just a blip in the case of Boddington's?
This was what interested me! A beer of FG 1.007-1.008 wouldn't interest me; I know I wont like it. But a beer of FG 1.003-1.004 transcends my definition of "beer" and is in (dry) "Saison" territory. Now that'll be worth trying!
Pre-war Boddington's (e.g.
Shut up about Barclay Perkins: Let's Brew Wednesday - 1939 Boddington IP ) has nothing exceptional to persuade me to try it.
I wouldn't be brewing such a beer this side of next May, so I'm stopping my search for alternatives just now: The Boddington's 1971 recipe looks fairly standard for that time* (apart from the FG!) so I don't really need an "alternative".
* i.e. Small additions of flaked maize, "enzymic" malt, sugar; in place of 100% pale malt. Goldings and Fuggles hops still dominating with inclusion of American hops (Clusters) getting rarer.
