This particular KK is from Crowley of Alton in Hampshire. Hand on, I'll just consult Barber to see what the hell happened to them.
Founded 1763, bought by Watney 1947, closed 1970. So I only missed it by a couple of years. Not that I was likely to have been down that way. Still never have, for that matter.
The table covers the years of WW I. Whay is that? Because those are the years I have for Crowley. I didn't harvest the records I have myself. They were passed on to me by Edd Mather (thanks, Edd). It is a good illustration of what happened to UK beer in WW I. Bit of a drop in gravity in the first two years, then all sorts of craziness in the last two.
It looks to me that they were deliberately boosting the attenuation in the later war years to keep AK at least vaguely intoxicating. Though the attenuation was never much under 75%.
The hopping rate was fairly constantly around 6 lbs per quarter of malt (looking at the hops per quarter rate effectivley takes the strength of the beer out of the equation). Though after 1915 the hops became progressivley older. In 1919 they were still using Oregon hops from the 1912 harvest.
Grists next. Very illustrative of the war they are, too.

90% attenuation seems pretty unusual for British yeast, unless they have a magic touch of some kind.
7 year old hops? Not sure if any AA would've survived to that point.But I guarantee they would've added plenty of Limburger notes...
That's an heroic effort to keep some alcoholly goodness in their low-gravity beers in 1918. Bravo!
