Let's Brew Wednesday - 1941 Barclay Perkins KK

Just for a bit of variation, today's recipe isn't a Stout. And not from the book I'm working on. Well, not working on currently, as it's just about finished. Maybe I'll get around to publishing it soon.

Not much seems to have changed since 1940. At least not in terms of strength. That could be because this was brewed fairly early in the year, in April. While the 1940 recipe above is from September.

The grist has seen one big change: the dropping of adjuncts. Leaving it malt and sugar only. Barclay Perkins hadn’t brewed like that since the 1880s. The percentage of mild malt has increased slightly at the expense of pale malt. And this time, it really was all mild malt in the original. The SA malt has been dropped.

There’s also been a change in process, with the boil time of the first wort being reduced by 15 minutes. Presumably to save fuel.

The hopping rate has remained around the same, though the quantity of dry hops was reduced from 3 oz. to 2 oz. per barrel. The hops themselves were Kent Goldings and Kent Fuggles both from the 1938 harvest and kept in a cold store. While the dry hops were Goldings from 1939.
