Let's Brew - 1941 Truman XX

More results from my latest archive visit.

I'm finally back to writing my new book. Travelling to London, photographing at the archive then extracting the information took about two weeks out of my schedule. Research is a very labour-intensive activity.

Next up in strength amongst the Mild Ales remains XX. Though it hasn’t been as lucky as X, losing 2º since 1940.

Though that has partially been offset by an even higher degree of attenuation, leaving the ABV a respectable 3.77%. So at least it retained a reasonable amount of poke.

I’m pretty sure that this is really the pale version of XX. I’m not totally sure why they maintained the differentiation in the Brewhouse between the pale and dark versions of X and XX. Mostly they look exactly the same. The difference I assume, coming at racking time with different primings or simply an addition of caramel.

There’s been a massive reduction in the hopping rate, from 7 lbs per quarter (336 lbs) to 3.5 lbs. Unsurprisingly, the result has been a halving of the (calculated) IBUs.

For further recipe notes, see the X above, with which this was parti-gyled.
