With war still raging in Europe, taxes were high in 1812. Which explains the rather modest gravity of this Stout.
In the last few years before the appearance of black malt, London brewers had replaced much of the brown malt with pale malt. But it still made up at least a third of the grist. The result is a colour which today loos awfully pale for a Stout.
Happily, this Truman brewing book didn’t encode the mashing temperatures. Revealing a four-mash scheme. Kicking off with two at around the same temperature, then a hotter one and finishing with another like the first two. Don’t ask me why they mashed this way.

The fermentation was short and hot, lasting just four days and peaking at 83º F.
One type of hops: English from the 1811 harvest.
