Let's Brew - 1890 Truman Double Stout

At times, Truman did some weird stuff with their parti-gyling. The way they brewed Stouts in the 1890s being a good example.

Because, as well as blending pre-fermentation, there was a second blending post-fermentation. In the first, 3 gyles of 1113º, 1089.2º and 1038.2º were blended to create these three worts:

Beer barrels OG
Imperial Stout 189 1097.0
Double Stout 189 1083.1
Single Stout 296 1070.4

After fermentation, 69 barrels of Imperial stout were mixed into the other two Stouts. With this result:

Beer barrels OG
Imperial Stout 120 1097.0
Double Stout 218 1082.0
Single Stout 345 1076.2

Not sure why you’d do this rather than get the quantities and OGs you want in the pre-fermentation blending.

I know from a Truman square book that Double Stout at least sometimes was vatted. I’d guess for at least 12 months.

For recipe details, see the Imperial Stout recipe I published a while back.

Hi Ron,

sorry if I'm missing something, but why does this recipe give an OG of 1076 if that was the strength of their single stout? Shouldn't it be 1082 for the double stout?

Your title says "Double Stout", but the recipe is the "Single Stout".

Ah, I included the wrong recipe. Now fixed.

Completely unrelated: will this be the revival of cask and bottle conditioned beer?
