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. (http://barclayperkins.blogspot.com/2022/01/lets-brew-1890-truman-imperial-stout.html)
