The question which immediately springs to my min is: “If this is the Keeping Imperial Stout, is the other one a Runner?”
Looking at the numbers, the answer could well be “yes”. The hopping rate is much higher: 10.1lbs per quarter (336 lbs) of malt compared to 5.6 lbs. That looks like the difference between a Runner and a Keeper. The OG here is a bit higher, too.
A classic London grist of pale, brown and black malt was employed. (Some of the pale being made from Chilean barley.) Along with some sugar of a not clearly specified type. “Fowler P.”. Fowler was a manufacturer of invert so No. 3 isn’t such a crazy guess. Still loads of other things it could have been.
The FG is a total guess. Something this strong would usually have been aged for at least 2 years. Depending on how active the Brettanomyces was, that could have left the FG surprisingly low.
Most of the hops were Kent from the 1908 and 1909 crops, the former cold stored, as well as some Oregon from 1908.
