There are some intriguing differences between the Stock and Running versions of No. 1.
The grists are similar, but not identical. There’s around twice as much crystal in R1. And it also contains some flaked maize, which S1 doesn’t. But it’s the sugar that confuses me. Why is there No. 1 invert rather than No. 3? It results in R1 having a much paler colour. Which I find odd.
You’d expect R1 to be less heavily hopped, and it is. It contains about exactly half as many hops per barrel. And, sure enough, the calculated IBUs are about exactly half those of S1. I know nothing about the hops themselves, other than that they were all English.

Do you have a sense what the proportions of each in the blend would be?
ReplyDeleteAlso is there any sense how much carbonation there would be for priming purposes? It would be an interesting project some day to make this.
I came across a fascinating 2013 article about Truman, in zythophile.
ReplyDeleteThe article is well researched but the comments section is great, with a guy who actually worked at Truman in the early 1970s

ReplyDeleteaccording to Derek Prentice, the blending was done by taste. The main idea being to temper the acidity of the aged beer.
