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.
