Obviously, AK was part of a parti-gyle which included XK and PA, its two stronger siblings. This particular parti-gyle consisted of just 3.25 barrels of AK, along with 136 barrels of XK and 166 barrels of PA. Clearly AK wasn’t a major brand for fullers.
Back before WW I it had been, with Fullers turning out 300-odd barrels at a time. But the war wasn’t kind, reducing AK’s OG to the low 1030ºs. Which may account for its poor sales. Bitters that weak weren’t very common in London. The batches are so small, there could only have been a handful of pubs taking the beer.
The recipe, inevitably, is identical to XK and PA. Despite its low gravity, AK still comes out to a very reasonable 35 (calculated) IBUs.
