It's the grists we'll be looking at. As XXX and KKK were parti-gyled together, there's not much point looking at the grists separately. Except for one item: primings.
The logs give full details of the primings used, broken out for each beer in the parti-gyle. Logical enough, since as the primings were added after primary fermentation, when the beers were separate. Courage primed all their beers except one: KKK. Occasionally they primed it a little, but in general not. Was that because they were leaving it to age a little? Primings are generally used to bring a beer into condition quickly.
There's an awful lot of crystal malt - almost 18% of the grist in one case - in some examples. Coupled with relatively modest hopping, it must have resulted in quite sweet finished beers. Pale is the only other malt used, apart from a tiny amount of black malt in a couple of early examples.
The sugar content, on the other hand, is quite low, never topping 14%. It's in the form of No. 3 invert, which is exactly what you would expect in dark beers like these. The vast majority of the colour would have come from this and the caramel.
Finding some flaked maize is no surprise. Most brewers used it from what I've seen in brewing records. Whitbread is the only notable exception, using only malt and sugar in their grists.
The hops used are interesting. A mix of West Coast US hops and English hops, in every case. Again, pretty typical practice for the time. The fascinating bit is the occasional use of Saaz, a hop which seems to have been held in quite high regard by British brewers.
There. We're finally done. Have to think of something else to bore you with now.
