There’s a big difference in the hopping rate of London Milds and those brewed elsewhere. For example, Tetley’s Milds contained 3.5-4 lbs of hops per quarter (336 lbs) of malt, Fullers 7.5 lbs. In fact Fullers Milds were more heavily hopped than most provincial Pale Ales. This is reflected in the 37 (calculated) IBUs.
I’m not sure what the final colour of XX was. Based on the ingredients listed in the brewing record, it doesn’t come out that dark. However, I know that some other London brewers darkened their Milds at racking time. Unfortunately, the earliest Whitbread Gravity Book analysis that I have is from 1951. That lists X Ale as around 22 SRM.

I've got a question not directly related to today's recipe but it did come while listening to an interview with Fuller's John Keeling... he was describing the gravity of one of their beers and and was saying the starting gravity was "58 point 6" and the finishing gravity was something like "8 point 8".
That's obviously not Plato because that would would be a SG of 1.283! So is he saying that the SG is 1.0586? Also, I assume that 58.6 could be rounded up to 1.059?
Sorry if I'm asking something elementary and dumb but I've never heard gravity stated that way.
Thanks
Kevin,
he means 1058.6. So he must have been talking about the export version of ESB, which is the only one of their beers which has that OG.
UK brewers never use Plato. Fullers only went over to using SG fairly recently. Until at least 1968 they measured gravity in brewer's pounds.
@Kevin
Bear in mind that Fuller's typical brewlengths are multiples of 260hl (a tad under 160bbl) and that they are taxed in proportion to alcohol. The rounding error on 260hl between 1.0586 and 1.059 becomes a significant amount of extra tax, it's worth being accurate...
qq,
but tax isn't on the OG any more, but the ABV at the brewery gate.
Incidentally, many Barclay Perkins records give the "declared gravity" as well as the actual gravity. It's usually rounded down by 1º.
