Barclay Perkins X Ale grists 1935 - 1936

As promised, here are the Barclay Perkins grists. Well, some of them.

I’ve decided to split them up to make the tables a bit more manageable, I’m kicking off with X Ale. Basically standing in for all of their Milds. Because X Ale was in all of the Mild parti-gyles and sometimes single-gyled.

When I started harvesting these records I was struck by how much the grists changed over a short period of time. Without there being external factor, like a war, forcing changes. I’m not really sure what to make of it. For example, why does one version randomly contain some lager malt?

Let’s take a look at the grains first. There are several ever-presents: pale, amber, crystal and mild malt, plus flaked maize. But only the pale and crystal malt percentages are reasonably constant at around 20% and 5%, respectively. While amber malt and flaked maize are all over the place, with a variation of over 100%.

There’s a similar story with the sugar:

The only sugar used in every grist was caramel, which was used for colour. I would have expected No. 3 invert to be in all the grists. That’s the usual Mild sugar. It seems odd to find No. 2 invert, which was usually used in cheaper Pale Ales.

All of the hops were English and from Kent. Mostly Fuggles, but with some Goldings, too. Nothing unusual there, though a lot of brewers would have been using North American hops in the 1930’s.

Hi Ron,
I'd look at the extract poundage from the brews without the lager malt, the the one with , if they're roughly the same I'd say the lager malt was for extract , in a similar way to the use of Ouchak, Smyrna etc and n the records I've seen from northern and Burton Breweries.
Cheers,
Edd
