If you’re wondering about the cryptic name for this beer, it’s quite simple, really. P stands for Pale Ale and 1/4 is the retail price per pint. It’s very Scottish to name beers by their price. I wonder why?

The system isn’t great in times of inflation. By 1965 the name was P 1/8, the price having gone up by 4d per pint. And it didn’t stop there.

Usher’s records for this period are wonderfully detailed. Before WW II they were in the typical Scottish format, with multiple brews spread across two pages. But these are two pages per brew, one with the brewing details, the other logging the progress of the fermentation.

As the malt extract was added to the mash tun, I assume that its purpose is enzymatic.

Typically, the grist is just pale malt, flaked maize and sugar. The last, in this case, being invert and DAS. Which I’ve interpreted as No. 1 and No. 3 invert, respectively.

The hops were English, more I don’t know.
