Another beer making a reappearance was Oatmeal Stout. No surprise, as it was a popular kind of beer, at the time

Most brewers just threw a handful of oats into their standard Stout and labelled some of it as Oatmeal Stout. Barclay Perkins took a different approach. They brewed it separately, in a tiny batch (just over 24 barrels). So, did they use more oats? Of course, they didn’t. A mere 30 pounds.

There are a lot of ingredients. A bit of flaked maize here, a little crystal malt there. Roast barley for colour this time. The sugar is described as “Martineau BS”. I would have assumed that meant something like No. 4 invert. But that would make the beer way too dark. No. 3 gets it around the right colour.

Just four steps to the mash. Perhaps because of the small volume they didn’t bother with a second sparge.

Only two hop types, both Mid-Kent, one from the 1923 harvest, the other from 1924. Both stored cold.

More Martineau BS was added as primings, raising effective the OG by 2º. I’ve added more No. 3 invert to account for this.
