Just when I thought Maclay’s records were as exciting a wet February weekend in Skegness, they throw in something completely different. Not an Oatmeal Stout, but an Oat Malt Stout.

Maclay were the first to brew an Oat Stout, way back in the 1890s. They tried to patent Oat Malt Stout, but other brewers simply used flaked oats and called their beers Oatmeal Stout. It’s weird that the two new types of Stout that appeared 1890 – 1910 both came from small, regional breweries. Oat Stout by Maclay, Milk Stout by Mackeson.

While London brewers threw in a token amount of flaked oats into their Oatmeal Stout, Maclay’s version always contained a considerable proportion of oat malt. In this example, it makes up a full third of the grist.
