In the first decade of the 20th century, Oatmeal Stout became a big thing. The original Oat Stout came from Maclays of Alloa, who tried to patent their invention. Most brewers dodged this by simply using oat malt instead of malted oats.

It’s a pretty complex grist. Even more complex than it appears from the recipe. As around a third of the base malt was SA malt. Obviously, there are also oats. I think in the form of flakes. But not a huge amount of them. Unlike the roasted malts, which make up more than a third of the total.

The mashing was still going the same way: mash, underlet, mash, sparge, sparge. Still very complex compared to, for example, a typical Scottish process, of a mash and maybe two sparges.
Mash number barrels strike heat mins stood tap heat

Three types of hop graced the copper: Kent from the 1907 and 1909 harvests and Sussex from 1908.

No ageing for this beer.
