In the 1970s, draught Stout meant one thing: Guinness. In most of the UK, draught Stout died out between the wars. The exceptions were Northern Ireland and London. In the capital, it managed to hang on until sometime in the 1950s.

A large percentage of brewers were still producing a Stout at the start of the 1970s. Mostly, these were pretty low gravity, sometimes as low as 1030º. Coupled with a low degree of attenuation, it left these beers with less than 3% ABV.

Let’s take a look at some of the Stouts being brewed at the time.

Quite a variation in gravity there. But the outlier – Extra Stout – differs from the others in being purely an export beer. All the others are in the 1030ºs.

The rates of attenuation are all over the place. The Whitbread and Adnams Stout have a normal 75%. (Though it should be borne in mind that the Mackeson in the table is before the addition of lactose.) While the Truman and Fremlin examples are both under 60%.

It’s no surprise, then, four of the seven examples are below 3% ABV. Truman’s is even under 2.5% ABV. Lovely and watery with no kick of alcohol. Yum.

There’s also quite a spread in the hopping rates. Ranging from 3.5 lbs per quarter (336 lbs) of malt to almost 6.5 lbs. That’s quite a difference.
