It helps to pick a period and work through that. 1945 to 1959 seemed a good place to start. As I’ve been paying that particular attention recently. With a vague plan somewhere in the back of my head about eventually writing a book on the immediate post-war years. Not sure when that will happen. But it’s handy to have some sort of focus.
At the start of WW I, Adnams brewed two Stouts, BS (presumably Brown Stout) and DS (Double Stout) at 1055º and 1060º respectively. The weaker Stout was a casualty of the war, with my last sighting of it in early 1917. DS, on the other hand continued to be brewed through the war and the post-war period. Though by the eve of WW II it’s gravity was down to 1042º, quite low for the period.
WW II knocked some more of the stuffing out of DS, with the gravity down to 1039º by 1945. The pain didn’t end there. Gravities continued to fall after the end of WW II and in 1948 DS was just 1037º. It hit 1040º again in 1950, but after that continued to fluctuate for the rest of the decade, ending it at 1037º. Or exactly average gravity.

After the war the rate of attenuation was fairly constant at around 66%, leaving it mostly under 3.5% ABV. The pre-WW I version had a more usual rate of attenuation, 75%, and was around 6% ABV. But don’t start thinking DS was a Sweet Stout. It was hopped at about the same rate as a Pale Ale of the same gravity: 1 lb. of hops per barrel.
Moving on to the grist, one thing is immediately apparent: Adnams didn’t usually employ any adjuncts. With the exception of the war and its immediate aftermath when brewers were obliged by the government to use flaked barley. Though even then it didn’t always make its way into DS.

The grists are fascinating. Kicking off with a combination of base malt plus amber, crystal and chocolate malts. Until 1954, when the amber malt was dropped and the chocolate and crystal malt content raised. It’s unusual to see amber malt in Stouts – or indeed anything else – after WW II. And usually black malt was the roast of choice. I’m not surprised at the lack of brown malt. It was pretty much limited to London by then.
The sugar content is a pretty constant 10%, though the types vary. Starting with No. 3 and tintose, which I assume is a form of caramel. In 1954 the tintose was replaced by CDM, which I believe is a caramel-heavy proprietary sugar. In 1958 Hydrol, which might be a form of glucose, came in for No. 3 invert.
There’s almost nothing I can say about the hops, other than that they were always all English. No varieties or even region of origin are specified in the records. It’s no surprise that they are all domestically-grown hops. Britain imported almost none in those years.
What next? Adnams Pale Ales maybe.
