Let's Brew Wednesday - 1959 Adnams XXX

It’s May, the weather is wonderful – what could be more appealing than a nice watery 1950’s Mild?

And this version of Adnams XXX Mild, at under 3% ABV, is certainly pretty watery. Though perhaps not quite as watery as it looks. I have a Whitbread Gravity Book analysis for Adnams Mild from 1967 and that lists the OG as 1033.5º.  Yet a brewing record from the same year gives the OG as 1031º.

Why the discrepancy? Probably because of primings. Most breweries don’t bother listing them in the brewing record. When they do, 2º or 3º is typical for the gravity boost primings give to a beer of this gravity. Primings probably account for the difference between the calculated colour and the one given in the analysis, which is around 20 SRM.

To simulate this, you could add another 0.5 lb of No. 3 invert at racking time. That should get you somewhere near the colour and effective OG.

It’s surprising how different this recipe is from 1950 XX. The earlier beer contained amber malt and caramel, but no pale malt.

I know little about the hops, other than that they were English and from the 1957 and 1958 harvests.

I assume primings were still counted for tax purposes?

yes. Sometimes brewing books have entries for the primings.
