Let's Brew Wednesday - 1944 Adnams XX

Having started the war at 1029º, XX had little scope for getting much weaker. Especially if you understand how the tax system worked.

Tax was charged on a “standard barrel” – 36 imperial gallons at 1055º. A weaker or stronger beer was charged at a proportional rate. Thus two barrels of 1027.5º made one standard barrel. But there was a restriction. The minimum rate of tax was the equivalent of a 1027º beer. So if you brewed a beer at 1020º, you paid tax as if it were 1027º. Clearly this was a financially unattractive move. Making 1027º the weakest anyone ever brewed.

The biggest change from the 1943 recipe is the replacement of flaked oats by flaked barley. This was a change once again dictated by the authorities. Breweries had to use a certain proportion of flaked barley whether they wanted to or not.

With two coloured malts, the grist is quite unusual for a Mild. Few contained anything darker than crystal and often not even that.

The hops were exactly the same as in the PA, that is English from the 1942 and 1943 harvests.
