Barclay Perkins also employed a wide range of non-malt fermentables, six in all.
Every beer except the two poshest – PA Export and KKKK – had some flaked maize in the grist. With the Mild Ales containing rather more than the other styles. Flaked maize was a pretty standard ingredient, occurring in the overwhelming majority of brewers’ beers. 10% - 15% is a pretty typical proportion.
At around 10%, the total quantity of sugar in the Mild Ales is towards the low end of typical. The principal type, however, is, however, totally typical: No. 3 invert. Used for both colour and flavour, it was important in achieving the expected character of a Mild. After colour correction, the dark versions would have contained a slightly greater proportion of caramel.
The other sugar which pops up in the Mild Ales and DB is something called “BS”. It could simply be brown sugar.
I was so surprised by the percentage of No. 3 invert sugar in the Pale Ales that I went back to the brewing records to check. I would have expected No. 1 or No.2, especially in those quantities. Checking back through the brewing records, it appears that they switched from No. 2 invert to No. 3 in 1937.
KK once again shadows the Mild Ales, though without any BS. While its stronger siblings are out on their own with No. 2 invert.
Brewed from just pale malt and No. 1 invert, PA Export must have been relatively pale, especially for its gravity. Its simple grist is reminiscent of Pale Ales from the 19th century.
