If my information for pre-war Scottish Stout was limited, for the war itself it’s nigh on non-existent. With the one exception of William Younger, for whom I have data aplenty.
I have analyses from just two breweries, and all are from 1939.
Not sure that tells us much. I’ll move quickly on to William Younger.
Over the course of the war, DBS suffered multiple cuts to its gravity. Between 1939 and 1944 its OG fell from 1066º to 1051º - a reduction of almost 25%.
The surprise is in the hopping. In 1939, it was 6 lbs per quarter (336 lbs) of malt. Which for Scotland was pretty high.
During the war, brewers were told to reduce their hopping rate various times. Having become totally dependent on domestically-grown hops, once the size of the harvest was known, brewers were told how many they could use in the coming year as a percentage of their pre-war use.
It’s unusual to see a hopping rate almost unchanged in by 1943. Having looked at the situation with other Younger beers, this wasn’t the case across the board. The reduction in other styles is greater. Even though Younger, who was hopping at a rate below 1 lb per standard barrel, were exempt from the cuts.
Don’t pay too much attention to the FGs in the table. Younger’s brewing records only list the cleansing gravity, not the racking gravity. The real FG would have been several degrees lower.
