Unfortunately, unlike some other beer ingredients, such as hops, sugar was also useful as a human food. Which meant supplies to brewers were limited. A bad harvest in the West Indies in 1940 didn't help. This prompted a cut in both the domestic sugar ration and the quantities allocated for industrial use.
In 1940, the UK had 1.25 million tons of sugar of imported sugar to play with. It came from all over the British Empire. Wonder how much of that was used in brewing? Of course, you do. And what better way to convey the information than a nice table.

Around 70,000 tons of sugar were used in brewing in 1940 and 1941. That was about 25% less than in 1939. And about 5 or 6% of all that sugar coming in from the West Indies, South Africa and the Pacific. Not that big a proportion, really. Then again, there were all those cakes, biscuits and cups of tea that needed sugar.
It’s worth noting that the 1.25 million tons wasn’t the total sugar supply. That’s just cane sugar. There was also UK-produced sugar from sugar beet.
The average amount of sugar used in beer fell during the war. From around 15% in the late 1930s to 10 or 11% after 1940. What the hell. Here's another table showing that:
