Youngs boiling and fermentation in 1940

Yes, I'm still away on holiday. How selfish of me. Going away creates so much work for me. Lining up more than a dozen blog posts before I leave. Then writing the same number of travel posts when I return. It's all very time-consuming.

Boiling times are basically the same. Two hours, for most boils, for most beers. Only the watery A got a little less. And the strongest beer, XXX, got a little longer.

More surprising is that the fermentation temperatures have been reduced. The pitching temperatures are, on average, 1.5º F cooler and the maximum temperatures 4 º F. 

Despite the lower fermentation temperature, the fermentations lasted a day less. Which doesn’t make a whole deal of sense to me. The small drop in gravities wouldn’t have been enough to make that much of a difference.
