During WWII the average coffee ration was ONE pound for every five weeks. That is, unless you were unlucky enough to be a soldier, in which case you were most likely boiling your coffee in a sock, assuming that you could get your hands on the stuff. The Germans were so hard up for coffee that they drank ground nuts instead.
