"Beer is made of barley and hops. But why is a hop called a hop? No-one on the Hop Route in George was able to tell me, and even a dictionary of etymology (the history of words, Miranda) was tantalisingly vague. Seeing that hops were first grown about a thousand years ago in the area of Europe now called Bavaria, it is likely that it comes from a Teutonic word 'hoop' (heap) which indicates the way in which hops were left to dry.
