Johann Sebastian Bach wrote a short opera about coffee obsession. The famed Baroque composer and pianist, was also a notable coffee fiend. Though he's not well regarded for his humor, he turned an amusing poem by his frequent collaborator, Picander, into The Coffee Cantata in 1732. The cantata mocked public outcry about the rise of the Vienna coffeehouse scene. At the time, coffee was regarded as a dangerous societal "vice."
