Beverages The Story of Coffee at Lothian Life. The textual equivalent of those videos which would appear through the square window on Play School:

"What really gives coffee its aroma and flavour is the way the beans are roasted. Heat breaks down starches in the bean, changing them to simple sugars. As the roasting process continues, aromatic oils, acids, and caffeine weaken but other oils start to develop, in particular caffeol, which is largely responsible for coffee’s aroma and flavor."

I probably drink too much coffee though it is my only toxic vice; I don't smoke and only drink sporadically. It is worrying to note from that article that although physically it has all kinds of benefits like all drugs it does nothing for your psychological outlook. Water?
