Washington / DC. (gov) Given what seems to be the ever-growing profusion of coffee vendors, imagine what a crisis it would be if coffee were suddenly rationed. That’s exactly what happened this month in 1942, because the Second World War had interrupted shipments and people were hoarding coffee. But rationing lasted only until the next summer. It’s thought that coffee was introduced into America by Captain John Smith, one of the founders of the Jamestown Colony in Virginia. Its popularity jumped after both the Boston Tea Party and the beginning of Prohibition. For those who don’t make their own coffee, there are just over 19,000 coffee shops across the country, and they sell more than $10 billion worth of coffee a year – according to the U.S. Census Bureau.
