Did You Know...Guinness

Guinness Stout is the happy result of a wily brewmaster's tax dodge, says Greg Kitsock in The Washington Post. back in the 19th century, Arthur Guinness Jr. tried to save money by skimping on highly taxed barley malt. Instead, he substituted about 10 percent of the barley malt with untaxed, roasted, unmalted barley. That pinch of roasted barley "gives Guinness its color and its burnt, coffee-like flavor with an acidic note to the finish."

Guinness measures 4.2 percent alcohol by volume, and has 125 calories per 12-ounce serving. Budweiser, by contrast, is about 5 percent alcohol and has 147 calories.
