Brewmaster Joachim Rösch walks into a cloud of steam outside a factory at the Ganter Brewery in Freiburg im Breisgau, Germany. (Joachim Rösch is featured in the book What I Eat: Around the World in 80 Diets.) The caloric value of his day's worth of food in March was 2700 kcals. He is 44 years of age; 6 feet, 2 inches tall; and 207 pounds. Joachim's job requires him to taste beer a number of times during the week, and unlike in wine tasting, he can't just taste then spit it out: "Once you've got the bitter on the back of your tongue, you automatically get the swallow reflex, so down the chute you go," he says.
