It’s beer that made Milwaukee famous — and in this hour, live from Milwaukee, Wisconsin, Ira and guests raise a glass to the science of brewing beer. How do yeast, water, hops and grain combine to form a lager, pilsner, or ale?
The steps in the brewing process seem simple: malting (allowing the barley to partially germinate followed by a roasting process), mashing (heating the grain in water, to convert some of the starches into sugars), and fermentation (converting the sugars into alcohol). But the actual process is quite complicated, requiring tightly-controlled conditions supervised by a master brewer. You need the right temperatures, the right times, and the right ingredients to get that brew to turn out right.
