I was surprised to discover that I remember some of my year in Germany. Specifically, some of the parts in Munich. I was busy trying to learn why, in all of Germany, I was stuck in a town with some of the worst local beer in the country. I had a friend, wiser than I, who had decided to spend a year in Munich. This gave me a great excuse to visit every once in a while.
German beer is good, Munich beer is divine.
Although I could spend hours espousing the popular Pilseners, not to mention the stories resulting from said Pilseners, I'm going to concentrate on the Hefeweizens. Beer is made from malt, generally barley malt. On the other end of the scale, you can use wheat. Wheat tends to be a little more difficult to brew with, as it has no husk, like barley does. Hence, it is almost always used in conjunction with barley, for manageability purposes.
