Beer is the most consumed alcoholic beverage in the world. After water and tea, it is the 3rd most popular drink worldwide. It is made via the saccharification of starch and by fermenting the sugar that results; yielding beer. Malted grains, (usually barley and wheat) and hops, produce the flavors in beer. Hops add bitterness and acts as a preservative, although flavoring with herbs and fruit may also be done. See Beer flavor characteristics here. Class is in Session. Drink Up!
