An alcoholic beverage made from barley, water, yeast and hops. Most hikers crave it, but since there is no dehydrated form, few hikers carry it. Beer cannot be burned in backpacking stoves and must be metabolized by the body. Though useless for cooking, it often causes joy. Beer can lead to mental and physiological changes that range from pleasant and fuzzy emotions to complete and even catastrophic muscle relaxation. Should be taken orally.
