The basic ingredients for beer are malt, yeast, hops and water. Breweries have their own variations but, basically, the malt is first placed in a mashton, where it is mashed for an hour, to which boiling water is added. The extract of this goes to a tank, where it is boiled for about two hours. The variations are added after this — wheat for wheat beer and so on. Two kinds of hops are then added, one for aroma and the other for bitterness. The resultant mixture, called wort, is pushed into a fermenting vessel with yeast. It stays here for 18 days while the temperature, ph content etc., are monitored. And the brew finally emerges as beer in a pitcher or mug. The brew master is the crucial player here, as he decides on the fine balance of ingredients for the perfectly brewed beer.
