Beer Brewing Ingredients
Beer in its basic form is made from just for ingredients: water, malted grain, hops and yeast.
Water provides the base for all beer, though various minerals in the water contribute flavor and character to the beer. Malted grains provide sweetness, color and body as well as provide the sugars for the production of alcohol. Hops primarily contribute bitterness to the beer, though they also provide flavor and aroma. Yeast is used to ferment the malty sugars into alcohol, and also to contribute flavor and character to the finished beer.
In addition to the four basic ingredients, a variety of flavor and other miscellaneous additives can be used in the brewing process to improve clarity, spice, add flavor and otherwise enhance the beer.
