What is beer?
Beer is an alcoholic beverage made from one or more malted cereal grains such as barley, wheat, oats and corn. Brewers ferment these grain grains with yeast, which converts the sugars in the grain into alcohol and carbon dioxide. The type of beer you drink depends on the ingredients, brewing methods and the brewery from which it was brewed.
The basic ingredients of beer are water, malt, hops and yeast. During a brewing process, these four ingredients are combined with flavorings and added to a boiling liquid to create your favorite brew.
When the brew is complete, it’s time to start fermentation. Fermentation is a two-part process: primary fermentation is the first step, and secondary fermentation is the last. During the first, the yeast converts the sugars into alcohol and carbon dioxide, which gives your beer its signature fizz.
Yeast is the secret ingredient that unites all the other ingredients and transforms them into your favorite beer. There are hundreds of different types of yeast, and many brewers believe the strain they use is the most important element in determining the beer’s character.
Brewers also make use of other elements to enhance the taste and aroma of their beer. For example, the type of grain they use and how it is roasted contributes to its flavor.
The type of water used in the brewing process is very important as well. The brewers will adjust the brewing water to make sure it has the right minerals, such as magnesium and calcium, for the style of beer they are making. For example, soft London water is ideal for stouts, while sulphur-rich Burton upon Trent water is perfect for bitters.
