How Beer Is Made

Beer is made from a combination of yeast, grain, water and hops. Each of these ingredients contributes different flavor and aroma to the finished product. A beer can range in color from clear to dark, depending on the type of malt used.

Depending on how much alcohol is in the beer, it can also have various flavors. Pale ales, for example, have a hoppy taste and a bitter aftertaste. Pilsners are typically characterized by spicy and floral aromas. Some beers can be cellared, so they can age over time.

Alcohol content in beer can vary from less than three percent to over 14 percent. The final alcohol content is determined by the amount of sugar in the wort. Increasing the amount of wort sugar increases the alcohol content.

The yeast that is used in the fermentation process converts the sugars in the wort into alcohol and carbon dioxide. Dry yeast has a shelf life of several years, while liquid yeast has a shelf life of six months.

During brewing, the beer is cooled before being put into bottles or kegs. Brewers use a variety of techniques to change the brewing process. Variations include multiple yeast additions, barrel aging and blending.

When tasting beer, take a sip to coat your tongue. If you want to get the full taste of the beer, swirl the glass before taking a sniff. Using a two-second sniff will give you a head rush.

The beer you consume can have a positive impact on your health. Studies show that moderate drinkers have a lower risk of cardiovascular diseases. It also has significant amounts of B vitamins and folate.
