What is Beer?

Beer is a beverage made from four main ingredients – water, malted barley, hop flowers and yeast. Each ingredient provides a unique flavor and texture to the finished beverage. From mouth-puckering sourness to nutty malty sweetness and floral or fruity hints, there is something for every palate. The alcoholic content of beer can range from as little as 2% alcohol by volume (ABV) to as high as 8%.

The brewing process begins with the preparation of malt, which is ground and steeped in hot water to form the liquid base known as sweet wort. Yeast is then added to the wort and ferments it, consuming the sugars and producing alcohol and carbon dioxide. The resulting beer is transferred to conditioning tanks to age.

Ales are beers that are fermented with top-fermenting yeast and are generally brewed at warmer temperatures than lagers. This helps the yeast to produce more flavor compounds.

Other grains and adjuncts can be used to add additional flavors and textures to the finished beer, ranging from wheat to rye to rice. These grain additions help lighten the body and provide extra fermentable sugars for the yeast.

Yeast is the single-celled organism that does the actual work of converting sugar to alcohol and CO2. Once the fermentation is complete, the brewer adds oxygen to the beer to force out any remaining CO2 and bottle conditions the beer for distribution.
