What is Beer?
What is beer?
Brewing is the process of extracting raw materials with water, boiling them (usually with hops), and fermenting the resulting liquid into an alcoholic beverage. The brewing process takes a long time, requires a lot of work, and is a combination of science and art.
The ingredients that make up beer include water, yeasts, grains or malts, and hops. Together, these four simple ingredients can form an array of delicious, unique flavors and styles of beer.
Yeast: The main type of yeast used in brewing is called brewer’s yeast, which can convert fermentable sugars into alcohol. A single strain of yeast can produce hundreds or even thousands of bottles of beer.
Grains or Malt: Barley, wheat, rye, and oats are the primary grains used in making beer. These grains generate a high concentration of starch-digesting enzymes that transform natural starches into sugars and alcohol during the brewing process.
Mashing: Grain, along with a small amount of water, are placed in a vessel called a mash tun to begin the fermentation process. Enzymes in the grain metabolize the complicated starches in the malt to create sugars that brewers later turn into wort, or fermented liquid.
Hops: After the mash has been completed, a small amount of hops is added to the wort to give the finished beer its bitterness and aroma. They also have a preservative effect, helping to protect the beer from bacteria.
The term “beer” refers to all kinds of alcoholic beverages that are made from grains and malt, including lagers, ales, and bitters. In most countries, a beer must contain a minimum of four ingredients to be legally classified as beer: namely water, yeasts, grains or malts, & hops.
