“Beer here! Get your ice-cold beer here!” You probably heard that shouted the last time you were at the ball park. At a ball game, a party, a barbecue, or a fishing trip, people enjoy an ice-cold beer. Throughout the world, people drink 22 billion gallons of beer annually. Americans alone consume 24 gallons of beer per person every year. Few people know how beer is produced, however. The basic brewing process has five steps.
The first step is mashing. Cereal grains, usually barley and hops, are mixed with water. The mixture, called “wort,” is heated to about 150 degrees and stirred constantly. When the mixture is allowed to settle, the solids settle and the liquid passes through it.
Then comes boiling and hopping. During these steps, dried flowers from the hop vine are added, about three quarters of a pound of hops for every 31 gallons of wort. The hops prevent spoiling and give the beverage flavor. The mixture is boiled for about two hours.
Next comes the fermenting stage in the process. The brewer uses yeast to cause fermenting, adding about one pound per 31 gallons of wort. Alcohol and carbon dioxide form during fermentation. The mixture is kept at 38 degrees Fahrenheit and completes fermentation in about a week or two.
The final step is called “finishing.” Here, the brewer compresses and stores carbon dioxide from the beer wort. Stored in huge metal vats for three to six weeks, the beer continues to settle and clear. Then the beer is carbonated and passes through a pressure filter to be packaged.
Perhaps the next time you have a beer, you'll appreciate it more. Even if you're not a beer drinker, you'll realize the work that went into producing one of the world's best-selling
