How Beer is Made

written by Jean Wandimi 1st October 2014

Beer is made from four prime ingredients: Barley, water, hops and yeast. The idea is to extract the sugars from barley so that the yeast can turn it into alcohol and CO2, creating beer.

Step One: Malting

This is the first step of the brewing where barley is  harvested and processed through a process of heating, drying out and cracking. This is to isolate the enzymes needed for brewing so that it’s ready for the next step.

Step Two: Mashing

The grains are mashed then steeped in hot water for about an hour. The result is a thick paste. This process activates enzymes in the grains that cause it to break down and release its sugars. After this process, people drain the water which is rich in sugar . The liquid that results is called “wort” which is raw beer.

Step Three: Boiling and flavouring with hops.

The wort is boiled for about an hour and spices are added. They  add hops, which are green cone-like fruit of a vine plant. Hops are bitter and they flavour the wort. The bitterness balances the sugar. They also act as a natural preservative.

Step Four: Fermentation

Once boiling is over, the wort is cooled, strained and filtered. It is then fermented in a vessel and yeast is added. The beer is stored for a couple of weeks at room temperature or many  weeks at cold temperatures depending on the type of beer. The yeast  turns the sugars into CO2 and alcohol as waste products.

Step Five: Bottling

The end result is alcoholic beer. However it is still flat and uncarbonated. The flat beer is bottled, at which time it is  artificially carbonated like a soda. After carbonation, the beer is ready to drink.
