Beer is a beverage that has four ingredients, which are Barley, water, hops and yeast. The basic idea is to extract the sugars from grains such as barley, so that the yeast can it into alcohol and carbon dioxide, thereby creating beer.
The brewing process starts with grains, which go a process of heating, drying out and cracking. The main goal at this stage is to isolate the enzymes which they They are then steeped in hot, but not boiling, water for about an hour, which activates the enzymes in the grains, causing them to break and release their sugars. At this point, the water, which contains all the sugars from the grain, is drained. This is a sweet sticky liquid, and is the basic of beer. This liquid is boiled for about an hour while hops and other spices are added for flavouring, and to as a natural preservative. The final step requires the liquid to be cooled, strained and filtered, before yeast is added to begin the fermentation process, which changes the sugars into alcohol. Finally, the liquid, which is now beer, is stored for a of weeks at room temperature while the yeast works its fermentation magic. Cheers!
