Beer
Beer is one of the oldest and most widely consumed alcoholic drinks in the world.
It is brewed from cereal grains, most commonly malted barley, though wheat, maize (corn), rice, and oats are also used.
Most modern beer is brewed with hops, which add bitterness. Other flavouring agents such as gruit, herbs, or fruits may be used instead of hops.

All beers are either lagers or ales, determined by the type of yeast used during the fermentation process.
Lagers are made with yeast that ferments at the bottom of the beer mixture.
Ales are made with yeast that ferments at the top.

Ale is the oldest style of beer, which dates back to antiquity. It’s a general category of beer, you’ll find sub-categories like: brown ales or pale ales.
Ale is accessible for home brewers. It needs warm-temperature fermentation for a relatively short period of time.
Lagers are a newer style of beer with two key differences from ales.
Lagers ferment for a long time at a low temperature, and they rely on bottom-fermenting yeasts, which sink to the bottom of the fermenting tank.
