What is beer?

Beer is an alcoholic beverage brewed from malted grains, hops, water, and yeast. The grains provide the sugar needed to ferment into alcohol, while hops give beer its distinct bitterness and aroma. Yeast is used to turn the sugars in the grain into alcohol. In addition, many types of beer rely on additional ingredients such as fruit juices or spices, but the core ingredients remain the same.

Origin of beer

Beer has been brewed since ancient times, with some of the oldest known recipes dating back to around 7,000 BCE. Beer was an important part of many cultures; it was often used in religious ceremonies and even consumed as a daily drink. Over time, brewers discovered ways to improve their beer by using different types of grains, hops and yeast. This allowed them to create a variety of different beer styles, from dark and malty Bavarian lagers to bright and fruity Belgian ales.

What is beer made of?

The four typical main ingredients of beer include water, barley, hops, and yeast.


Water is the most important ingredient in beer as it makes up more than 90% of what’s inside your glass. Different types of water can affect the flavor and style of a beer, so breweries often use filtered or mineral-rich water to give their beers an added edge.


Malted barley is what gives beer its characteristic flavor and color. Barley is what provides the fermentable sugar needed for yeast to create alcohol during fermentation. Different types of barley can be used in different beer styles; from light, pilsner malt in German lagers to roasted malts in dark ales.


Hops are what give beer its bitter flavor and aroma. Hops are the flower of a plant related to cannabis and can be used fresh or as hop pellets. Different hop varieties can impart different flavor profiles, from floral and citrusy American Cascade hops to spicy and earthy British East Kent Goldings.


Yeast is what turns the sugars in the malted barley into alcohol during the fermentation process. Different types of yeast will affect the flavor and aroma of beer, with lager yeasts producing crisp, clean tasting beers while ale yeasts give off fruity flavors.

Rounding out what is in a beer are other ingredients such as fruit juices, spices, honey or sugars that can be used to create unique flavors.

What is the beer brewing process?


The brewing process begins with milling, which is the crushing of the malted grains in order to release their starches.


Once the grain is milled, it is mixed with hot water and boiled in what’s known as a mash tun. During this boiling process, hops are added to give the beer its bitterness and aroma.


Once the boiling process is complete, the liquid (now known as wort) is cooled and transferred to what’s known as a fermenter. Yeast is added to this mixture, which then begins the fermentation process where it turns sugars into alcohol and carbon dioxide gas.


Once the beer is fermented, it is transferred to what’s known as a conditioning tank. In this tank, the beer will mature and develop its flavor and aroma. This can take anywhere from one week to several months depending on what type of beer it is.


The final step in the beer making process is packaging. This involves transferring the beer from the conditioning tank into bottles, cans or kegs depending on what type of beer it is and what format it will be sold in.

Two main types of beer


Ales are what’s known as top-fermented beers. This means that the yeast is added to the fermenter and rises and ferments at the top of the liquid, producing what’s known as an ale beer. Ales tend to be fuller-bodied than lagers with more intense flavors and aromas.


Lagers are what’s known as bottom-fermented beers. This means that the yeast is added to the fermenter and sinks to the bottom of the liquid, producing what’s known as a lager beer. Lagers tend to be lighter in body than ales with more subtle flavors and aromas.
