What Is Beer Made Of? – 4 Main Ingredients

You might not be a beer aficionado, but you still know how much you love that cold refreshing taste of beer. But what is beer made of? You don’t have to be a brewmaster to know how to make your own beer or to appreciate its delightful flavor.

Beer is an interesting beverage with an even more interesting background story. I’ll start at the beginning, and answer the question, ‘What is beer made of?’

The Meaning of Beer

Beer is a beverage made from fermented grain that’s been brewed with hops. The most common beer ingredients are barley and hops, although other grains such as wheat and rice may be used. Other ingredients such as herbs and fruits may also be added to produce different styles of beer.

The earliest known production of beer took place in ancient Egypt, where it was used by laborers for energy during construction work. Ancient Sumerians were also known to brew beer from barley.

In the Middle Ages, brewing became more popular in Europe and was often a family business passed down through generations. Some breweries have been producing beer continuously since those times; others have been acquired by larger companies or merged with other breweries over time.

Today, beer remains one of the most popular alcoholic beverages in the world with over 2 billion gallons consumed every year in America alone!

Now that you know the definition of beer, stay tuned to see what types of beer there are and what is beer made of.

Beer Varieties

There are many different types of beer to choose from, with new ones popping up all the time. Here is a list of the most common types of beer:


There are many types of beer, but the most common type is lager. Lagers are made with a combination of malted barley, water and hops. Lager is an old German word that means “to store.” The term originally referred to the process of lagering a beer for several weeks to months at cold temperatures (around 40 F) before consumption.

Pale ales

Pale ales are also very popular. Pale ales use malted barley as the main ingredient, but they also contain other grains such as wheat or oats. These beers have a higher percentage of hops than lagers do, which gives them a slightly bitter taste and aroma.


Stout is another type of beer that uses roasted malts as its main ingredient. The roasting process gives stout its dark color and full body taste that makes it one of the most popular types of beer in America today.

Wheat beer

Wheat beer is made with pale or amber wheat malt. Some examples of this style include Hoegaarden, Blue Moon, and Heineken.

Fruit beer

These beers are brewed with real fruit. Some examples of fruit beers include Blue Moon’s Raspberry Wheat, Red Stripe’s Pineapple Lager, and Leinenkugel’s Summer Shandy.

Sour beer

Sour beers are brewed using bacteria that result in a tart flavor. They are often fermented in barrels or tanks which also contributes to their unique flavor profile. Examples of sour beers include Rodenbach Grand Cru and La Folie by New Belgium Brewing Company.

Above we have introduced about beer and types of beer, keep watching to know what is beer is made of.

What Is Beer Made Of?

Beer is made with a variety of ingredients. The main components of beer are water, yeast, malted barley and hops. Other ingredients may be used for various purposes in certain styles of beer.


what is beer made of- Grains

Beer is made of grains. The three main grains used in brewing are barley, wheat and rye. Other grains are sometimes used as well, such as corn or rice.

The barley grain is the most important ingredient in beer because it gives it its color, flavor and aroma. The barley is malted, which means that it has been germinated (sprouted). This makes the enzymes that are present in the grain more active so that they can convert their own starches into sugars for fermentation.

After harvesting, the grains are dried to remove excess moisture before being milled into flour. Milling removes the husk from the grain but keeps some of its outer layers intact so that enzymes can still work on converting starches into sugars during malting.

The process of milling also exposes more starch granules to water molecules for easier conversion into fermentable sugars during mashing.


Hops are the flowers of a climbing vine that is related to cannabis. Hops grow best in the cool climate of the Pacific Northwest and Northern Europe, particularly the United Kingdom. They grow quickly, reaching full maturity in about 6 weeks. The flowers have a mild, grassy aroma and are used as an ingredient in beer to add flavor and bitterness.

Hops are usually added to boiling wort or unfermented beer as a flavoring and stability agent, though they also have uses in some other beverages. The compounds that give hops their flavor and aroma include alpha acids (humulones), beta acids (lupulones), essential oils, resin, and lupulin.

The alpha acids in hops are what make them bitter, but they also provide stability to beer by preventing spoilage organisms from growing. The more bittering hops you use, the more stable your beer will be over time because it will take longer for these “bad” organisms to grow out of control.

Those are two very important ingredients to make beer. They have partially answered your question about “what is beer made of”. Would you like to know more? Let’s continue to learn together.


Yeast is a single-celled microorganism that converts the sugar in beer into alcohol, co2 and flavor compounds. Yeast is a living organism, so it needs to be cared for properly. Most brewers use liquid or dry yeast that can be purchased from homebrew suppliers.

Yeast should be stored in a cool, dark place between 50F and 70F (10C-21C). Yeasts are very sensitive to temperature and will die if exposed to heat over 80F (27C) for more than a few minutes. Yeasts can also die if they get too cold; they should never be stored in the refrigerator.


Water is the main ingredient in beer. The water used in the brewing process, called brewing liquor, is usually obtained from a municipal source. The quality of the water used in brewing can have an important effect on the flavor and character of the finished beer.

Brewing liquor should be free from bacterial contamination, suspended solids and other particulates. The pH level should be within the range 5-8 to prevent excessive extraction of tannins from malt husks during mashing. If necessary, salts may be added to raise or lower pH levels. Brewing liquor should also be free from chlorine which could react with phenolic compounds in malt to produce chlorophenols that impart a medicinal taste to beer. Chlorine can be removed by boiling for 20 minutes, then allowing the water to cool overnight before use.

Water is an essential ingredient in beer. It accounts for 90 percent of the total volume and 95 percent of the total weight of beer. Water has a profound effect on the quality of beer. It influences the taste, mouthfeel, color and clarity of beer.

Above are the 4 main ingredients of beer to answer the question “What Is Beer Made Of”, let’s continue to learn about other minor ingredients.

Additional Beer Ingredients

what is beer made of - Additional Beer Ingredients

Other ingredients can be added to beer after fermentation. These ingredients may include fruit, vegetables and spices. The most common additional ingredient in beers is yeast, which helps give the beer its flavor.

The following list contains some common additional ingredients that are used in brewing:

Fruit: Fruit can be added at several stages during the brewing process. It may be added directly into the mash or added during fermentation for secondary fermentation. Fruit can also be added before bottling for carbonation purposes or added after bottling for flavor purposes.

Vegetables: Vegetables have been used in brewing for centuries as a way of adding extra nutrition at meal times. Today brewers are experimenting with vegetables such as tomatoes, peppers and even carrots as an alternative to using fruit in their recipes.

Spices: Spices are often used in combination with fruit or vegetables to add flavor to a particular style of beer. Commonly used spices include coriander seed, orange peel or dried cham.

Those are all ingredients that create beer, which is the answer to the question “What Is Beer Made Of?” Do you wonder how they work together to create beer, let’s find out.

How Do All the Ingredients Combine?

There are many different types of beer, but all beers have five basic ingredients: water, malted barley, yeast, hops and a flavoring agent. Each ingredient has a specific role to play in the finished product.

  • Water is the most essential ingredient in beer. It accounts for 90% of the brew by volume and provides a base for all other flavors.
  • Malted barley provides the sugars needed to create alcohol and carbonation during fermentation. It also imparts flavor notes that make each type of beer unique, such as caramel or bread crust.
  • The yeast converts sugars into alcohol during fermentation and carbon dioxide during bottling conditioning and aging (for bottle-conditioned beers). Different strains of yeast produce different types of flavors in the finished beer — some fruity, some spicy or peppery, some clean and neutral.
  • Hops contribute bitterness to balance out sweetness from malt; they also provide aromas like piney or citrusy notes that complement other flavors in a particular style of beer.

The above is all related to the brewing ingredients. They answered your question about “what is beer made of”. Do you want to know more about the beer making process? Let’s continue to learn together.

How Is Beer Made – Brewing Techniques

Beer brewing is the process of making beer by steeping a starch source (commonly cereal grains) in water and fermenting it with yeast. The conversion of starch to sugar is achieved through the action of amylase enzymes during mashing. Yeast consumes the sugars and converts them into ethanol and carbon dioxide, which are then often converted to other beverages such as wine or distilled spirits. The whole brewing process takes place under controlled temperatures.


Milling or grinding is the crushing of raw grains into a powdery consistency that allows them to be soaked in water. The milling process allows for better extraction of fermentable sugars from the grain.


Mashing is the process used to convert the starch in grain into fermentable sugars that can be consumed by yeast. The most common mashing method involves mixing crushed malt (malted barley) with hot water in a mash tun until the temperature reaches approximately 150°F/65°C, at which point enzymes present in the malt convert starches into sugars. This is known as saccharification, which can take up to two hours at this temperature depending on how much enzyme activity occurs during this time period.


Lautering is the process of separating the wort from the spent grains. This can be done in a number of different ways, but most commonly it’s done by pouring water over the top of the grain bed in your mash tun, allowing it to pool up at the bottom, and then draining that liquid into your boil kettle.


Boiling is when you heat your wort to a specific temperature for a specific amount of time. The purpose of boiling is to sterilize your wort, which helps prevent any potential infections from occurring during fermentation. It also helps break down proteins and carbohydrates into simpler compounds like amino acids, which are easier for yeast to consume during fermentation.


Cooling is when you lower the temperature of your wort from boiling (212°F) down to pitching temperature (65-75°F), which is important because if you pitch too hot it can cause off flavors like DMS, or dimethyl sulfide, as well as inhibit yeast growth.


Fermentation is the process of making beer by adding yeast to a sugary liquid. Yeast consumes the sugars and produces alcohol and carbon dioxide (CO2). The CO2 bubbles to the surface of the brew, creating foam. It’s at this stage that beer is called “uncarbonated” or “still.” During fermentation, yeast also produces many esters, which are responsible for much of the flavor in beer.

Above are the basic steps for beer production, the main ingredients that answer the question “what is beer made of ” have been used. Next we continue to follow the completed stages in beer production.


Conditioning is the process of carbonating beer after it has been brewed. Carbonation occurs when CO2 is forced into the liquid under pressure. This can be done in bottles or kegs using special equipment called a carbonator or keg jacket. After conditioning, the beer will be ready for packaging and serving at your local pub!


what is beer made of - Packaging

The final step in the brewing process is packaging, which involves transferring the beer from the fermentation tank to a bottle or keg. This can be done manually or with automated equipment.

Bottling: For homebrewers who want to create their own shelf-stable bottled beer, there are three options: traditional crown cap bottles, swing-top bottles or growlers (a refillable half-gallon container). Each option has its pros and cons. Crown caps are the easiest – no capping machine required – but they work best on bottles that are clear glass and have smooth sides; some brewers prefer to use swing-tops or growlers because they leak less than crown caps do.

Kegs: When you buy beer from a keg at a bar or restaurant, you’re actually buying a half barrel (15.5 gallons) that’s been split into smaller units using a “beer gun.” Kegs come in several different sizes and can be used for anything from small batches of homebrew to commercial batches of craft beer.


What is beer made of? Although there are many different variations of beer, the basic ingredients of beer are water, hops and grain. The recipe for a good beer is simple but the making of the beer can sometimes be complex.

If you love to drink good beer, then you know how great it is to sit down with a glass of your best brew and have a conversation. Whether you are just friends, co-workers or family members, beer is the perfect choice for a relaxing time together.
