Beer Brewing Steps: What Goes On In A Home Brew

The beer-making process has always been described as a combination of art and science. The method has a precise and calculated quality to it. Beer brewing steps are just that — steps. 

Still, the “rules” and any potential constraints can be hazy, allowing for personal interpretation and the creation of a totally unique beer.

While it might seem intimidating, brewing beer isn’t as complex as you might imagine. 

Brewing beer is fundamentally a simple process with roots dating back 12,000 years. You basically heat water and grain (or extract from grain), then boil the combination with hops, cool it, ferment it with yeast, and carbonate it. 

Of course, that’s the simplified version, but those steps never change. 

So, now we’ll go through each phase of the procedure in greater detail. We’ll begin with the ingredients you’ll need and the different sorts of beer you can make. 

Let’s get started! 

Beer Brewing Steps: The Ingredients You’ll Need

To start your brewing journey, you’ll need to gather your ingredients. Though the amounts vary depending on the style, beer is prepared from water, grains, yeast, and hops. 


Given that beer is composed of up to 95% water, water quality is critical. Water can have various levels of mineral concentration depending on its source. This can have a hefty impact on the flavor of the beer.

It used to be impossible to change the mineral content of a region’s water. This gave water a massive influence over the beer styles that could be prepared in the area. That’s why there are so many beer styles! 

For instance, Stouts are linked with Dublin, Ireland, because untreated water was only appropriate for dark beer brewing at the time. 

English-style pale ales, made famous in Burton-on-Trent, England, attribute their distinct hop bite to the region’s high sulfate concentration. 

In contrast, the high carbonate concentration of the water in southern Germany (Bavaria) required beers to be darker and relatively low in hop bitterness.



The grains I’m talking about here are pretty much the same as the grain used in morning cereals. There’s wheat, rice, barley, oats, corn, rye, and so on. 

Before wheat and malted barley can be used to make beer, they must first be malted (the others do not).

The malting process mimics grain germination, which metabolizes the natural grain sugars (called maltose). These are then fed to the yeast during the fermentation process.

To do so, you have to immerse the seed in water until the plant sprouts. It is then dried in a kiln just as it emerges from the seed. 

Malt can be colored and flavored differently depending on the drying process.

It is the grain that will give your beer three essential qualities, which are: 


The type of malt used determines the beer’s color. Because particular molecules called enzymes transform malt starch into sugar, all beers contain a high proportion of light-colored malts.

Fermentable Component 

It will serve as “yeast nourishment.” Malt sugars provide all of the fuel that yeast eats and converts to alcohol and CO2.

Aroma and Flavor 

These flavors range from mildly corn-like to burnt and mocha-like, with numerous variations in between.


Yeast is the third most critical component of the beer brewing process. Throughout fermentation, yeast consumes the sugars from the malted grain and excretes ethyl alcohol and carbon dioxide.

Brewing yeast is classified into two types: ale yeast and lager yeast. Within each of these groups, there are hundreds of distinct yeast strains. 

Certain strains are more suited to producing certain types of beer. Most brewers believe that the yeast chosen is an essential factor in determining the quality of their beer.

Most yeasts, including ale yeasts, have a more neutral flavor than yeast strains used to produce Bavarian-style wheat beers. 

Lager yeasts are the most balanced of all strains, creating minimal byproducts of fermentation, enabling the malt and hop taste of the beer to shine. 


Hops beer brewing steps

Hops lend beer a robust aroma, a range of flavors, and a gentle-to-strong bitterness that balances the malt’s sweetness. 

They are the blossoms of a perennial vine that resemble soft, green pine cones and contain lupulin, a yellow powder. The resins and oils in this powder are essential for the production of beer.

The bitterness of beer is provided by a hop compound known as alpha acid. Certain beer varieties, such as pale ales, get their flowery, citrusy, and hoppy smells from the oils.

When hops are heated, various chemical changes occur that allow the alpha acid to bitter the beer. The shorter the time the hops are cooked, the less bitter the beer.

There are several hop types, just as there are usually numerous vegetable varieties. Each type has its own distinct flavor and scent.

There you have it, all the ingredients you need to source. These four simple components can be converted into a one-of-a-kind work of brewing art in the hands of a talented brewmaster. 

There are hundreds of beer types, thousands of modern breweries, and tens of thousands of different beers made from these four components. 

The constant influx of new brewers is driving beer inventiveness to new heights. Flavor variations are unlimited when other ingredients like spices or fruits are added.

The Types of Beer You Can Brew 

The Types of Beer You Can Brew

Top Fermenting 

The yeast involved in the creation of ale ferments throughout the beer and accumulates at the top. 

When compared to lager yeast, it has a stronger tolerance to alcohol and ferments at warmer temperatures. Top-fermenting ales include IPAs, stouts, and wheat beers.

Bottom Fermenting 

The yeast used in lager production is more delicate than that used in ale production. It sinks to the bottom of the liquid vessel after fermentation. 

It must ferment more slowly and at lower temperatures than ale yeast, and it has a lesser tolerance to alcohol. 

Bottom-fermenting lagers include Pilsners and Bocks. 

Spontaneous Fermenting 

Lambics and sour beers are created by a process known as spontaneous fermentation. When beer is introduced to wild bacteria and yeast, this sort of fermentation happens. 

These beers emerged from Belgium, but brewers all over the world have discovered methods to tweak the process to make their own sour, quirky brews.

Beers fermented spontaneously include the American sour, Belgian gueuze, and Flanders red ale.

What Goes Into Brewing Beer? 

What Goes Into Brewing Beer - beer brewing steps

Brewing beer involves: 

  • Sanitizing 
  • Malting 
  • Milling 
  • Mashing 
  • Extract separation 
  • Hop addition 
  • Boiling
  • Precipitate removal
  • Cooling and aeration 
  • Fermentation
  • Yeast separation
  • Aging and maturing 
  • Packaging 

I know that seems like a lot, so we’ll break it down in this section. 

The goal of the whole process is to transform grain starches into sugar. Then you’ll extract the sugar with water and ferment it with yeast to create the alcoholic, softly carbonated beverage.

Brewing requires a great deal of science and patience. Varying hops are used for bitterness and aroma, and there are numerous malts to choose from. 

The temperature at which you brew affects the flavor, as does the water used. You can also add additional hops, botanicals, or flavorings.

Step 1: Cleaning and Sanitizing 

The first stage isn’t actually brewing if you already have all of the essential equipment.

To begin, you must properly clean and sanitize ALL of your equipment. This is a critical stage. There shouldn’t be any shortcuts here.

Everything that will come in touch with your beer throughout the brewing process should be thoroughly washed with an unscented mild detergent. 

Then they must be sanitized with a “sanitation-grade” solution. It’s ideal to utilize no-rinse kinds because they make the process easier while still being effective.

It’s time to finally start brewing after you’ve thoroughly cleaned and sterilized your equipment.

Step 2: Choose Your Type of Brew

The brewing stage necessitates your time and full focus for a pretty lengthy period. This is attributed to the necessity of sticking to a fixed timeframe and continuously monitoring the brewing process as it progresses. 

This stage is actually made up of several sub-processes, including mashing, lautering, and boiling, all of which are crucial.

Making every effort to do things right during this period is essential to the overall quality of your product. 

These crucial brewing processes will serve as the foundation for your beer creation. If you make a mistake, it will surely have an impact later on.

It’s not uncommon to make blunders the first few times you learn how to brew beer at home. Do not be discouraged or intimidated by this. 

It is critical that you recognize that this is all part of the learning process and that everyone will make errors in this process.  

Take notes, acknowledge your missteps, and use them as learning opportunities!

Your Main Brewing Methods 

Brewing can be done in three ways: extract, partial mash, and all-grain. As the name implies, the processes differ primarily in how the beer’s foundation is formed, among other things.

Extract Brewing 

Extract brewing essentially utilizes grain extracts, whether dry or liquid or a combination of both, to create the beer’s foundation, known as “wort.” 

This method may also incorporate small amounts of grain to provide depth to the beer. 

Overall, this procedure needs less equipment, space, and time, making it ideal for both rookie and experienced homebrewers. 

Even as they learn and advance, some brewers continue to use extract brewing methods for the sake of convenience.

Partial Mash Brewing

In partial mash brewing, sometimes known as “mini-mash,” malt extract and grain are typically utilized. 

The mix of the two expands your options for creating the flavor, body, appearance, and overall quality of your beer. 

This refined brew is best for folks who have successfully brewed using extract-only approaches. You need to have a firm grasp of the process and want to take things to the next level. 

At the same time, it takes only a bit more time, equipment, and space than extract-only brewing, making the switch simple.

All-Grain Brewing 

All-grain brewing is your final option. This is the purest way of producing beer, but it necessitates more equipment and space (and thus a larger financial commitment). 

You’ll also have to devote more time and have a thorough understanding of the brewing process. 

Because all-grain brewing does not use malt extracts, all sugars are extracted solely from the grains, giving you complete control over your brew. 

As a result, there may be additional potential for errors to occur. All-grain brewing is only for the expert brewer who understands the homebrewing process thoroughly.

Step 3: Mashing 


The next phase in the beer-making process is mashing, which involves transferring the grist, or milled malt, to the mash mixing vessel.  

The mashing process involves blending grain and water, sometimes known as liquor, and heating it to temperatures ranging from 100 to 170 degrees Fahrenheit. 

Mashing causes the malt’s inherent enzymes to break down starches, turning them into sugars and, subsequently, alcohol. 

This procedure takes between one to two hours. Mash temperatures can be steadily increased or let to rest at specific temperatures, both of which are important decisions in the brewing process. 

Different temperatures activate different enzymes and influence protein and fermentable sugar release. 

Proteins also play a limited function but are essential in the formation of froth in the finished beer. Most brewers utilize steam to heat their vessels.

The Difference Between Infusion and Decoction Mashing 

Water and grain are blended in one of two ways: infusion or decoction.

Infusion mashing involves heating the grains in a single vessel (the mash tun). 

Decoction mashing involves transferring a portion of the mash from the mash tun and boiling it in a separate vessel (the mash kettle), then returning it to the original mash. 

Some brewers will repeat this process to obtain double decoction, and a few will go through triple decoction.

Again, the wort is the resulting liquid of sugars and water during mashing. Malt has already been processed into a concentrated syrup or powder consisting of milled grain for extract brewing. 

This is then blended with warm water to form the wort. This is a method commonly used by homebrewers to avoid the extra steps required for removing spent grain from wort.

Step 4: Lautering (Separating The Wort) 

Lautering is the procedure of removing wort as efficiently as possible from spent grain. Typically, it is done in a separate lauter tun. However, mash filtration may now be done by both large and small-scale brewers.

Your lautering tun should have a perforated or slotted bottom. The mash solids settle to the bottom and act as a filter for the wort.

Overall, lautering is a three-step process that includes mashout, recirculation, and sparging.

The mashout involves increasing the mash temperature to 170 degrees Fahrenheit. This inhibits enzymatic processes and retains the wort’s fermentable sugar profile while also making the wort less viscous and simpler to deal with.

The wort is then pulled from the bottom of the lauter tun and recirculated. This allows the loose grain particulates to be naturally filtered out by the grain bed and increases wort clarity.

After the wort has been moved, the spent grain, which consists of grain husks and particles left over from the mashing, must be sparged. 

Sparging is the method of rinsing spent grain with warm water to extract as many sugars from the remaining grain for the wort.

The discarded grain is usually recycled as hog or cattle feed. It can also be used for baking bread!

Step 5: Boiling and Adding Hops 

Following the separation, the wort is transported to a vessel known as the kettle or copper for the boiling process.

This step is required to stop enzyme activity and extract the bitterness value of adding hops.

Many hop (Humulus lupulus) types can be chosen for the bitter and aromatic attributes they contribute to brewing. 

Female flowers, or cones, develop small glands that carry valuable brewing flavorings.

The chemical compounds removed during wort boiling are known as humulones. A percentage of these (the a-acids) is isomerized by heat to generate the related iso-α-acids. This is what gives beer its characteristic bitter flavor.

Originally, dried hop cones were put intact to the boiling wort, but powdered compressed hops are widely utilized because they extract more efficiently. 

Moreover, hop components can be removed using solvents such as liquid carbon dioxide and added to the wort or, following isomerization, to the resulting beer.

Step 6: Whirlpooling 

Whirlpooling beer brewing steps

After a rolling boil, the swirling phase purifies the wort further by eliminating protein and hop particles by settling. 

These solids are referred to as trub. Although the boiling kettle can be utilized as a whirlpool, many brewers prefer to use a separate, specifically built container.

A hop back is a whirlpooling vessel that uses fresh hop flowers or cones in a sealed chamber to filter the trub. You can use this to add extra hop aroma compounds to the wort.

Let’s say you want to use whole hop cones in the boil; you’re going to need a hop back. On the other hand, a traditional whirlpool is more effective in collecting trub produced by hop pellets.

Following that, a heat exchanger is utilized to cool the wort to the temperature required for fermentation. Brewers frequently employ the warm water from this exchange to begin a new brewing cycle.

Step 7: Activating and Pitching The Yeast

After taking your gravity reading, it’s time to add the yeast. This is referred to as “pitching” in the brewing industry. 

You want to make sure your yeast is ready for pitching before starting the brew. Ensuring yeast health is extremely important to consider before starting the brew.

Allow your yeast to rest out at room temperature for about 3 hours before pitching to ensure that it is ready. This will result in better fermentation and, as a result, superior beer.

Brewing Yeasts You Can Use 

Brewing yeast (not to be confused with baking yeast) is available in both dry and liquid forms. Each has its own advantages over the other. 

Either variety is used at the brewer’s discretion. But regardless of which type you use, make sure your yeast is ready for pitching.

Dry Yeast

Dry yeast, which is commonly found in ingredient kits, does not need to be activated but should be kept at room temperature.

Liquid Yeast 

Prior to pitching, liquid yeast will need to be activated by rigorously shaking the container and maybe making a yeast starter. 

A yeast starter will merely prime the yeast for fermentation by allowing it to proliferate.

When your yeast is ready, pitch it into the fermentation tank and aerate the mixture by rapidly stirring with a sterilized spoon or securing the cover and shaking the pot. 

Aerating the mixture is vital because it reintroduces oxygen into the wort that was previously removed during the boil. 

Oxygen is required for yeast growth, which will eventually finish the fermentation process.

At this point, the yeast has been incorporated, and the mixture has been properly aerated. Now, you must secure an airtight lid to the vessel and insert a sterilized airlock or similar blow-off valve. 

This will allow CO2 gases to exit while inhibiting outside air from entering. 

Step 8: Fermentation 


After the wort has cooled, it is transferred to a fermentation vessel, and yeast is added.

It’s here that the magic happens. 

The yeast consumes the sugar, resulting in the production of carbon dioxide and alcohol. To make the type of beer you want, you can add more hops, botanicals, or flavorings.

The time it takes for the beer to ferment is determined by the type of beer being made. Most ales are held at colder temperatures for a short time after being brewed. 

If lager is your choice of brew, the beer is kept at lower temperatures after fermentation for a longer period of time.

Keeping the right temperature during this step is critical for the beer’s flavor, and it’s one of the most difficult tasks for home brewers. 

It is suggested that fermentation be divided into two stages: primary fermentation and secondary fermentation.

Primary Fermentation 

The basic goal of primary fermentation is for the yeast to convert the carbohydrates into alcohol and CO2.

Undesired particles will drop to the bottom of the tank, separating them from the beer. 

Dead yeast cells, extraneous proteins, and hops make up “trub,” which is a collection of these particles. Depending on the style of beer you’re creating, this process will take about a week.

After the yeast has been added to the mixture, respiration must occur before active primary fermentation can commence, which should take about 12 hours. 

For optimal fermentation to occur, keep the temperature between 68 and 72 degrees Fahrenheit.

You’ll detect a discharge of CO2 gas from the vessel after vigorous fermentation has begun. You will see bubbling within the airlock chamber while employing an airlock. 

This indicates that the fermentable sugars are being converted successfully by the remaining yeast.

When bubbling becomes less frequent, it’s a sign that primary fermentation is nearing its end. You’ll have to move the beer to another fermentation vessel at this point.

Secondary Fermentation 

Although the more active stage of fermentation has already occurred during primary fermentation, there are still some fermentables and active yeast cells left. 

Transferring your beer to a secondary fermenter and allowing it to condition will allow the surviving yeast to convert the more complex sugars. 

This improves the quality of your beer by boosting clarity, smoothing out the flavor profile, and lowering the danger of infection and off-tasting flavors.

Brewers often choose to “dry hop” their beer during the secondary fermentation stage. 

Dry hopping is the method of adding bitterness, flavor, and aroma to your beer by physically infusing it with hops. 

Dry hopping is style-dependent (particularly so for IPAs and other hoppy beers). 

Secondary fermentation is an appropriate time to dry hop because the intense fermentation and rapid CO2 release have already occurred, enabling the hops’ oil and aroma to settle in gently.

The secondary fermentation phase should take at least one week to finish, although you can certainly extend it if necessary.

Should You Always Go Through Secondary Fermentation? 

Nope. Secondary fermentation isn’t required, although it has a lot of advantages when making beer at home. It’s at this point that the beer can clear up even more and become more refined.

However, if done incorrectly, it can bring infection and other elements that can negatively impact your brew. 

Secondary fermentation, when done correctly, produces a product that is both better-looking and better-tasting. Let the beer ferment for 2-3 weeks in the primary fermenter if you don’t want to do a secondary fermentation.

Step 9: Carbonation and Packaging 

beer brewing steps - Carbonation and Packaging 

After fermentation, the beer must be kegged or bottled and carbonated, either naturally or artificially. 

Forced carbonation is the process of injecting CO2 into a container at high pressure, forcing it to soak into the beer. 

Forced carbonation is used by most breweries since it is a much speedier procedure that results in more clarity in bottled beer.

Krausening is the traditional technique for introducing carbon dioxide during the fermentation process. 

Bottle conditioning, or adding a little amount of sugar and yeast to the bottle at the time of bottling, is another way to get carbonation. 

When a cask-conditioned real ale is first introduced to the cask, sugar, yeast, and hops are added to carbonate the beer.

Beer Brewing FAQs

How can you tell if a beer is infected? 

If things seem funky to you, something is most likely wrong. However, if this is your first batch, don’t panic just yet. 

Simply complete the directions that come with your beer making kit and then taste the resulting beer. Is it still drinkable? 

If that’s the case, you’re in good condition. If this is not the case, something went wrong. It could be an infection or any number of other problems.

Even if you do find a possible infection, use it as a learning opportunity; your next batch will undoubtedly be far better.

Do you sometimes need to rehydrate dry yeast? 

Certainly not. You may brew beer by simply sprinkling yeast on the wort. It works perfectly and is quite simple. 

Is this, however, the optimum method for pitching dry yeast? That is a point of contention. 

Before pitching, many experts agree that yeast should be rehydrated in a little amount of water. 

Their logic is sound, but if in doubt, read the yeast packet instructions or go to the manufacturer’s website for more information.

Why is my airlock not bubbling?

This is by far the most common issue that home brewers encounter. Fermenters don’t always seal effectively, and if they don’t, the air lock won’t bubble, and aging seals frequently cause leaks. 

Take a hydrometer reading or hunt for visible clues of what’s going on to assess the situation appropriately. 

If the brew is still fermenting, close it as tightly as possible and replace the lid, seal, and grommet before brewing again. If it’s done, bottle it right away. Don’t toss it out; it might not be bad at all.  

The airlock’s purpose is to keep insects and air out while allowing CO2 to escape; it is not intended to serve as a guide to the fermentation process.

It’s been a while. Why isn’t my beer carbonating? 

Carbonation is achieved by giving the yeast a modest amount of extra priming sugar to eat when bottling beer. 

The yeast will devour the sugar and produce CO2 after capping. But because the bottle is sealed, the carbonation will have nowhere to go but into the beer’s solution. 

The yeast must have optimum conditions in order to accomplish their function, including a temperature range that is warm enough for them to work. This is normally around 70 degrees Fahrenheit. 

During this phase, if the beer is placed in a chilly basement or refrigerator, the yeast will either not carbonate the beer or will do so extremely slowly. 

Place the bottles in a warmer environment and wait a bit more. Only in exceptional circumstances will you need to take further steps to carbonate your beer.
