How to brew beer

So you’ve decided to make your own beer at home. Congratulations! You’re about to engage in a wondrous and rewarding task almost as old as humanity itself. But there’s no reason to be intimidated. Although people have been brewing beer for millennia, the basic process has remained much the same through the ages. This article will discuss what the basics of how to brew beer, home brewing equipment you need to get started as well as walk you through the basic steps of how to brew a Texas Kolsch. It’s time, as homebrewing godfather Charlie Papazian says, to “Relax, don’t worry, have a homebrew.”

How to Brew Beer

First off, homebrewing can be divided into two types: all grain brewing and extract brewing. Beer is made using the sugars from malted (partially germinated) grains. In all grain brewing, the homebrewer via a series of steps extracts these sugars from milled grains him or herself. In extract brewing, the homebrewer uses ready-made malt extract, skipping the sugar extraction process entirely as it has already been done.

Extract brewing is a good starting point for most new homebrewers because the process requires minimal beer making equipment and procedures while still producing quality beer, and it’s the type of home brewing we’ll focus on or the rest of this article.

Equipment You Need to Make Your Own Beer

You may know someone who has converted his or her entire basement or garage into what practically looks like a professional brewery, full of shiny fermentation tanks and kegs, welded pipework, washing stations, and fridges with tap handles always pouring out beautiful heady beer. But rest assured there is no need to invest a fortune to get started making your own beer. The easiest way to go is to just buy a beer making kit. You can always add fancier brewing gadgets and fermentation equipment after you’ve brewed for a while and decided it’s something you love (which you will, of course).

What's in a Beer Making Kit

You will also need a cooking thermometer and a 3-5 gallon stock pot, which is available as an add-on if you don’t already have one.

Ingredients of Beer Making

Now that you have the equipment taken care of, let’s go over the main ingredients of beer. There are only four: hops, grains (and/or malt extract), yeast, and water. We’ll look at each one individually.

Hops are the flowers (cones, really) of the plant Humulus lupulus. Hop cones from female plants are used in brewing and contain the alpha acids that determine that particular hop’s bitterness. The higher the alpha acid percentage, the more bitterness that hop will contribute to your boil. Typical boils last 60 or more minutes because the hops’ alpha resins are not readily soluble in water and must be boiled for at least an hour to release their bitterness.


Important note: The acid percentage of hops varies from year to year, hop variety to hop variety, and region to region, so it’s important to keep good records of your brewing so that you can duplicate your successful brews. Refer to the package your hops come in for the most accurate alpha acid percentage.

In addition to being used in the boil to add bitterness to your finished beer, hops are also added toward the end of the boil to impart aroma and fragrance. This is important because much of what we perceive as taste comes through our sense of smell. Hops used in the boil are called bittering (or boiling) hops, while hops added at the end are known as aromatic (or finishing) hops.

Even if you are brewing with malt extract, using a small amount of what are called “specialty grains” can help give your beer added flavor, aroma, color, and body. Buying your grains from a reputable homebrew shop like Austin Homebrew Supply will help ensure that you’re getting grains that are fresh and have been stored properly.


To be used in making beer, grains must first be milled (or crushed). You can do this at home if you have a grain mill or other method capable of crushing the grains finely, or you can do it (or have it done) at the homebrew shop. Crushed grains should be used as soon as possible, while uncrushed grains will store well for up to four months.

Malt Extracts

Using malt extracts is a convenient way of making your own beer and can make the process more enjoyable for new brewers. Whether you have just a few or more than a hundred batches under your belt, extracts can produce exceptional beers. The quality of extracts has improved greatly over the years and can be depended on to provide consistent results.

Malt extract is available in liquid malt extract (LME) or dry malt extract (DME) form. But be careful: which form you use affects how much you need for a given recipe. You can use a simple calculation to help determine what kind of original gravity – a measure of the fermentable sugars in your unfermented beer (wort) – you can expect from LME vs. DME. Here is the rule of thumb:

  • 1 lb LME will produce a 1.044 original gravity when dissolved in 1 gallon of water.
  • 1 lb DME will produce a 1.037 original gravity when dissolved in 1 gallon of water.

You can use these calculations to determine how many pounds of LME or DME you need to achieve a known original gravity if you aren’t using a pre-measured beer recipe kit.

Beer was brewed for millennia before brewers understood the role yeast played in fermentation. Today, you may have heard the common saying, “Brewers make wort; yeast makes beer.” In brewing, yeast, which is a single-celled fungus, consumes the malt sugars and produces alcohol and CO2.


Like malt extract, brewer’s yeast comes in liquid brewing yeast or dry brewing yeast form. It used to be that dry beer yeast was looked down upon as being of poor quality and not adding much to the beer, but these days there are many varieties of dry yeast made specifically for different beer types.

There are advantages and disadvantages to using either dry yeast or liquid yeast. Dry yeast has a long shelf life and requires minimal preparation to use. Liquid yeast comes in vastly more varieties than dry yeast but has a shorter shelf life and requires more careful handling. Either way, you can achieve the quality beer you are looking for.


The quality of the water you brew with is important because beer is more than 90 percent water. Basically, water used for making beer needs to be clean and free of odors (a typical example of odor is chlorine). Other factors to consider with your water include its pH and “hardness” (minerality). Good brewing water should be moderately hard and have low to moderate alkalinity. There are ways to adjust your water chemistry, if necessary, to get it where you want it; however, many homebrewers make perfectly good beer with “as-is” tap water.

Making Your Beer

We’ve gone over the brewing equipment and the main ingredients you need to homebrew.

AHS Texas Kolsch Beer Making Kit tile

Now let’s take a look at a classic Austin Homebrew Supply extract beer recipe kit the Texas Kolsch.

Texas Kolsch Specs:

  • Yield: 5 gallons
  • Original gravity: 1.054
  • Final gravity: 1.012
  • Alcohol by volume: 5.2%
  • Specialty grains: Carapils
  • Hops: Crystal

Texas Kolsch Recipe kit includes: Liquid malt, specialty grains, a grain bag, and hops.

This recipe is very popular here at Austin Homebrew Supply. At 5.2% ABV, the alcohol content does not overpower the maltiness. This particular recipe is perfect for beginners and well balanced for the experienced brewer as well.

Now let’s go through the steps to make your beer.

Brewing Procedure:

Always read all the instructions before you begin brewing, so you can be sure you have everything you need on hand (equipment, ingredients) and that you fully understand the procedure.

Clean and Sanitize

Thoroughly clean and sanitize all of your brewing equipment.

Steep Your Grains

Start by heating 2 gallons of water in your brew pot to 155°F. Add the (crushed) specialty grains to the grain bag:

    Tie a knot at one end of the grain bag, leaving room for the grains to be loose in the bag. Place the grain bag in the water. Steep your grains at this temperature for 25 minutes. Remove the grain bag from the pot. Do not squeeze the bag; just let the liquid drain from the bag into the pot. You now officially have “wort” – unfermented beer. But there are several other steps to fully prepare your wort for fermentation.

    Begin the Boil

    Add one gallon of water and bring the wort to a rolling boil, being careful to avoid a boil-over. Once you’ve achieved a boil, remove the brew pot from the heat source.

    Now add:
    • 5 lbs Pale LME
    • 2 lbs wheat DME

    Stir the wort until the malt extract has completely dissolved. Any undissolved extract allowed to sit on the bottom of the pot will burn, so make sure you’ve stirred thoroughly before returning the wort to a rolling boil.  Now add the 5 HBU Pack to boil for 60 minutes.

    Next, add Aromatic Hops

    Let your wort boil for 55 minutes, then add:

    These are your aromatic (or finishing) hops. Because you are boiling them for only 15 minutes, they add minimal bitterness, but contribute their aroma and fragrance to the finished beer.

    Cool the Wort

    Following the 60-minute boil, you’ll need to cool your wort down to below 80°F as quickly as possible. There are many ways to do this, but we recommend using a wort chiller.

    If you haven’t already, now is a good time to sanitize your fermentation equipment, i.e., the “Ale Pail,” airlock, hose, and hydrometer. Your wort at this point is a big feast for microbes, and you don’t want any uninvited guests showing up to the dinner party. Anything that may come into contact with the wort should be sanitary.

    Transfer the Wort to the Fermenter

    Siphon the cooled wort into your primary fermentation vessel (your “Ale Pail” if you’re using the basic homebrewing equipment kit), then top it off with enough cold water so that you have 5.25 gallons. You’ll also want to aerate the wort, either by using a diffusion stone or simply by rocking the fermenter back and forth once the lid is in place.

    Determine Your Original Gravity

    Now is when you want to use your hydrometer to measure the wort’s original gravity (OG), which basically indicates a number of fermentable sugars present. You’ll want to record the number as you will use it later, along with your final gravity reading, to calculate your beer’s alcohol by volume (ABV).

    Pitch the Yeast

    Now it’s time to add, or “pitch,” your yeast into the wort. During fermentation, the yeast will consume the malt sugars and produce alcohol and CO2. The wort should be cooled to around 78°F before you pitch your yeast, but follow the procedures outlined on the yeast package. We suggest using one of the following yeasts for the Texas Kolsch:

    White Labs German Ale/Kolsch P029.

    Wyeast Kolsch Ale 2565

    Fermentis SafeBrew S33.

    After you’ve pitched the yeast, seal the fermenter tightly, attach the sanitized airlock and stopper, and fill the airlock with water.

    Let the Wort Ferment

    Put the fermenter in an out-of-the-way, temperature-stable place. You should see activity within 24-48 hours as CO2 begins to escape the airlock. It will take from one to two weeks for the fermentation to complete, during which time you should do nothing to disturb the process.

    Some brewers include a secondary fermentation step after about a week. It involves siphoning the beer into a secondary fermenter, such as a glass carboy, and allowing it to condition for another week or two. This step is optional (at least for some beers), but the advantages include allowing the beer to clear more, resulting in less sediment once you’ve kegged or bottled it.

    Determine Your Final Gravity and Calculate ABV

    Use your hydrometer to take a reading of the beer’s final gravity (FG). You can calculate the beer’s approximate ABV using the following formula:

    ABV = (OG - FG) x 131.25

    So using our targets for the Texas Kolsch, we’d get:

    (1.054-1.012) x 131.25 = 5.51% ABV

    Note that this calculation provides only an approximation of the beer’s ABV, but it is the simplest method and is generally “good enough” for homebrewing.

    Keg or Bottle Your Beer

    Siphon the finished beer into the bottling bucket. If the recipe calls for any bottling additives (such as priming sugar) to be added to the bottling bucket, add them now.

    At this point, follow kegging or bottling procedures.

    That’s all there is to making your own beer. After allowing the beer to condition, it’s time to share it with friends and family and brag about how you made it yourself. Welcome to homebrewing!

    Now you know the basic process for brewing your own beer at home. As you gain experience and confidence, you can work in more wrinkles, such as using gypsum to harden your brewing water (if necessary) or adding Irish moss to your boil to help with beer clarity.
