Before thinking about homebrewing, you need to understand the two main brewing processes, extract brewing and all-grain brewing. The decision you make between the two will greatly affect your brewing process and final brew. Each of these brewing processes has reasons, advantages and disadvantages.
While every brewer may have strong opinions about each of these methods, neither method is the "correct" or "perfect" method of brewing. If you understand brewing and learn to brew with these ingredients, you can get a high-quality and delicious beer either way. Brewing is a science, and while you may need to follow some rules, there is also a lot of room for experimentation and methodological variations.
What is Extract Brewing?
Beginning home brewers often use this process because it doesn't require you to grind the grain yourself. Grain mills are often an expensive investment for someone just starting out, especially if you're just trying out the hobby. Instead of grinding the grain yourself, you mix concentrated malt extract and hops to make wort, the sweetened liquid extracted from barley that is the base of beer.
Extract brewing saves you the time you spend grinding and mashing grains to make malt extract. This step can be very technical and advanced for beginners, which is why many beginners start with extractive brewing. Brewing with extracts doesn't lose the complexity of the beer. When you first start brewing, making your own extract through whole grain brewing is a technical and more difficult process, meaning the extract you get may not be as good as pre-made extracts.
The downside of extract brewing is that you are limited by the malt extract and you have less control over the resulting beer. For starters, this is a great way to get into the very complex world of beer brewing, as you can tweak and use three main factors to customize your beer - alcohol content, hops, and color of your beer. After you've mastered these basics, you can try brewing with whole grains, which allows for an almost endless number of ways to manipulate and change the character of your beer.

What is malt extract?
Malt extract is the concentrated sugar extracted from barley malt during the mashing process and can be found in liquid or powder form. Malt extract is made by grinding grains and soaking them in hot water to hydrate the barley, activate maltase enzymes, and extract the grain's fermentable sugars.
When you use malt extract, you can skip the grinding and mashing stages of the brewing process, saving you a lot of time and extra equipment.
Types of Malt Extract
The two types of Malt Extract, dry and liquid, have different water and sugar contents. This means they are not interchangeable in recipes.
Dry Malt Extract (DME)
This is a powdered form of Malt Extract, in which almost all the water has been removed through an evaporation process.
Longer shelf life
Cost-effective - you need to less of it to brew
More temperature tolerant and stable
Easier to measure and achieve accuracy
Reacts poorly to humidity
A smaller variety available
Has a tendency to clump
Messy to deal with because of its super fine powder texture
Liquid Malt Extract (LME)
The liquid version of malt typically contains about 20% water and 80% sugars and unfermentable solids.
Has a better and richer flavor when liquid is fresh
A broader variety available
Convenient packaging for storage and transport
Sticky consistency makes it difficult to pour and measure accurately
Hard to store again once opened
Susceptible to aging, an older liquid will not provide the best flavors
Constrained to the size of liquid malt containers for brewing
Hopped vs. Unhopped Malt Extracts
While most malt extracts come unhopped, which means that during the boiling process the brewer will add the Malt Extract with the desired amount of hops to create the wort. With hopped or Pre-Hopped Malt Extract, the hops are already combined saving a step in the process but it means your brew isn't as customizable and you have less control over your resulting beer.
Hopped Malt Extracts are a significant time-saver because hops have already been processed with the malt and they are ready to be fermented. With some hopped Malt Extracts, the brewer can skin the boiling phase of the brewing process, which can be a bit technical for a beginner. It is hotly debated whether Hopped Malt Extracts need to be boiled, we recommend boiling your Malt Extract for sanitation purposes but some Malt Extract makers may recommend that you do not boil your extract.
What is All-Grain Brewing?
This brewing process is what you would traditionally associate with brewing beer and it is a more time-consuming and process-heavy method. This brewing process involves starting from the very beginning with the raw material, the grains, and ending with a delicious fermented beverage, known as beer.
The major difference between All-Grain Brewing and Extract Brewing is the beginning stages of the brewing process, which can be skipped when using Extract Brewing but are required in All-Grain Brewing. In order to catch up to the stage that Extract Brewing starts at, the brewer needs to mill the grains, mash them, and boil them with the hops to create wort for fermenting.
The advantage of milling your own grain is that it will give you the freshest and best flavor. It also gives you full control over the flavors in your resulting beer. Additionally, grains store very well for long periods of time and in the long run, it is more cost-efficient. Milling your own grains will take time and energy to do, whether you decide to hand-crank all your grains or use a motorize method. You can learn how to mill your own grains in our guide here.
It is important to properly mill your grains will a grain mill because grinding your grains in another device like a blender will result in paste in your mash tun, which you don't want. Another option is purchasing crushed grains, which have been already milled for your convenience. If properly stored in an airtight container you will not lose the flavors of the grain but ideally, for the best flavor, you will want to mill your own grain.
After you mill your grains, you will need to mash them to pull out the starchy sugars that are used as the base of your beer for fermenting. This requires steeping your grains in hot water at a specific temperature depending on the beer you're brewing. The temperature you mash your grains in is crucial because it creates the sugars that your yeast will be eating, therefore affecting your resulting beer's flavor profile. This technical and time-consuming step is why some brewers choose to brew with Malt Extracts.
After your grains have been mashed, there is the lautering process, which is the removal of the grains from the liquid. This step is necessary but also a messy step in the All-Grain Brewing process. There is also the sparging process, which requires rinsing the grain bed again and steeping the grains to pull out any remaining sugars.
Finally, to finish your wort, you need to carefully boil your wort to a specified temperature for your beer type and add in the hops. This is a stage you will still have to do if you are Extract brewing with unhopped extract but if you use a pre-hopped version, you will be skipping this step of the process.
With All-Grain Brewing, you can manipulate so many different factors that will affect your final result. There are virtually endless possibilities and combination of ingredients that you can use to customize your beer, however, this often takes a lot of skill to create a quality beer.
Additionally, All-Grain Brewing can require up to three times the amount of equipment that Extract Brewing requires, depending on your brewing style. However, it allows you to play with a variety of factors that will affect the taste of the beer and build complexity. There are many different methods for All-Grain Brewing that we will go into in a different article.
Which brewing method is right for me?
If you are a beginning brewer, we highly recommend starting with Extract Brewing because it requires less equipment, ingredients, and skill. Many people even start brewing with Brewing Equipment Kits that include everything you need to brew from equipment to ingredients and they often include step-by-step instructions to help you through the process. Since it skips many time-consuming steps, Extract Brewing is also ideal for those who don't have a lot of time to brew but still enjoy homebrewing.
As you develop more skills and you become a more dedicated brewer, you will want to use Extract Homebrewing Equipment to do your extract brewing, these equipment starter kits have everything you need to brew except for the ingredients, which for more intermediate brewers, there are homebrew ingredients kits available that include all the ingredients to brew a variety of beers.
As you grow in skill and confidence, you will want to move away from ingredient kits and move into choosing your own ingredients. We offer a wide variety of dry malt, liquid malt, hops, yeast, and other brewing ingredients to choose from for extract homebrew.
Finally, when you're ready to venture into All-Grain Brewing, you will be able to use some of the same equipment but depending on your All-Grain brewing method, you may find yourself need a significant amount of additional equipment, including a grain mill. You can find Homebrewing Equipment Kits here but you can also pick your individual Boiling and Mashing Equipment here and Fermentation Equipment here. For those who are looking for a means to All-Grain Brew with minimal equipment or those who have space limitations in your home, there are Brew Systems that allow you to do the mashing and boiling process in one vessel.
