Why Should You Choose Home Coffee Roasting?

Many would wonder why would anyone go through all the trouble of roasting coffee at home when it’s easy to buy roasted coffee at a local coffee shop and save time?

Look, when you start roasting coffee beans at home, you learn a lot of things. For instance, you will learn more about different coffee, you will also roast coffee according to your preferences. In the end, you will enjoy the freshness of home-roasted coffee.

Although many people would start with a popcorn maker, we wouldn’t recommend you to use it for your home coffee roasting.

If you are really looking to brew barista-like coffee, you should choose the best machine to roast your own coffee beans at home.

Why Shouldn’t You Choose A Popcorn Maker?

Typically, a popcorn popper roasts coffee beans by pushing hot air through a pile of tiny kernels.

This is exactly how coffee roasting is founded. But here our concern with a popcorn maker is that it doesn’t roast coffee beans consistently (some will be over roasted while others will be under-roasted…and when it comes to brewing a fresh cup of coffee, consistency is everything.

Another thing why we wouldn’t advise you to roast coffee beans with a popcorn maker is that the machine allows you to roast a small batch at a time.

There are plenty of different coffee roasters out there. So, before you rush out and buy the first machine you see, here are some useful tips to help you choose the right home coffee roaster for home coffee roasting.

Consider The Size

Chances are that before you purchased your coffee maker, you considered the amount of coffee you are going to brew based on the number of people who are going to drink the coffee.

When buying a coffee roaster, you also need to consider the amount of coffee beans you are going to roast at home.

Generally, roasters come in different sizes.

For instance, air roasters can only roast small batches of coffee while drum roasters can roast large amounts due to their large roasting chambers.

Well, if you intend to roast small amounts of coffee of different types weekly, you may consider buying a smaller air roaster.

If you want to roast coffee beans you will use the whole week, a drum coffee roaster would be the best option for you.

In short, before choosing a home coffee roaster, think about the amount of coffee you will consume every week and the frequency of roasting.

Understand the Types of Bean Coffee Roasters

Typically, there are two types of home coffee roasters namely air roasters and drum roasters.

Air Coffee Roasters

Air coffee roasters resemble popcorn makers where hot air is blown on coffee beans that are spread on a bed. An air roaster will take around 8 to 12 minutes to roast coffee beans. Sometimes air roasting may result in over-roasting or under-roasting of beans and cannot roast large amounts of beans at once. These types of roasters are suitable for home use. But if you are planning to roast large batches of beans at once, this type would not be suitable for you.

Drum Coffee Roasters

Drum roasters; on the other hand, involve hot air flowing around rotating cylinders to heat the coffee beans. This is meant to achieve even roasting.

Drum roasters take around 16 minutes to roast coffee beans.

The good thing about drum roasters albeit being slow can roast large batches of coffee beans at once. These types of coffee roasters can make full-bodied and strong coffee with darker beans. They are also suitable for use at coffee shops.

Opt for a Roaster with a Cooling Feature

As a rule, once the coffee has been roasted fully, the beans need to cool down fast otherwise, the heat generated in the chamber will continue roasting the beans.

For this reason, it’s important to choose a roaster with a cooling feature.

Most of the latest home coffee roasters will blow cool air through the roasting chamber after roasting beans to the desired level.

Other high-end roasters come with an external tray where the beans are dumped onto and cooled quickly. This prevents over-roasting of the beans.

Ease Of Use

The trouble that one has to go through to roast coffee beans perfectly is perhaps why most coffee lovers prefer to buy roasted beans at a local coffee shop.

Ideally, if you have little or no experience with home coffee roasting then you need to choose a roaster machine that’s easy to control the flame and airflow.

Some coffee roasters are pre-programmed. You just need to select your roasting level and the equipment will do the roasting for you.

Others have inbuilt motors that turn the beans for even roasting. This helps to prevent overcooking or undercooking the beans.

Ideally, you need a home coffee roaster that’s easy to use and allows you more control over the process.


While you will be purchasing a home coffee roaster for roasting beans, these machines aren’t only meant for coffee beans alone.

If you will need to roast popcorn, seeds, or nuts, you need to choose a versatile coffee roaster machine.

Multipurpose coffee roasters are suitable for roasters who love fresh ingredients.

A coffee roaster that does more than one job will also give you value for your money.

Therefore, the next time you are choosing home coffee roasting equipment, consider whether you want one that can handle more than one job or not.

Cost of the Home Coffee Roaster

Usually, before you hit the road in search of a coffee roaster, you need to decide how much you want to spend on the machine.

Once you set your budget, it would be easier to choose a roaster that’s either below or within your budget.

Remember, coffee roasters just as they come in different sizes, they also come with different price tags.

But even if you don’t have enough money to buy a roaster you can always lease one instead of buying it.

As a rule, you shouldn’t choose a cheap roaster and even though good quality roasters are expensive, they tend to last longer and can offer you good service.
