The Best Home Coffee Roasters
It’s one of those annoying coffee cliches, but it’s true: Freshly roasted coffee is one of the most delicious things in the world.
In spite of what many people think, coffee has a rather short shelf life.
It starts incredible, and within two weeks much of that magic is gone.
It’s similar to baking bread: The difference between fresh and old is dramatic.
If you never want to drink stale coffee again, there’s only one way to be entirely sure that you’re getting the fresh stuff: Roast coffee at home.
Roasting coffee is not rocket science, but I wouldn’t say that it’s child’s play either.
Treat it like a hobby with a bit of a learning curve, and before long you’ll be rewarded with some pretty magnificent home-roasted beans.
My top pick:
It’s a genuine drum roaster, so it’s a suitable device to learn the roastmaster craft on.
With this machine, you’ll be able to roast a week’s supply of coffee in about ten minutes.
I have had mine for two years, and it’s been taking a lot of heat and abuse without any hiccups whatsoever.

How to find the best home coffee roaster
Roasting in its purest form is all about transferring heat to the green coffee bean. Within minutes the green coffee turns from dense and undrinkable into the brown, porous coffee bean that you know.
However, only looking at coffee roasting this way is too simple: Coffee roasting is a craft, and getting a good result is all about applying just the right amount of heat. That is why many home coffee roasters quickly graduate from typical beginner methods such as oven and popcorn roasters to dedicated tools.
There are three common types of home coffee bean roasters available:
- Hot Air: These devices are radically upgraded popcorn machines that roast the beans by applying hot air. The hot air is sent out of vents that simultaneously spin the coffee beans around. This constant spinning ensures that the coffee beans roast evenly.
Hot air roasters tend to roast the beans rather quickly which means that a lot of delicate aromas are developed, while body and caramelization tend to be lower than in drum roasters.This kind of home roasting machine typically has a lower capacity than drum roasters.
- Drum coffee roaster: This kind of coffee roasting machine works by spinning the beans around inside a heated metal drum. This is the most popular professional roaster since one can roast large quantities while still getting even and tasty results.For a home coffee roaster who dreams of becoming professional this kind of device is ideal because it prepares you for the real job. Home drum roasters come in all sizes, from 200 grams to several kilos.
- Conduction home roasters: This category covers the many cheap but not very useful coffee roasters that somehow roast beans by applying direct heat and either manual or mechanical agitation.You can probably get a decent result this way but to be honest, it’s never going to be much better than just using your oven, since you’ll not be able to modulate and stretch of the different phases of the roast.
Benefits of a small batch coffee roaster
One of the most important things to consider when shopping for a small coffee roaster is the capacity.
If you drink much coffee on a daily basis, you don’t want a machine with a low capacity.
I used to roast coffee in a popcorn machine, but with a capacity of around 100 grams/4 oz, it quickly grows cumbersome.
100 grams of coffee will turn into 85 grams of roasted coffee, which you’ll probably be able to drink in a day or two.
Many coffee roasters work better when not loaded at full capacity, so you want to have a bit of wiggle room.
Even though it might only take 10 minutes to finish a roast from load to drop, all the small details in your workflow will add extra time:
- Measuring batch size
- Cooling down beans
- Updating your roast log
For those reasons, I wouldn’t recommend a roaster with less than a 300 gram capacity. While it’s fun to roast, you also want to see (and drink) the fruit of your labor.
The more control you have over temperature and airflow, the more you’ll be able to tweak your roast profiles. For those reasons, I’d highly encourage you to get a device that has a digital thermometer and a dedicated temperature control.
If you don’t have any of these tools at your disposal, you’re going to be less consistent. Even though it is possible to roast purely from sensorial cues, it’s not recommended. To learn and adapt your roasting style you need a bit of data.

Kaldi Wide drum coffee roaster
The Kaldi Wide is a quality home drum roaster produced by the tiny Korean company, Kaldi. I have owned this model for almost two years, and it has stood up to two-three back to back batches virtually every week in that period.
In some aspects, you get a professional machine in a miniature version. There’s a thermometer and a trier, so you can monitor bean temperature and check the color as you go along.
The capacity is quite good for a home roaster (you can get away with up to 330 grams), and the machine is put together exceptionally well. I have dropped mine on the floor on one occasion, and it survived with just minor scratches.
The Kaldi Wide has started to become a cult favorite among home roasters since it offers the best combination of value, sturdiness, and hands-on roasting experience.
Keep in mind that you need a separate gas burner for this roaster – the heat source is not included.See more reviews
Gene Cafe CBR-101 H
The Gene roaster is one of the most popular home models, and it’s easy to understand why. It blends a bunch of cool technology with convenience. If you want a workhorse for your home, this is a good bet since it’s almost smokeless, easy to clean, and also has a chaff collector. With a capacity of 250 grams it suitable for many coffee geeks.
It has a slightly unusual off-axis drum. The reason for this design is to get more even roasts. According to the reviews, it seems to work very well. Visually, you can follow along in the roasts very well both judging bean color and temperature, but sound-wise the device is a bit loud which might obscure the first crack; which for a roastmaster is seriously annoying.
Some customers also raise concerns about the longevity of this roasting machine.See more reviews
The Fresh Roast is a brilliant first roaster for someone who wants to try roasting some beans without getting too committed. It’s budget-friendly and easy to use since you can see the beans in the glass container while they are changing color.
The roaster also has a chaff collector which is fantastic if you’re roasting indoor at home (trust me on this one). There’s also a cooling cycle built in.
The main problem with this roaster is that the capacity is low at around 90 grams, even for just a single coffee addict that is a bit on the small side.See more reviews
Ceramic home coffee bean roaster
This is an incredibly simple small batch coffee roaster for somebody who wants to try roasting at home without any real illusions of producing something outstanding. It’s easy to pour the beans in and out. Aside from that, the main point of this thing is that it’s cheap.
Some skilled people with powerful hands might be able to get an even roast of out of this, but the chances are that your beans are going to get burnt. If you have an oven, I will use that over this apparatus.See more reviewsNo products found.
Behmor 1600 plus
The Behmor is one of the grand old men of home coffee roasting. There are some GREAT things to say about it but also some more negative ones.
It has an enormous capacity for a home roasting device with up to 1 pound per batch, which is the most appealing thing about it. With this model, you’ll be self-reliant when it comes to freshly roasted beans!
However, many customers complain about the design — notably, the safety feature where the roaster shuts off in the middle of the action. If you don’t carefully keep an eye on this, your whole batch might be ruined.
Also, some reviewers complain that it’s hard to get consistent results.
The last con for some people will be that this device isn’t suitable for darker roasts.See more reviews
