Best Home Coffee Roaster 2024

Kaldi Coffee Roaster

-Best Coffee Roaster-

Kaldi Home Coffee Roaster

Type: Drum Roaster | Capacity: 250 grams (200g recommended)

The Kaldi home coffee roaster is a Korean-made drum roaster. This is a serious machine that delivers on looks, features, and build quality. While the Kaldi roaster requires a significant upfront investment its performance makes it worthwhile, particularly if you are wanting to get into coffee roasting in earnest.

The Kaldi is a fully motorized drum roaster with a stirring drum that holds up to 250 grams of beans. To roast coffee beans you place the roaster on top of a gas burner and, once it has warmed up, pour the coffee beans through a funnel at the top. There is a temperature probe inserted into the rotating beans so you can gauge the bean temperature. There is also a sampler for you to see what stage the beans are at. The machine is quiet when in use allowing you to hear the first and second cracks. While there are few bells and whistles, you can control the temperature (via the gas stove) and the roast time.

The downsides of the machine are that it doesn’t come with any smoke suppression technology, so needs to be used in a well-ventilated area. It also has a steep learning curve, which in addition to the high price tag, means it is not a very good option for beginners. Overall the Kaldi roaster is a high-quality machine that is a workhorse with few extra bells and whistles. It produces even and consistent roasts and is ideal for the hipster wanting to master the art of roasting. Kaldi also have a mini roaster which is smaller in size and slightly cheaper.


  • Large capacity, up to 250 grams of beans
  • Quiet machine, able to hear first and second cracks
  • Sampler to see what stage beans are at
  • Well built
  • Produces even and consistent roasts


  • Expensive
  • Separate gas burner required
  • Poor chaff collection, can be messy to clean up
  • Machine gets very hot
  • No smoke suppression system

Fresh Roast

-Best Roaster For Beginners-

Fresh Roast Coffee Roaster

Type: Air Roaster | Capacity: 120 grams

The Fresh Roast is an air roaster that is fun and simple to use. A knob on the front of the machine allows you to select from nine different temperature settings, adjust the fan speed, and select the roast time before hitting start. The glass roasting chamber, combined with a real-time temperature reader, helps you keep track of the roast’s progress. The Fresh Roast has a quick roast time taking anywhere between 6-10 minutes depending on the origin and roast level you are aiming for.

The machine itself is very compact and quiet when in use, however, due to the smell omitted when roasting it is recommended to use the machine outside or in a well-ventilated area. The only drawback is that it only has a small 120-gram capacity, so not ideal if you are wanting to roast a larger batch of beans. Overall the Fresh Roast is the ideal machine for beginners. It is easy to use, affordable, and highly reviewed.


  • Affordable
  • Compact size
  • Easy to use and clean
  • Cooling cycle and chaff collection systems
  • Good visibility of beans during roasting


  • Only roasts a small amount of beans
  • Some report the fan is not strong enough to move the beans adequately at the beginning of roasting- may be required to gently tip the unit to the side to encourage movement
  • No smoke reduction systems

Nuvo Coffee Roaster

-Best Budget Coffee Roaster-

Nuvo Coffee Bean Roaster

Type: Manual | Capacity: 70 grams

The Nuvo coffee roaster is another Korean-made hand roaster, with a very basic design. This roaster is completely manual with no timers, temperature settings or cool down features. To roast you simply put your green coffee beans in the chamber and hold the roaster over a gas or electric stovetop (but not induction). Once it heats up you shake it, listening for the first crack and when the beans reach your desired roast level you empty them through the hollow handle. A medium roast generally takes around 10-12 minutes.

The Nuvo has a compact design and a correspondingly small 70 gram capacity. The one drawback of the design is that the handle can get hot, so it is a wise idea to wear gloves while roasting. All-in-all the Nuvo is a simple and affordable roaster and would be a great step up from using a frypan or popcorn maker. If you are a beginner, looking for an entry level home coffee roaster the Nuvo is worth considering.


  • Affordable
  • Roasts small batches well
  • No noise
  • Portable, good for camping
  • Easy to clean- just wipe out with a cloth once cool


  • Small capacity
  • Hot beans can fly out of handle causing a potential hazard

Mifxin Coffee Roaster

-Best For Large Batches-

Type: Electric | Capacity: 800 grams

If you are looking for a large-capacity roaster the Mifxin is a great option. This roaster holds a whopping 800 grams. And not only is it simple to use, but it also has an affordable price tag.  

Resembling a slow cooker, the Mifxin roaster has a straightforward design. The inside is lined with a non-stick coating making it easy to clean. Inside there are rotating arms that stir the beans during roasting. A dial on the front allows you to adjust the temperature from 100 to 240 C giving access to the full range of roast levels from blonde to Italian. And finally, there is a transparent glass lid on top allowing you to keep a close eye on the beans during roasting. A roast usually takes around 20-30 minutes.

The simple design does have some limitations. Some users report that the arms do not do the best job of stirring if there are either too few or too many beans. Also, there is no chaff collector which can make it messy. All things considered, the Mifxin is a great value roaster and a sound investment for coffee lovers.


  • Large capacity
  • Affordable price
  • Adjustable temperature


  • No chaff collector

Dyvee Gas Roaster

-Best Design-

Type: Drum Roaster | Capacity: 400 grams (200-300g recommended)

The Dyvee Gas Roaster is an easy choice if you already have a gas stove at home. This drum roaster has a stunning design with a stainless steel frame, a Quartz glass drum, and a wooden handle for an elegant finish. The transparent glass drum is the most striking feature allowing you to watch the whole roasting process. 

To operate the roaster you simply fill the drum with green coffee beans, place the roaster over a gas burner, and then turn it on. The drum automatically rotates, stirring the beans. A manual thermometer inserted into the drum allows you to gauge the temperature and adjust the gas stove accordingly. The Dyvee can roast up to 400 grams of beans at a time, although 200-300 grams is recommended. Roasting takes anywhere from 20-60 minutes depending on the number of beans and roast level, which does make it one of the slower coffee roasters on this list. 

While the Dyvee is a stunning roaster, it is not perfect. It doesn’t have any smoke suppression system so outside use is recommended. There is also no chaff collector which can make it messy. In addition, the roaster requires a separate gas burner. 


  • Stunning design
  • Transparent drum allows you to see beans while roasting
  • Roast up to 400 grams at a time


  • Requires separate gas burner
  • No features like smoke suppression or chaff collector
  • Slow to roast

Hottop Coffee Roaster

-Best Splurge-

Hottop Coffee Roaster

Type: Drum Roaster | Capacity: 300 grams (250g recommended)

If you are ready to invest in coffee roasting more seriously, the Hottop Roaster is the most advanced roaster on this list. While this high-end machine doesn’t offer a huge capacity, it does enable a high level of control so you can roast with precision and consistency.

An LED screen on the front of the machine allows you to set the roast time, temperature, and fan speed. The machine also allows you to save three roast profiles to easily repeat your favorite roasts. This is a helpful feature if you are roasting the same types of coffee beans each time. In addition to this, there is a USB port allowing you to connect your laptop to the machine. By downloading a program called Artisan you can graph and monitor your roast in real time.  

Roasting with the Hottop takes around 12-16 minutes. The machine has a front-facing window allowing you to monitor the entire roasting process. When the roast is finished, the beans are released into a cooling tray with an agitation arm and fan. This is a nice feature, cooling the beans down in 4-5 minutes.  

The Hottop roaster is a professional-grade roaster that offers a premium build and a high level of control. 


  • Compact design

  • Comes with an external cooling tray

What to Look for in a Home Coffee Roaster?

There are basically two types of home coffee roasters you can buy:

  • Drum Roasters: Drum roasters are the most common type of commercial coffee roasters and involve roasting beans via indirect heat (conduction). Heat is applied to a spinning drum and the beans roast when coming into contact with the drum. These machines often have a larger roasting capacity than air roasters.
  • Air Roasters: Air roasters are the most common type of domestic coffee roasters. These machines work in a similar manner to popcorn machines and use direct heat (convection) to roast beans. Hot air is forced through a chamber containing the beans and they are roasted.

Think about how much coffee you need and how often you want to be roasting a batch. Generally, air roasters are only able to roast small batches whereas drum roasters have larger chambers to cater to a bigger batch.

Manual or Automatic?
How invested are you in coffee roasting? Is this an occasional hobby or a new passion? If you are just starting out it is worth considering a manual roaster. These are a lot more affordable but do have a smaller capacity and require constant attention during roasting. If you are wanting to really get into coffee roasting an automatic roaster is a lot more convenient. These are easier to use but do require a significant investment.

How involved do you want to be in the roasting process? Do you want to just flip the switch and leave it running? Or are you more inclined to tweak different variables for a more unique roast? In general, the higher-end machines have more programmability and allow you to create and save roast profiles for increased consistency. While the lower-end machines only offer basic time and temperature control.

This stage is almost as important as heating. You need the beans to cool down quickly or they will continue to roast. Most home coffee roasters blow cool air through the roasting chamber to do this. Others, like the Hottop, have an external cooling tray which the beans are dumped into.

Ease of cleaning
Roasting can be messy as chaff and smoke are released. Ideally, a machine will have a chaff collection system for easy cleanup and also smoke suppression systems so they can be used indoors. As a side note though, even if the roaster does have a smoke suppression system they still produce a lot of smoke so it is best to roast in a well-ventilated area or outside.

Noise/ visibility levels
If you are wanting to make an art out of roasting you may want to look for a quieter machine so you can hear the first and second cracks and know exactly what stage your roast is at. Similarly, you may want to opt for a machine that allows you to see the beans easily.

Stages of Coffee Roasting

Stage 1- Drying
A coffee bean is made up of about 8-12% water content. In this first stage, it may look like nothing is happening but the bean is warming up and the water starts to evaporate.

Stage 2- Browning
Once the beans have dried out they begin to brown (usually around 150C/ 302F). The coffee bean begins to expand and it sheds its thin skin (the chaff). At the end of this stage, you begin to hear the first crack. This occurs when the pressure inside the bean (from the build-up of gases) is released. It sounds similar to popcorn popping. Light-roasted coffee is usually stopped at or just after the first crack. These beans are a dark tan color and typically have a bright acidity, hints of fruit, a light body, and a lack of bitterness. Origin flavors are more pronounced in a light roast, so if you are using single-origin beans this is a great roast level to aim for.

Stage 3- Development
This is where the art of roasting comes in as the roaster determines how long to subject the coffee bean to heat. During this stage the complex flavors start to develop; the acidity and sweetness of the bean decreases as the sugars and acids inside are caramelized. This will result in a medium-roasted coffee. These beans are a light brown color and typically have a more balanced, sweeter taste with a hint of bitterness. They still have their unique flavors resulting from the origin but these are toned down and smoothed out.
At the end of this development stage, you hear the second crack as the structure of the bean begins to break down and its oils are released. They become darker and oils appear on the surface. This will result in a dark roasted coffee. These beans are a dark brown color with an oily sheen and typically have a low acidity and high level of bitterness. The flavor characteristics of their origin are far less pronounced at this stage.

Coffee Roasting Equipment

So now that you have decided on what roaster you are going to get, what other coffee roasting equipment would it be good to invest in?

  • An extractor fan is a good idea especially if you are wanting to roast indoors, as a lot of smoke is released during the roasting process.
  • Scales are a good investment so you can keep track of exactly how much coffee you are roasting.
  • It would also be a good idea to invest in some silicon gloves, to protect from burns
  • A sieve is a cheap and convenient way to quickly cool down your roasted coffee beans.
  • It would be a good idea to invest in a coffee storage container or some coffee storage bags to store your roasted beans in.
  • Finally, if you are wanting to get serious about coffee roasting you should get the book The Coffee Roaster’s Companion by Scott Rao.

Tips For Roasting Coffee Beans At Home

  • Get some cheap beans initially so you can learn how to use your machine without feeling guilty about the cost. See here for a guide to buying green coffee beans.
  • Set up your roaster in a place with good ventilation. Use an extractor fan or open windows or even consider roasting outside so the smoke released from the beans can escape.
  • Get a notebook and record your temperature, fan or drum speed, roast times, and the outcomes. This means you can duplicate roasts you love and tweak ones you are not so pleased about.
  • Don’t overload the roaster – this will lead to an inconsistent roast
  • Never leave a roaster unattended
  • Keep out of reach of children and pets as coffee roasters can get very hot
  • Leave freshly roasted beans to rest for 2 days before using so they can degas (using beans that haven’t had time to degas will result in an uneven extraction)
  • Store roasted beans in an airtight container and in a cool dark place
  • Grind beans on demand and not too far in advance for the best-tasting coffee

Happy Roasting!
