Before we dive into the specs of our key features, let’s take a look at the process of roasting from home and why having your own personal coffee roaster will give you a better-tasting brew. 

Roasting Coffee At Home 

What better place to roast?

How Does It Work? 

The coffee roasting process begins with the harvest. Raw coffee beans are wrapped inside a small red fruit known as the cherry. From there, the skin (or the exocarp), the pulp (mesocarp), and the inner skin (parenchyma) are removed while the coffee bean is left to dry. 

At this stage of the harvest, the raw coffee bean is green, and decent quality green coffee beans can be stored for a lot longer than our familiar, brown coffee beans. 

Once the green coffee beans are roasted, they double in size and turn that dark brown color. Moisture is forced out of the bean as it dries and expands, while natural sugars allow for carbon dioxide to be released. In other cases, the CO2 caramelizes, and that’s where you get unique flavor profiles.

The Cracks 

As coffee is roasted, direct heat plays a major role in the custom profile of your roast coffee beans. This is known in the industry as ‘the cracks.’

You can have up to three consecutive cracks in the roasting process, and, you guessed it, they correspond with your roast profile: light roast, medium roast, or dark roast, with darker roasts taking the longest to finish. 

This is why precise temperature controls are so important, and over-roasting can lead to that burnt, bitter taste in your roast coffee beans. The cracks themselves sound like popcorn popping; that’s how you know you have roasted coffee goodness. 

Is A Coffee Bean Roaster Machine Worth It? 

Popular opinion and coffee experts everywhere agree that decent quality roasted beans should be used between 2 to 14 days after being exposed to a heat source.

To put it plainly, if you’re roasting at home, you’ll get a better-tasting cup of coffee. If you order pre-roasted beans, it could very well take up to 14 days to ship to you. They have more of a chance of de-gassing CO2 levels, which will make your custom profile coffee lose flavor. 

If you’re ordering green beans to roast your coffee at home, you’re at a whole new level of coffee love. You’re joining the ranks of time-honored tradition and farmers from around the world who’ve perfected the art of roasting for centuries to produce top-notch quality roasted beans. 

In-Depth Of Our Top Picks 

Let’s take a look at the list of our top picks and find the coffee bean roaster machine that’s right for you; starting with our best overall, the Kaldi Motorized Home Coffee Roaster. 

1. Kaldi Motorized Home Coffee Roaster – Best Overall

At A Glance
  • Roast Capacity: 300 grams
  • Material: Stainless steel
  • Size: 14″ L. 8″ W. 22.” H.
  • Weight: 14.6 lbs.

SUMMARY: There’s no comparison to the professional-grade Kaldi, with even roasting settings that provide a consistent air-roasted bean in just 10-15 minutes.

Legend has it a goat-herder named Kaldi discovered the coffee cherry in the ancient forests of Ethiopia. He found that the goats who ate these berries had more energy for the long treks across the plateau.

Later, Kaldi found that roasting the green beans and drinking them gave him more energy for evening prayers and kept him awake. Kaldi was an innovator, and it’s only right that the personal coffee bean roaster machine that shares his name has revolutionized the coffee world.  

The Best Around

The Kaldi is our best overall pick, providing consistent quality roasts and sporting many impressive key features; I could write more than just a few paragraphs. But in the spirit of brevity, let’s keep this short. 

The Kaldi Motorized Home Coffee Roaster is a semi-commercial air roaster that offers even heat distribution and a consistent roast every time.

Inside this baseline model are drums coated in perforated copper to prevent your beans from burning and rotate at 65 RPM for freshly roasted coffee in 10-15 minutes. 

For added consistency, the machine has a built-in thermometer so you can monitor and adjust your roasting settings on the control panel using the electronic controls to get a perfect roast. 

The Kaldi’s chaff collector holds more than other batch coffee roasters, meaning you have less of those pesky husks and dried skins to clean up in and around your roaster. 

There’s also a removable probe rod so you can test for fresh flavor, experiment, and find what custom roasting profiles work best for you. 

It roasts 300 grams at a time, or 10 ounces, which translates to about 30 cups of coffee. Depending on what kind of coffee drinker you are, one roast process could last almost a month. 

The Kaldi works best on gas stoves, although it will suit any kitchen with proper ventilation. There’s no smoke suppression or smoke reduction tech, which seems to be the only potential drawback to an otherwise impressive coffee bean roaster machine. 

Pros
  • Probe rod makes for easy sampling of your roasted coffee goodness
  • High-capacity chaff collection 
  • Minimal maintenance required 
  • Built-in thermometer shows precise temperature settings of the drum 
  • Drum roaster opening allows you to effortlessly hear the cracks
  • Drums are coated in copper so your beans won’t scorch 
  • An air roaster that can give you up to 30 cups of coffee per batch size
Cons
  • Biggest drawback is no smoke reduction tech

2. Nuvo Eco Ceramic Coffee Bean Roaster – Best Budget

At A Glance
  • Roast Capacity: 70 grams
  • Material: Ceramic with genuine cowhide grip 
  • Size: 5″ L. 5″ W. 9.5″ H.
  • Weight: Less than 1 lb.

SUMMARY: The best budget roaster for beginners and hands-on people, with roasting settings over an open flame. 

The Nuvo Eco is the perfect coffee bean roaster machine for people on a budget or for the casual coffee drinker who’s always wanted to try roasting their own beans but doesn’t know where to start. 

The Nuvo uses the old-school roasting process of thermal conductivity. By placing the machine over a gas-powered stove or open flame while tracing figure 8’s over the heat, you’ll have successfully roasted decent quality coffee. 

You’re in the driver’s seat, and because you’re manually agitating your beans, this can be fun with a bit of added theatre to your personal coffee roaster. You get to experience the history of the ancestors and how coffee was roasted centuries ago. 

The Nuvo’s design is timeless and polished, looking almost like it was my grandpa’s pipe. It would make a welcomed addition to any shelf or cabinet as a decor piece rather than being tucked away in a drawer somewhere. 

The open hole on the top allows you to use aroma and the clear cracking sound to tell when your beans are finished their roast. 

This is our lowest capacity coffee bean roaster machine on the list and is best for a casual coffee drinker. 

Pros
  • Affordable manual coffee bean roasting machine for beginners 
  • Open hole at the top makes it easy to tell when your beans are done 
  • Added bit of excitement in the roasting process made for hands-on people
  • Sleek ceramic design in these excellent models doubles as kitchen decor
Cons
  • Diminutive size is the biggest drawback and makes for the lowest capacity baseline model on our list 
  • Will take elbow grease to find the perfect roast

3. Sandbox Smart R1 Coffee Roaster – Best Premium Pick

At A Glance
  • Roast Capacity: 100 grams
  • Material: Stainless steel bean tank with aluminum alloy outer case
  • Size: 10″ L. 10″ W. 9″ H.
  • Weight: 15.5 lbs.

SUMMARY: A batch of coffee beans made through totally automated roasting settings; meet the Sandbox R1. 

The Sandbox R1 is the creme de la creme of consistent quality roasts and is for the prosumer coffee purist. 

The electronic controls are automated and use a Bluetooth app. Your coffee roasting machine takes the guessing out of roasting. Just preset your custom roasting profiles to which roast you’d like, and there you have it; no listening for cracks. 

The R1 features a customizable experience with custom profiles for controlling fan speed, drum speed, and precise temperature controls. Consistent quality roasts are made fully electric, with preset profiles and a robust design. 

This is also a roaster that’s easy to maintain and clean. There is mediocre chaff management for catching skins from your roasted batch of beans paired with excellent ventilation from the cooling stray. 

This is an automated air roaster with lots of control options to match your high-tech lifestyle, perfect for smart home lovers. 

Pros
  • Automatic roasting via Bluetooth app with 6 preset profile slots for a fully electric model 
  • Custom roasting profiles for top-notch quality 
  • Easy to clean and maintain 
  • Best ventilation system of our top picks, so no need for the stove fan 
Cons
  • Can take slightly over 15 minutes because of the 30 RPM max drum speed 
  • Biggest drawback is the small beans per batch ratio

4. DYVEE Gas Burner Coffee Roaster – Best Aesthetic Design

At A Glance
  • Roast Capacity: 400 grams
  • Material: Stainless steel and quartz glass 
  • Size: 15″ L. 8.25″ W. 8.5″ H.
  • Weight: 11.5 lbs.

SUMMARY: A personal coffee roaster for hands-on people that lets you see into the drum as you roast. Made to be a marvel of design that gives you a decent quality roast every time.

The DYVEE is a gas power machine that is sure to turn heads and give you all that roasted coffee goodness. This is a coffee bean roaster machine for people who want an excellent cup of coffee and a beautiful, aesthetic roaster all in one. 

Primarily made of stainless steel, the drum is made of quartz glass, with the same going for the glass lid. You get to see every bit of the process of making this coffee bean roasting machine, almost like dinner and a show but with coffee goodness. 

The manual turning operation also gives the DYVEE more of a hands-on experience. You won’t have the same electronic controls you may be used to, but it does give you a more even roast. You have many control options based on how you manually rotate the drum to find the perfect custom roasting profiles. 

At only 11.5 lbs., the DYVEE is lightweight but can still compete with larger models, with a capacity of almost a full pound of beans or one pound per batch. 

That works itself out to 40 cups of coffee and is among the list of excellent models for households with more than a casual coffee drinker; 40 cups makes it akin to commercial coffee roaster machines. 

There is no onboard power supply for this roaster, and it works best on a gas-powered stove or gas-power hot plate. But get your stove fan kicking; this roaster tends to get a little smoky. 

Pros
  • Larger capacity coffee roaster at 400 grams of beans gives the DYVEE a robust design 
  • Marvel of design; lets you see every minute of the roast process 
  • Even bean coverage for precise temperature controls 
Cons
  • Biggest drawback is the slow roast process because of batch size and manual roasting 
  • With no smoke reduction tech, it can get a little smoky

5. Fresh Roast SR540 – Easiest To Use

At A Glance
  • Roast Capacity: 113 grams
  • Material: High quality plastics
  • Size: 6.75″ L. 6.75″ W. 13″ H.
  • Weight: 6 lbs. 

SUMMARY: A popular option for beginners, with 9 different fan speeds and heat settings on the control panel; a fully automatic personal coffee roaster with onboard power supply.

The Fresh Roast SR540 gives you roast coffee beans at the easiest, most user-friendly level. Simply turn the nob between 9 different roasting settings on the control panel for heat direction, leave it for 10 minutes, and there you have it, coffee roasting like that! 

The SR54 stands out for its precise temperature controls and makes custom roasting profiles totally customizable to your heat preferences. It also comes with a real-time temperature reader built into the control panel and the ability to cool your beans after roasting. 

This is a roaster for people who have always wanted to try roasting their own beans but find the process and the price tag intimidating. 

This coffee bean roasting machine can still compete with the top-notch quality roasters out there. Yet, coffee roast reviews agree that it’s a little small for the coffee purists who drink a lot of java and has a poor chaff management system. 

Pros
  • A roaster for people who are beginners 
  • Fast roasting speed of fewer than 10 minutes 
  • Highly adjustable roast settings and lots of electronic controls
  • Built-in cooler for your roast coffee beans after they’ve finished 
Cons
  • Biggest drawback is the diminutive size at only 113 grams 
  • Subpar chaff collector 

6. Wabash Valley Stainless Steel Whirley Popcorn Popper – Best Alternative Roaster

At A Glance
  • Roast Capacity: 5000 grams (HUGE!)
  • Material: Stainless steel
  • Size: 16.5″ L. 9.5″ W. 8″ H.
  • Weight: 2.5 lbs.

SUMMARY: High pound per batch quantity and quick roast time make the Wabash Valley Popper a stand-out among coffee roaster reviews and alternative coffee roasters machine brands.

A popular option among coffee lovers who don’t have access to batch coffee roasters has always been popcorn poppers. 

Similar to coffee bean roaster machines, a popcorn popper operates the same way by listening for the cracks and evenly distributing heat through your green beans. 

While this may not satisfy the coffee purist, you can still have a decent quality roast in a fraction of the time, at less than 5 minutes, with the Wabash Valley Popcorn Popper. 

With a staggering capacity of over 10 lbs., the Wabash is more like a commercial coffee roasting machine than a baseline model or a smaller scale machine. This is a roaster for people who are a little more hands-on and want dual usage out of their coffee bean roasting machine. 

While your stove fan could very well be in overdrive with the Wabash, I’d recommend using this outside as much as possible. Because of the lack of smoke reduction tech, and the enormous batch size of over 10 pounds, your kitchen may look more like Snoop Dogg’s than a coffee haven. 

Pros
  • Larger capacity of over 10 lbs. 
  • Roasted coffee goodness in less than 5 minutes 
  • Dual usage coffee bean roasting machine that makes theatre-like popcorn
Cons
  • Biggest drawback is you’re unable to monitor your ongoing roast without frequent stirring and checking
  • No smoke reduction tech; wouldn’t recommend using with gas power or gas stoves 
  • Limited versatility could lead to uneven roasts 

Buyer’s Guide 

Everyone has different must-haves and must-have-nots when it comes to a purchase, especially one like investing in a better, at-home coffee routine. Here are some things to consider when buying your own personal coffee roaster.

Size

How many grams of coffee beans is going to do the trick? Batch coffee roasters come in all different sizes, and it’s important to consider how often you’d like to roast. 

At home coffee drinkers who want green coffee beans all day every day, you may want to look into the Kaldi, the DYVEE, or any drum-style roaster above 300 grams in capacity.

With a smaller bean capacity, the 10-15 minutes for your coffee to roast every day, and then let alone brew, makes your routine into more of a waiting game than savoring the sweet taste. 

Drum-style roasters below 300 grams of coffee beans are more intended for occasional use. If you’d like to experiment but are married to your Nespresso machine, you could still get away with a smaller, mini coffee roasting machine like the Fresh Roast SR540 or the Sandbox R1. 

Design

Boiling it down to two key features that divide coffee roaster reviews: technology and aesthetic. 

Hands-on people will prefer the art of the manual roaster because it gives coffee drinkers a sense of theatre and accomplishment when they’ve achieved that top-notch quality. You more or less get the same roast every time without the bells and whistles. 

Tech lovers, on the other hand, love lots of control options, custom profiles, and electronic controls for a precise, automatic roast. The magic of creating the roast yourself is replaced with the possibility of customizing your beans down to the minute detail. 

It’s totally up to you, and you should consider if you want to work for your roast or if you want your roaster to work for you.  

Aesthetically, we have a roaster like Sandbox R1 designed to look like the roaster of the future and give you roast coffee beans tailored specifically to you. Meanwhile, the Nuvo has a time-honored, old-school feel; the Kaldi has an industrial, Brooklyn coffee shop charm that requires gas power but is not one of the larger models. 

Aesthetic goes hand-in-hand with the tech you can expect from your roaster. Think about why you wanted to roast your coffee in the first place: to have a little slice of coffee tradition or to streamline your way to the best custom roasting profiles. 

Budget 

For how much you want to invest, I’d consider thinking about how often you drink your coffee and your experience level with roasting. 

If you’re a casual coffee drinker or someone who’s just starting out with roasting green beans at home, I’d recommend looking for a baseline model that’s a more affordable roaster and user-friendly. Try the Nuvo, the Fresh SR540, or the Wabash Valley Stainless Steel. 

If you’re a coffee fiend who’s roasted before, or even if you have always wanted to try it and don’t mind the learning curve, I’d recommend getting a durable roaster with advanced operation. Excellent models are the Kaldi, the DYVEE, and the Sandbox R1. 

The Verdict 

It wasn’t even close; the Kaldi Motorized Home Coffee Roaster wins by a landslide. I chose this roaster as the top overall pick for two reasons. 

1) Consistent Quality Roasts. Featuring copper-coated drums, a detachable probe rod, and a built-in thermometer, you’ll get a high-quality, consistent roast coffee bean every time. 

2) Practicality. With high capacity chaff collection, minimal maintenance required, and a sleek, stainless design, this roaster is built to last and give you roast coffee beans easily and without overworking your stove fan.

So there you have it, the other excellent models just couldn’t compete with the Kaldi. This machine will make a welcomed addition to your coffee experience and will allow you to effortlessly get into the fine, exclusive world of roasted coffee goodness.
