The Bullet R1 V2

Probably the best little coffee roaster in the world.


Current Lead Time: 3 Months

Take control of your coffee…

Those who are passionate about coffee tend to obsess over it. We carefully measure out grams, seconds, and degrees. We fret over filters and grind-size. And we fanatically source our beans, happily chasing our favorite varieties to the ends of the earth. But there is one important variable that most of us aficionados have very little control over: the  roasting of the beans.

Enter the Bullet R1, a roaster designed with our fellow coffee geeks in mind. It is a powerful, true drum roaster, easily capable of bringing a full KG of beans to first crack in under 12 minutes – a remarkable feat for a machine that fits neatly on your kitchen counter and plugs into any standard wall socket.

A Roaster Unlike Any Other

It’s the only roaster to use induction as its heat source, making it the most energy-efficient roaster in the world. And it’s also the only roaster that allows roast profiling with infrared, granting its users unparalleled bean temperature accuracy.

The Bullet R1 is highly responsive to user input, giving you fine control over drum speed, fan speed, and heating power during the course of each roast. You can take samples mid-roast using the “tryer”, sneak a peak at your beans through the sight glass, or obsessively monitor the numbers on the LCD control-panel – it’s all up to you. Included in the package is the RoasTime roast profiling and management software, which also grants you access to the Roast.World website, where you can share your roast profiles with other users.

(And let’s not forget that this little roaster also looks very sexy.)


Why use induction?

Whereas traditional electric roasters must rely on heating elements to indirectly heat the drum, the Bullet R1 uses induction instead. Eliminating the need for a heating element accomplishes a few different things.

  • It eliminates energy waste, effectively transforming the Bullet R1 into one of the world’s greenest roasters.
  • It drastically increases the responsiveness of the machine, lending it a feel more akin to gas roasters than traditional electric roasters, as any mid-roast adjustments to the power level are instantaneous.
  • It allows us to pack an incredible amount of heat into the Bullet, reducing its footprint without sacrificing its power, so that you can roast 1kg batches of coffee just about anywhere, with none of the setup headaches associated with gas roasters.



The IBTS: What is it? Why does it matter?

The infrared bean temperature sensor (IBTS) is our patent-pending solution to a big problem in data-driven coffee roasting: bad bean temperature data. Professional roasters have long known that their bean probe is lying to them, vulnerable to a variety of variables that make it difficult to match profiles of different batch sizes across different machines.

The problem is inherent in the very nature of traditional bean probes: they are not all the same, and they are slow to react to bean temperature changes.

We sidestep these limitations by providing a new way to measure the temperature of the bean mass in the drum: infrared.

No lag. Consistent across batch sizes. Good data. You’ll know what temperature first crack will coming in at every time you roast.

Simply put, it’s a better way to roast coffee, and another Aillio exclusive.

The RoasTime and Roast.World Ecosystem

RoasTime is Aillio’s proprietary roast profiling software. You can use the software to both monitor and control your roasts on the Bullet R1. It is 100% free and available for Mac, PC, and Linux systems.

Every change your make during a roast — whether through the software or manually — is logged. Power, fan and drum speed settings, the change in bean temperature, and even the ROR (rate of rise) is stored in each roast profile. This data, when paired with your own cupping notes, will help you level-up your roasting skills.You can *see* each roast, from start to finish, and begin to understand what roasting techniques works best for a particular bean.


But the RoasTime software does much more than log your roasts. It also allows you to Playback roasts automatically — or alternatively, to create your own “Roast Recipes” that trigger automatic changes in Power, Fan, and Drum settings according to either time or bean temperature parameters during the course of a roast.

In addition to all this, RoasTime also connects you to our Roast.World online platform through the Aillio ID system. Here you can analyze your roasts on the web, produce detailed cupping notes, download profiles and recipes from other users, and manage your bean inventories. 

You can also visit the online forum to discuss your Bullet R1 experience with kindred spirits. The Roast.World project is still in its infancy, and we have been improving it incrementally over time, with a major overhaul and new features coming soon.

Designed in Denmark.

Made in Taiwan.

Built to last.

Aillio’s mission from the very beginning was to produce the world’s best coffee roaster for homes and small cafes.

We do not cut corners, but rather select components that are built to last. We work closely with our manufacturers and suppliers, too, and carry out QC checks on a regular basis. Much of the Bullet R1 has been ‘over-engineered’ to ensure a long product life cycle. 

  • Laser cut stainless steel 304 constructions.
  • Precision CNC milled aluminum front plate and door.
  • High-temp nylons that don’t go brittle over time.
  • Electronic components from Japan, USA and Europe.
  • All capacitors are rated at between 6000-10000 hrs – best in class.
