The patented IBTS provides unparalleled speed, accuracy, and consistency for the best roasting data available anywhere.

The IBTS: The answer to accurate, real time bean temperature data.

The infrared bean temperature sensor (IBTS) is the patented solution to the biggest 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 with these probes is that they are inconsistent and slow to react to bean temperature changes.

We sidestep the limitations of bean probes altogether by providing a new way to measure the temperature of the beans in the drum: infrared sensors.

This means no lag and remarkable consistency across batch sizes, so that you can repeat your results again and again.

Roast up to a kilo at a time, or use it as a sample roaster.

Whether you’re a professional looking for a versatile sample roaster with extra capacity, or an enthusiast looking to take your coffee to the next level, the Bullet is a uniquely attractive option.

With technology that is unrivalled at any price point, there isn’t another 1kg roaster on the market that can do what it does. The Bullet offers better data, more precise control, and unparalleled ease-of-use — yet it is still one of the most affordable 1kg roasters available anywhere.

More power. Fine control. Better data.
  • Electromagnetic induction heating is highly responsive and easily able to bring a full kg of beans to first crack in under 12 minutes with none of the hassles and danger of gas.

  • Infrared bean temperature sensing provides unparalleled speed, accuracy, and consistency for the best roasting data available anywhere.

  • 9 power levels, 12 fan speeds, 9 drum speeds and a preheat range from 160°C to 310°C allow for fine-control of the roasting process. This is freedom: you are only limited by your own imagination.

  • Precision automatic preheating allows you to dial in your preferred drum temperature for each and every roast

  • RoasTime roast profiling and management software logs every roast for your reference and study, and also grants you access to the Roast.World website, an ever-evolving community where you can share your roasting profiles, recipes, and experiences with other users.

Built to last.

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

Though it wasn’t designed for heavy commercial use, much of the Bullet R1 has been ‘over-engineered’ to ensure a long product life cycle. If you take care of it, it will take care of you.

We do not cut corners. Instead we select components that are built to last. We work closely with our manufacturers and suppliers and carry out QC checks to ensure consistency. 

  • 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 best-in-class, rated at between 6000-10000 hrs.

Easy to set up. Easy to use. Easy to maintain.

The bullet requires very little set up, in fact, its almost as easy as plug in and play. The Bullet does require ventilation which is extremely straight forward and inexpensive to set up. Flexible ducting and a mixed flow fan works perfectly. When you purchase a bullet from us you will receive our ventilation guide with the exact products and set up we use on our own bullet as well as some set up examples, free of charge. 

The Bullet R1 offers such fine control over your roasts that users moving from more simple roasting setups could feel overwhelmed. Unless you keep it simple in the beginning and follow the basic guidelines in the manual, in which case the Bullet R1 is perhaps the easiest hassle-free professional-level roaster for beginners to operate.​


 We highly recommend anyone purchasing a bullet from us to book a place on our ABC's of roasting workshop if possible (based in Amble, Northumberland). We will cover all the basics on getting started with roasting on the Bullet and answer any questions you may have so you can leave confident and excited to get started on your roasting journey. You can even arrange to attend the workshop and collect your brand new bullet on the same day. 

Like all machines with moving parts, the Aillio Bullet R1 needs some personal attention from time to time. But it is quite easy to maintain. You really just need to focus on keeping it clean. There are many fantastic cleaning guides for the Bullet on the internet and from Aillio which you can follow and we are always happy to give advice on cleaning and bullet maintenance.
