1. Roasting Volume & Capacity

How much coffee do you want to roast per batch? A machine can be too small – but it can also be too large. The Aillio Bullet, for example, offers a flexible range from 150 g to 1.2 kg, making it perfect for those who roast for others. If, on the other hand, you need a sample roaster to roast 50 g or 100 g batches with precision, the Nucleus Link is the better choice.

One of the biggest differences between machines is the accuracy of temperature measurement and the available control options. Precise sensors and data logging are essential for commercial roasteries, sample roasting and nano lots.

👉 As a home roaster, you should ask yourself: Do you enjoy measuring, documenting and optimizing everything? Or would you rather have a machine that simply delivers great results? All machines in our range have proven themselves – it’s about finding the one that best suits your style.

Manual machines give you full control over temperature, airflow and roasting time. Perfect if you want to actively control the entire process. 

Automated machines take some of the work off your hands and provide consistent results – ideal for efficient workflows and consistent quality. 

Software helps you record and optimize roast profiles. For professionals, it’s often essential – but even as a home roaster, you’ll quickly appreciate how valuable it is to be able to track your roasts.

As a rule, automated machines can also be operated manually – giving you complete flexibility.

• Capacity & Productivity: How much coffee can I roast per batch, both minimum and maximum? How quickly can I start the next batch?
• Control & Precision: What adjustment options do I have for the roasting process? How finely can I control temperature, airflow, and drum speed?
• Temperature Measurement & Roasting Profiles: Is the temperature measured in a way that allows me to compare the data with other machines?
• Energy Source: Electric or gas? What kind of connection do I need? Connectivity: Can I connect the machine to software?
• Mobility: Should the machine stay in a fixed location, or should it also be portable?
• Smoke Development: How much smoke is produced? How can I effectively channel the exhaust?
• Maintenance & Cleaning: How easy is it to maintain and clean the machine? Will I need to replace parts like filters regularly?

All dealers in the EU and Switzerland offer you a 2-year warranty – outside of Europe, it’s usually only 1 year. If you buy your machine outside the EU, you often have to pay high shipping costs for repairs.

👉 Roast Rebels covers all costs for transport, service, and parts in the event of a warranty claim.
Additionally, we have the most important spare parts in stock, so you can keep roasting without delay.

Make sure that your dealer is familiar with the machines and can assist you with questions about roasting profiles or optimization. Often, it’s small tips that can greatly improve your results!
