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, perfect for those roasting for others. On the other hand, if you need a sample roaster to perfectly roast 50 g or 100 g, the Nucleus Link or ROEST L100 Plus would be a better choice.

A major difference between machines lies in the accuracy of temperature measurement and 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 love measuring, documenting, and optimizing everything? Or do you prefer a machine that simply delivers great results without much effort? All machines in our range have been proven to perform – it’s just about finding the one that best fits your style.

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

Automated machines take over some tasks and ensure consistent results – ideal for efficiency and maintaining quality.

Software helps you track and optimize roasting profiles. It’s a must for professionals – but even as a home roaster, you’ll appreciate how valuable it is to monitor your roasting progress.

In most cases, automated machines can also be operated manually – giving you full 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!
