The Kaleido M2 Dual System Coffee Roaster is the sweet spot for serious home roasters who want more capacity, more control, and more room to grow. With a 400g batch size, the M2 is ideal for roasting enough coffee to last several days at a time while maintaining excellent consistency and repeatability. Designed for dedicated enthusiasts and espresso-focused users, it delivers professional-level control in a home-friendly electric format.

Dual System Control: Tablet + Artisan Ready
The M2 Dual System includes the Kaleido control tablet, allowing you to roast immediately with no computer required. For advanced users, the roaster can also connect to Artisan software, unlocking detailed roast profiling, data logging, and precise control over heat and airflow. This flexibility makes the M2 equally appealing to intermediate roasters and advanced users who want full transparency into every roast.

Version 2 Sealed Design
Built with Kaleido’s Version 2 sealed airflow system, the M2 offers improved heat stability, airflow consistency, and smoke containment. This results in cleaner roasts, smoother development curves, and more repeatable results—especially important when dialing in espresso-focused roast profiles.

Expanded Capacity for Weekly Roasting
With a capacity of up to 400 grams, the Kaleido M2 is perfectly suited for weekly home roasting. It allows you to roast enough coffee for multiple brew methods—espresso, pour-over, and batch brew—without stepping into oversized or commercial-grade equipment.

Standard 120V Power, Home-Friendly Setup
Despite its increased capacity and power, the Kaleido M2 runs on standard 120V household power. No special wiring or dedicated circuits are required, making it easy to integrate into a home coffee bar or small workspace.

Who It’s For
The Kaleido M2 Dual System is ideal for serious home roasters, espresso enthusiasts, and prosumer-level users who want greater batch capacity without sacrificing control or usability. It’s the go-to choice for anyone who has outgrown entry-level roasters and wants a long-term solution that can evolve alongside their roasting skills.
