Kaleido Coffee Roasters

Explore your next roast, from first batch to full production.

Choosing your equipment

Kaleido coffee roasters offer adjustable heat, airflow and drum speed for hands-on coffee roasting. Choose the batch size you will roast most often, then decide whether you want an Artisan computer workflow or a compatible Kaleido tablet system.

Compare M1 Lite, M2 Lite, M6 Pro, M6 Dual and Kaleido M10. Espresso Outlet is the official U.S. distributor; our dedicated Kaleido Roasters USA website provides additional support resources.

Which Kaleido Coffee Roaster Fits Your Batch Size?

Published green-coffee charge ranges
Model	Green coffee per batch	Control choice	Choose it for
M1 Lite	50–200g	Artisan on your compatible computer; no Kaleido tablet support.	Small personal batches and trying different coffees.
M2 Lite	200–500g	Artisan on your compatible computer; no Kaleido tablet support.	Larger home batches within the Lite range.
M6 Pro / M6 Dual	200–700g	Pro: Artisan. Dual: Kaleido tablet plus Artisan compatibility.	Regular larger home batches with a choice of control systems.
Kaleido M10	300–1,200g	M10 packages differ by control system; review the selected listing and included controller.	More green coffee per roast when your normal batch size justifies the larger machine.

Capacity is the green-coffee weight loaded before roasting. Finished weight is lower, and the best charge size depends on bean density, roast style and the temperature probe’s contact with the bean mass. A maximum rating is not a promise of equal results at every batch size.

Plan around your weekly coffee use

At an illustrative 15% weight loss, a 200g charge yields 170g and a 500g charge yields 425g. These are calculations, not measured roast results. Use your own finished weights and allow time for preheating, roasting, cooling and cleaning when planning how many batches you need.

Lite, Pro or Dual System?

Lite and Pro: supply your own compatible computer for Artisan. Windows is our recommended supported setup. The Kaleido proprietary tablet is not a later plug-in upgrade for an Artisan-only controller.

Dual System: the included Kaleido tablet runs the Kaleido interface; Artisan runs on a separate compatible computer. Connection instructions depend on the control board and generation, so follow the guide for the exact machine.

Prepare the electrical supply, computer and roasting space

Kaleido Setup Checklist

Electrical supply: the linked Lite models are 120V. The listed U.S. M6 and M10 models require a dedicated 20A supply; confirm the exact voltage and connection before ordering.
Assembly: Lite cooling boxes require assembly. M6 and M10 heating elements ship uninstalled; follow the supplied instructions and the current setup guide.
Ventilation: electric roasting still creates smoke, heat, odor and chaff. A chaff collector is not a smoke filter. Plan suitable exhaust capture for both roasting and cooling.
Computer: check Artisan, driver and connection requirements before the roaster arrives.
Space: leave access for bean loading, sampling, the cooling tray and cleaning.

Use the Kaleido setup, manuals and connection guide. For 220V needs or help matching capacity to your routine, contact Espresso Outlet.

Can I use the same profile on a different Kaleido size?

A saved curve is a reference, not a transferable recipe. Batch weight, airflow, heating and machine size change the roast. Record your own control changes and compare the brewed coffee.

How do I check stock or preorder timing?

Open the exact product and selected option. New, open-box and different control configurations can have different availability and included equipment.
