Kaleido Coffee Roaster Size Guide

Choosing a Kaleido roaster starts with one practical question: how much roasted coffee do you want from each batch? The M1, M2, M6 and M10 share the same basic sample-to-small-production progression, but their rated green-coffee capacities create very different workflows.

Kaleido Roaster Sizes at a Glance

*Illustrative yield assumes roughly 14–18% roast weight loss. Actual loss varies with coffee, profile and roast level.

Choose by Weekly Coffee Use

Capacity is most useful when translated into batches. Divide the amount of roasted coffee you use each week by the expected roasted yield above. If you drink about 1 kg per week, for example, an M1 requires many small roasts, an M2 requires roughly two to three full-size batches, and an M10 can approach that output in one rated-capacity batch. Leave room for test batches, gifts and the fact that you may not always roast at maximum capacity.

The largest machine is not automatically the best. Smaller batches let you change coffees and profiles more often. Larger batches reduce repetition but commit more green coffee whenever you test a new profile.

Kaleido M1: Best for Samples and Small Batches

The 200 g M1 is the most approachable size for learning roast development, evaluating green coffee and keeping several origins in rotation. Its approximate roasted yield is enough for a few brewing sessions, so it suits someone who values variety more than weekly volume.

Kaleido M2: Best All-Around Home Size

The 500 g M2 is the practical middle ground for many home roasters. A batch can cover several days of espresso or filter coffee without making every profile test a kilogram-scale commitment. Choose it when the M1 feels too repetitive but the M6 would regularly be underused.

Kaleido M6: For Higher Home Use and Small Production

The 700 g M6 fits high-consumption households, shared roasting and small production needs. It gives more output per roast while remaining more flexible than the M10 when you want to rotate several coffees.

Kaleido M10: For Maximum Batch Efficiency

The 1.2 kg M10 is the right direction when batch efficiency matters more than frequent variety. It is the strongest fit for people supplying a busy household, office, events or a small roasting operation. Before choosing it, confirm that your ventilation, green-coffee storage and roasted-coffee demand match the larger workflow.

LITE, Pro or Dual System?

Size determines batch capacity; the control package determines how you interact with the roaster. Artisan-system models are built around computer-based profile control and logging. Dual System configurations combine Artisan compatibility with Kaleido’s dedicated tablet interface. Choose the control setup based on whether you prefer a computer-centered workflow, a dedicated controller, or access to both.

Final Decision Checklist

• Estimate your weekly roasted-coffee use.
• Decide how many batches per week feel realistic.
• Allow room for roast weight loss and profile testing.
• Choose smaller if variety and experimentation matter most.
• Choose larger if repeatable volume and fewer roast sessions matter most.
• Confirm electrical, ventilation and workspace requirements on the exact product page.

For most home roasters, the M2 is the balanced starting point. The M1 favors experimentation, the M6 serves higher-volume enthusiasts, and the M10 prioritizes batch efficiency.
