Kaleido M6 Electric Coffee Roaster (CE Certified) – 200g–700g Capacity

Right-sized for cutting your roast frequency further
Owners moving up from a 400g machine describe the M6 as the point where roasting stops being a weekly chore - several run 3-4 back-to-back batches in a sitting, turning what used to be multiple evenings into one session with a proper pound of coffee to show for it.

Headroom without commercial economics
One owner settled on the M6 specifically because their weekly 450g need fit it perfectly, with room to grow — enough that they didn't feel boxed in, but not so much machine that they were paying for capacity they'd never use.

A genuine step into Artisan, same as the rest of the range
Independent bean and environment probes feed a live curve straight to Artisan on Pro and Dual - the same software, the same vocabulary, that scales all the way up to the M10 if you ever outgrow this one.

• Standard – Roasts entirely from the attached 7" touchscreen running Kaleido's own software. No computer needed. No Artisan connectivity.
• Pro – No touchscreen. Driven by Artisan on your Windows or Mac laptop via USB , Wifi or Bluetooth. Kaleido's official Artisan sponsorship means it's properly supported, not an unofficial config file someone's shared online. The cheapest way in if you already know you want full control.
• Dual – Both: touchscreen roasting straight out of the box, and Bluetooth Artisan when you want to go deeper. A nice way to hedge if you're not sure yet how far into profiling you want to go.

Can't be run from an iPad or iPhone - Artisan needs Windows or Mac, and the Kaleido system lives on the machine's own touchscreen (Standard/Dual only).

Is CE marking actually required, or just a nice-to-have?

It's a legal requirement. Under EU Directive 2014/30/EU (the EMC Directive), electrical equipment sold in the UK and EU must carry CE marking backed by a Declaration of Conformity. It isn't optional, and it isn't something a manufacturer can apply retroactively to a machine that wasn't tested - it's tied to the specific production batch that was actually submitted for testing.

Does every roaster with the same model name carry it?

Not necessarily. A machine can be sold under the same model name - M1, M2, M6, M10 - with or without having gone through certification testing, depending on which batch and which seller. The model name alone tells you nothing about compliance status.

What's actually certified here?

The different models we sell has been independently tested and verified by SGS-CSTC Standards Technical Services, confirmed compliant with EN IEC 55014-1:2021, EN IEC 55014-2:2021, EN IEC 61000-3-2:2019, and EN 61000-3-3:2013. We can provide the full verification document on request.

Why does this matter to you as the buyer?

Selling or importing non-compliant electrical equipment is a legal issue for the seller, not something that falls on you as the customer after the fact - but it's still worth confirming before you buy, especially when comparing prices across retailers. Ask any seller directly for their certification documentation for the specific unit they're shipping, not just the model name.

Anyone already roasting regularly on a smaller machine who's outgrowing it - reloading mid-session, or running several small batches a week just to keep up.

Households or hobbyists roasting enough that a 700g machine means real batches, not maximum-capacity ones - most owners settle around 500-600g rather than pushing the ceiling every time.

Anyone occasionally roasting for friends and family alongside themselves - the M6 handles that comfortably, and it's a genuinely common reason owners buy this size rather than the M2.

Probably not the one for you if you're roasting to sell at any real, regular volume - that's a different set of economics and the M10 is the sensible starting point instead. And if you'd rather skip the software entirely, our Standard variant runs from its own touchscreen with no computer needed.

At 700g a batch, expect proper smoke past first crack - more than you'd get from the M2, and no roaster this size gets around it entirely. Most M6 owners roast in a garage with the door open, or run some light flexible ducting out to the open air; a kitchen extractor hood on its own is unlikely to keep pace at this batch size.

Worth knowing: Kaleido's own advice, true across the whole range, is not to hard-attach ducting straight onto the exhaust. Instead, hover a wider intake funnel a few inches away, with a small inline extraction fan if you want more pull. If you don't have a garage or an external vent point, factor that into your decision now rather than after delivery.
