The buying decision

Is the Steel Duo right for your setup?

Our interpretation of the documented features. Performance, taste and long-term reliability have not been independently tested.

Who this workflow suits

Steel Duo lets you choose the machine and grinder separately. That gives you separate upgrade decisions, but the grinder belongs in the initial budget and counter plan. Choose it for the adjustment and dosing routine you want, rather than matching the machine’s finish alone.

The tradeoff to think through

The documented heating system is Dual thermoblock. Compare the actual drink-making sequence and milk controls. A manufacturer’s heater-ready claim should not be treated as a measurement of cup temperature, full-system readiness or beverage quality.

Ownership before accessories

Read the cleanup instructions for the exact milk system you will use. Check the manual’s water requirements, coffee-path cleaning and service arrangements before ordering optional accessories. Confirm the supplied baskets, jug, filters or adapters with the selected retailer; a family photograph does not establish what is in the box.

Three grinder workflows to consider

These are espresso-grinder options to research, not a claim of accessory or portafilter-support compatibility.
