LUCCA · Dual boilerM58 Sunto Espresso Machine
A compact E61 dual-boiler built by Quick Mill in Milan exclusively for Clive Coffee, the M58 Sunto pairs a whisper-quiet rotary pump and OLED PID with a dedicated group-head heating element for faster warm-up and rock-solid shot-to-shot thermal stability.
The short version
The M58 Sunto is the clearest path to a capable, rebuildable Italian dual-boiler without stepping up to full commercial hardware.
Accept that the E61 group demands a 12-minute warm-up ritual and a grinder at least as serious as the machine.
Why people buy it
- Dual-boiler with independent PID on both circuits means genuine simultaneous brew and steam without temperature compromise
- Rotary pump runs significantly quieter than vibratory alternatives, practical for early-morning pulls in shared living spaces
Why they don’t
- 12-minute minimum warm-up is non-negotiable; no auto-on or programmable timer built in — an outlet timer is required workaround
The full tally
- Dual-boiler with independent PID on both circuits means genuine simultaneous brew and steam without temperature compromise
- Rotary pump runs significantly quieter than vibratory alternatives, practical for early-morning pulls in shared living spaces
- Dedicated group-head heating element cuts heat-up to 12 minutes — roughly 40% faster than a standard passive-thermosyphon E61
- Flow-control device available as a factory-installed upgrade, extending the machine's ceiling without replacing it
- 12-minute minimum warm-up is non-negotiable; no auto-on or programmable timer built in — an outlet timer is required workaround
- Clive/Quick Mill exclusive means parts and support run entirely through one US retailer, creating single-point-of-contact dependency
- No pressure-profiling out of the box on the standard (non-flow-control) variant; flow control is a separate, additional purchase
What the community knows
Years of owner threads, distilled — well regarded.
Clive Coffee exclusivity and thin Reddit profile mask a genuinely capable dual-boiler with proven 5+ year longevity and clean shot quality; owned by users who explicitly choose it over Rancilio and don't look back, but Canadian pricing and limited forum footprint keep it off the…

Worth knowing before you buy — Most owners wish they'd found it sooner and stopped shopping — it does what a dual-boiler promises without the hype or the Reddit noise.
“Bought my LUCCA M58 at the end of December 2017 and still in love with her. She has operated flawlessly and produces incredible shots. 5 years later and I see no reason to upgrade.”
“I just upgraded to an M58 from a single boiler rancilio Silvia and could not be happier. The machine is beautiful, pulls great espresso (I paired with niche zero) and is quiet.”

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners rarely outgrow the M58 Sunto as a machine — the usual upgrade impulse is adding the LUCCA flow-control device rather than replacing the machine. Those who chase pressure profiling more deeply may eventually look at the Decent DE1 or a La Marzocco Linea Micra for full digital profile control.

Before it arrives
What completes this machine — the faded pieces can wait.
Water filter / softener — Plumbed-in machines need inline filtration to keep scale out of the boiler — it is cheaper than a repair.
- Water filter / softener — Plumbed-in machines need inline filtration to keep scale out of the boiler — it is cheaper than a repair.
- Descaler & backflush kit — Electric boilers scale up and grouts gunk up — a descaler plus backflush routine is what keeps the machine alive for a decade.
- Coffee scale with timer — Espresso is a ratio. A 0.1g scale with a built-in timer is the single biggest consistency upgrade for any manual machine.
- Knock box — Somewhere to bang the spent puck that is not your kitchen bin.
- Calibrated tamper — The bundled tamper is usually an afterthought; a fitted, calibrated one makes prep repeatable.
- WDT distribution tool — Breaks up clumps before tamping — a cheap fix for channeling on any portafilter machine.
- Espresso cups & glassware — Proper demitasse and latte glasses keep the drink hot and look the part.
Feed it right
Week one is dial-in — and stale beans will lose it.
Coffee more than a few weeks past roast won’t extract predictably, and a new machine gets blamed for it. A machine in this class will show you the difference between roast dates — it deserves beans that change week to week.

Common questions
Can the M58 Sunto be plumbed directly to a water line?
Yes. A ball-valve toggle on the machine switches between the internal 3L reservoir and a direct plumb connection. A braided water line with the appropriate fittings is required and sold separately.
How long does the M58 Sunto take to reach brew temperature?
Clive states 12 minutes to full brewing temperature, which they attribute to the dedicated group-head heating element — approximately 40% faster than standard E61 machines that rely solely on thermosyphon circulation.
Is the flow-control device included with the standard M58 Sunto?
No. The base M58 Sunto ships without flow control. It is available as a factory-installed upgrade on the separately sold 'M58 Sunto with Flow Control' variant.
What grinder does Clive recommend pairing with the M58 Sunto?
Clive recommends a quality burr grinder capable of consistent espresso-range grinds. The machine uses a standard 58mm commercial portafilter, so any well-regarded espresso grinder in the midrange or above is compatible.
Who manufactures the LUCCA M58 Sunto?
Quick Mill, a family-run Italian manufacturer based in Milan. The machine is built to Clive Coffee's specifications and sold exclusively through Clive and authorized dealers.
