LUCCA · Single boilerSolo Espresso Machine with Flow Control
A single-boiler, E61 espresso-only machine designed by Clive Coffee and built by Quick Mill in Italy, priced at $1,495 with a flow-control paddle and PID — no steam wand, no distractions.
The short version
The LUCCA Solo with Flow Control does exactly one thing and does it well: pulls PID-controlled, flow-profiled espresso through a commercial E61 group in a genuinely compact footprint.
Anyone who needs milk steaming in the same machine needs to look elsewhere — that is not a limitation to overlook.
Why people buy it
- E61 group head with PID delivers genuine temperature stability at a sub-$1,500 price point usually reserved for simpler thermoblocks
- Flow-control paddle enables real-time pre-infusion and pressure profiling without any electronic add-on
Why they don’t
- No steam wand and no hot-water tap means you cannot make milk drinks or Americanos without a separate device
The full tally
- E61 group head with PID delivers genuine temperature stability at a sub-$1,500 price point usually reserved for simpler thermoblocks
- Flow-control paddle enables real-time pre-infusion and pressure profiling without any electronic add-on
- Espresso-only design eliminates the temperature recovery penalty of sharing a boiler with a steam wand, letting you pull back-to-back shots at consistent temperature
- Compact footprint and walnut wood touchpoints make it among the more aesthetically refined machines in its class
- No steam wand and no hot-water tap means you cannot make milk drinks or Americanos without a separate device
- Vibratory pump adds noise and, at $1,495, puts it up against HX and dual-boiler machines from other brands that do offer steaming
- Reservoir size is stated inconsistently across Clive listings (2L vs 3L) and heat-up is 10–11 minutes — longer than thermoblock competitors
What the community knows
Years of owner threads, distilled — well regarded.
E61 thermal mass with flow control and no steam function strikes the espresso purist's sweet spot — proven reliability, standard 58mm platform keeps you unfenced, and Clive Coffee backing ensures parts and knowledge stay accessible; the tradeoff is zero milk convenience and…

Worth knowing before you buy — Most owners wish they'd prioritized grinder budget equally — the Solo's shot quality ceiling is real only if the grinder can get you there.
Known weak points — E61 grouphead thermal stability issues under extreme ambient conditions (rare); single boiler limits simultaneous steaming and shot work (by design, not failure)

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners who later want milk drinks without buying a separate frother will move to the LUCCA M58 Sunto (dual boiler, rotary pump, steaming). Those who want to stay espresso-only but add simultaneous hot-water or a larger boiler may look at Profitec Pro 300 or ECM Classika PID territory.

Before it arrives
What completes this machine — the faded pieces can wait.
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.
- Standalone milk steamer — No steam wand on board — a standalone steamer (Bellman, Subminimal NanoFoamer) is how you get a real flat white.
- 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.
- Handheld milk frother — The cheapest path to foam for a no-steam machine — fine for casual milk drinks, not latte art.
- 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. While you learn it, a forgiving medium-light roast keeps dial-in kind — bright enough to taste progress, sweet enough to drink the misses.

Common questions
Does the LUCCA Solo have a steam wand?
No. The Solo is intentionally designed as an espresso-only machine with no steam wand or hot-water tap. If you need milk-based drinks, Clive recommends the LUCCA M58 or X58 instead.
Can I add flow control later, or does it have to come from the factory?
The flow-control device can be purchased with the machine or added as a retrofit later. It replaces the standard E61 brew valve with a manually adjustable needle valve.
How long does the LUCCA Solo take to heat up?
Clive Coffee states the Solo heats up in 10–11 minutes from a cold start.
Can I adjust brew pressure on the LUCCA Solo?
Yes. An externally accessible adjustment screw on top of the machine lets you change brew pressure at the group head — for example from the standard 9–10 bar down to 7–8 bar.
Who manufactures the LUCCA Solo?
It is designed by Clive Coffee and manufactured exclusively for them by Quick Mill in Italy. It is based on the Quick Mill Carola platform with Clive-specific aesthetic and feature modifications.
