La Spaziale · Dual boilerS1 Mini Vivaldi II
A tank-fed dual-boiler machine from Bologna carrying genuine commercial DNA — simultaneous brew and steam, volumetric dosing, and a patented saturated group, all without requiring a plumbed water line.
The short version
The Mini Vivaldi II is the rare home machine built around true dual-boiler architecture derived from La Spaziale's commercial line, making it a legitimate step up from heat-exchanger machines.
Accept that it runs a 53 mm proprietary portafilter, has no PID, demands a 25–30 minute warm-up, and aesthetics are strictly utilitarian.
Why people buy it
- True dual-boiler allows simultaneous brewing and steaming with independent temperature setpoints — no cooling flush, no waiting
- Vibratory pump is significantly quieter than standard vibration pumps; dual front manometer lets you monitor boiler and pump pressure without a gauge portafilter
Why they don’t
- 53 mm proprietary portafilter is an island — aftermarket baskets, distribution tools, and puck screens require extra sourcing effort
The full tally
- True dual-boiler allows simultaneous brewing and steaming with independent temperature setpoints — no cooling flush, no waiting
- Vibratory pump is significantly quieter than standard vibration pumps; dual front manometer lets you monitor boiler and pump pressure without a gauge portafilter
- Front-accessible water tank and long-proven commercial-grade internals make daily workflow practical and the machine genuinely long-lived
- Programmable volumetric dosing for single and double shots plus 1°C brew-temperature increments (91–97°C) deliver repeatable results without a shot timer
- 53 mm proprietary portafilter is an island — aftermarket baskets, distribution tools, and puck screens require extra sourcing effort
- No PID; temperature control uses a bang-bang thermostat with a ±8°C programmable offset, and the group head is passively heated and needs a full 25–30 minute warm-up for stable shots
- Boiler heating elements are sealed into the boiler bodies — if an element fails, the entire boiler assembly must be replaced, not just the element
What the community knows
Years of owner threads, distilled — well regarded.
Proven workhorse with exceptional reliability and frictionless daily workflow, but sealed boilers and 53mm portafilter limit serviceability and shot-ceiling growth — respected as a durable stepping-stone, not an endgame climb.

Worth knowing before you buy — Most owners who stay long-term wish they'd invested the difference into a better grinder or dialed in beginner expectations around serviceability upfront.
“Couldn't be happier. I make 2-3 cappuccinos a day with this machine and it doesn't miss a beat.”
“I think the Vivaldi excels at allowing you to walk up and pull great shot after great shot without a fuss. I would buy it again.”
“I've had the Mini II for 5+ years. Love it, but no doubt there are better machines for more money. 53mm makes it harder to find some accessories but I've sourced a grooming tool and puck style tamper after a little searching.”

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners who outgrow this machine typically move to a La Marzocco Linea Micra or a spring-lever machine (Londinium, Strega). The 53 mm portafilter ecosystem does not transfer, so there is no accessory carry-over to mainstream 58 mm machines. The plumbed Vivaldi II is a natural lateral step for those who want to add a water line.

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.
- 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
Does the S1 Mini Vivaldi II need to be plumbed in?
No. The Mini version uses a front-accessible water tank (2.4–3 L depending on retailer configuration) and does not require a direct water line. The standard Vivaldi II is plumb-only.
Does it have a PID controller?
No. It uses a bang-bang thermostat with a programmable ±8°C offset differential. The front LED display shows brew temperature in 1°C increments from 91–97°C, and each machine is calibrated before shipping. Temperature stability is good but it is not the same as a true PID.
How long does it take to heat up?
Plan on 25–30 minutes for the group head to reach thermal stability. The boilers themselves come to temperature in roughly 15 minutes, but the passively heated group needs additional time.
What portafilter size does it use?
53 mm — La Spaziale's proprietary size, shared across their commercial line. It is not compatible with standard 58 mm accessories from other brands.
Can I add pre-infusion?
Yes, as an optional add-on. A passive pre-infusion chamber can be attached to a pre-drilled and tapped port on the brew group, functioning similarly to an E61 group pre-infusion chamber.
Is there a shot timer built in?
Not as a standard feature on the Mini version. Volumetric dosing (programmable single and double shot volumes) is included, but a shot timer is an optional add-on referenced by retailers.
