Expobar · Dual boilerBrewtus IV
The Brewtus IV is a prosumer dual-boiler machine built around a pair of 1.5-liter copper boilers, a Gicar PID, and a modified E61 group with a built-in pre-infusion chamber — serious temperature stability at a price point that undercut most European dual-boiler rivals when it was current.
The short version
A copper-boilered, E61-grouped dual-boiler that punches well above its price class on temperature stability and steam capacity; the trade-off is a utilitarian aesthetic, a lengthy full heat-up, and a product line that has since been superseded by the Crem One DUO-V. Buy used with confidence if you can service an E61.
Why people buy it
- Twin 1.5-liter copper boilers give an unusually large brew boiler relative to the price class, meaning excellent thermal mass and shot-to-shot consistency.
- Enhanced E61 group with a concave pre-infusion chamber improves extraction uniformity without any extra workflow steps.
Why they don’t
- Full dual-boiler heat-up takes roughly 25–30 minutes from cold; the steam-boiler switch helps but it is still not a quick-start machine.
The full tally
- Twin 1.5-liter copper boilers give an unusually large brew boiler relative to the price class, meaning excellent thermal mass and shot-to-shot consistency.
- Enhanced E61 group with a concave pre-infusion chamber improves extraction uniformity without any extra workflow steps.
- Independent steam-boiler switch lets you skip heating the second boiler when you only need espresso, cutting warm-up time and running costs.
- Gicar PID keeps brew temperature tightly controlled and user-adjustable to match different coffee profiles.
- Full dual-boiler heat-up takes roughly 25–30 minutes from cold; the steam-boiler switch helps but it is still not a quick-start machine.
- Utilitarian stainless steel casing and basic aesthetics lag behind European competitors at similar price points (Profitec, ECM) in fit and finish.
- Discontinued in the US market — now replaced by the Crem One DUO-V; parts and retailer support are declining, making long-term serviceability a concern for new buyers.
What the community knows
Years of owner threads, distilled — well regarded.
E61-based dual-boiler with proven serviceability and standard parts availability appeals to homework-doing owners who value balanced workflow over flashy defaults; strong Home-Barista credibility but lower mainstream visibility means you have to actively seek it out rather than…

Worth knowing before you buy — Most owners reason: balanced dual boilers solve the false choice between tiny steam and tiny brew capacity — you get proper volume on both fronts without bloated form factor.
“Big brew boiler, both boilers are 1.5L, no compromise w/ steam. Hard to understand why I'd want a big steam boiler and small brew boiler if I'm only going to use the brew boiler 99% of the time.”
“Steam pressure is crazy good! I only have it set to 1.6-1.7 bar but it goes to 2 which is a lot of steaming power!”

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners typically outgrow the Brewtus IV when they want pressure or flow profiling capability, or when they want better fit and finish. Common upgrades are the Profitec Pro 600, ECM Synchronika, or (for the Expobar faithful) the Crem One DUO-V. Some owners add an outboard rotary pump and ECM joystick steam/water valves as a cost-effective way to extend the machine's capability before upgrading.

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
What are the differences between the Brewtus IV, IV-P, and IV-R?
All three share the same dual-boiler architecture, PID, and enhanced E61 group. The base Brewtus IV uses a vibratory pump and runs on a reservoir only. The IV-P also uses a vibratory pump but adds the option to plumb directly into a water line. The IV-R upgrades to a rotary pump (quieter, lower vibration) and is plumb-only.
How long does the Brewtus IV take to heat up?
Running both boilers from cold takes approximately 25–30 minutes. Engaging only the brew boiler (using the independent steam-boiler switch) can bring it to brewing temperature in under 20 minutes; if you then decide to steam, the steam boiler catches up in roughly another 10 minutes.
Is the Brewtus IV still being manufactured and sold new?
The Brewtus IV has effectively been superseded in the US market by the Crem One DUO-V, which Whole Latte Love describes as an improvement upon the Brewtus. New stock may be available through some international retailers, but it is largely a used-market and closeout item. Factor serviceability into any purchase decision.
What boilers does the Brewtus IV use?
Two independently operated 1.5-liter copper boilers, each with a 2000-watt heating element. The brew boiler benefits from an Expobar-exclusive design in which incoming water is pre-warmed by passing through a heat exchanger inside the steam boiler before entering the brew boiler.
Does the Brewtus IV support pressure profiling or flow control?
No. The Brewtus IV is a straight-pull semi-automatic machine with no native pressure or flow profiling. Some owners have retrofitted an outboard rotary pump or modified the OPV, but this is a DIY path, not a supported feature.
