Introducing the Vibiemme Domobar Super Espresso Machine
Vibiemme domobar’s E61 grouphead. In the home espresso machine world, everyone can instantly recognize the saucer-shaped E61 grouphead. Its polished chrome surface not only adds visual appeal but also underscores its practical value. Espresso machines built around this design are favored not just for their aesthetics, but also for their ability to accommodate slight imperfections in barista technique. The market offers many machines based on the E61 grouphead, leading buyers to puzzle over seemingly indistinguishable options.
Highlighting the Vibiemme Domobar Super‘s Features
Let’s delve into the specifications that set the Vibiemme Domobar Super apart:
The iconic E61 grouphead.
Housing comes in stainless steel or black powder coating.
You can choose between manual, semi-automatic, and electronic dosing options.
Three-position power switch for added control.
Generous 2.7-liter boiler and an impressive 3.8-liter water reservoir.
In this review, we will closely examine the factors that differentiate the Domobar Super from other E61-based rivals, helping you to making an informed decision.
Initial Impressions
The Domobar Super is larger than the average E61-clone home espresso machine. With dimensions of 20 inches in depth (excluding a one-inch allowance for the drip tray handle), 10.5 inches in width, and 15.375 inches in height, giving it ample space. While its height is suitable for standard overhead cabinets, it’s advisable to measure up your work area to see if you will be comfortable with the spacing. The machine features both a boiler pressure gauge and a brew pressure gauge at the top front, reminiscent of the popular Isomac Tea’s style. Additionally, there are three indicator lights to give warnings.
The amber light next to the boiler pressure gauge indicates heating element is on.
Another amber light on the left side of the brew pressure gauge signals low reservoir water.
A green power indicator is located on the right side of the brew pressure gauge.
For the semi-automatic and automatic versions of the Super, brew control buttons are conveniently placed between the two gauges. In the case of our evaluation model, the manual version, a lever is situated on the right side of the E61 grouphead.
Exploring the Domobar Super’s Features
The Domobar Super operates as a reservoir type espresso machine, often referred to as “pourover” or “water tank.” Positioned beneath the cup warmer and toward the machine’s rear, the 3.8-liter reservoir is impressive. While many pourover espresso machines feature an open-top reservoir, the Domobar Super boasts a closed tank with a removable refill cap. The cup warming tray extends over the machine’s top and comes with two handles, requiring you to temporarily remove cups to refill the tank.
The Domobar Super comes with two portafilters (one double-spout and one single-spout), a Faema-style double basket, a single basket, and a blank basket for backflushing. Additional items include a traditional black plastic tamper, which might be seen as more of a novelty, and an angled grouphead brush for cleaning the shower screen and gasket, although its design could cause some hand warming. When you buy this espresso machine, make sure to get a 58mm tamper. The manual is pretty standard for espresso machines—kind of dull and not well-written, but you should still read it before using the machine.
Technical Specifications and Setup
The Domobar Super carries a commercial UL rating and necessitates a 120V outlet capable of delivering 17.5 amps to accommodate its 1600W heating element and a 41W vibratory pump. It’s recommended to ensure your kitchen circuits can handle the machine’s power requirements. Most modern kitchens are equipped with several 20-amp circuits, although older kitchens might feature only 15-amp circuits. Notably, the Super comes with a longer-than-average 7-foot electrical cord emerging from the center of the undercarriage.
Setting Up the Domobar Super
The Domobar Super, which means “home bar super” in Italian, doesn’t require any special setup—just plug it into a regular outlet. Vibiemme offers two models: the Domobar and the Domobar Super, each with different features. This review focuses only on the Domobar Super.
Weighing in at 32kg, the Domobar Super is a weighty espresso machine. Get some help when lifting it out of the box. The stainless steel feet need to be screwed onto the machine’s base. These feet have a non-skid material keep the machine in place. If you don’t have a helper, carefully place the machine on its side on a soft pad to get easier access to the bottom. Once on the countertop, the remaining setup is straightforward:
Remove the protective film from the cup warmer.
Fill the water reservoir.
Fill the boiler.
The Vibiemme’s setup is unique with its three-position power switch, a feature commonly found in commercial equipment. The initial (I) position powers the system, activating the pump without energizing the heating element. This position facilitates priming the pump and filling the boiler, allowing water to pass through the heat exchanger and group without heating. Upon filling the boiler and heat exchanger, shifting the switch to its final position (II) triggers the heater, with the amber ‘element energized’ light next to the boiler pressure gauge illuminating.
This three-position power switch proves to be a clever feature. Many semi-commercial espresso machines are equipped with simple on/off switches that power both the pump and the heating element simultaneously. This can pose a risk of burning out the exposed heating element if the boiler doesn’t fill quickly enough during the initial fill. In contrast, the Vibiemme Domobar Super’s first boiler fill is stress-free due to the (I) power switch position, which exclusively powers the pump.
Vibiemme Domobar Super Temperature Control
Just like all heat exchanger machines, controlling temperature in the Vibiemme Domobar Super is achieved through the cooling flush method. For detailed insights into flushing techniques, I recommend reading the article “How I Stopped Worrying and Learned to Love HXs.” Once the machine is heated, I observed that it required less flushing than I initially thought. This applied to both the initial cooling flush and the in-between shot cooling. The Super features a flow restrictor in its upper thermosyphon line. This clever addition maintains optimal group temperature even during extended periods of inactivity. During idle moments, my machine’s group temperature stabilized at around 200°F, give or take a degree. Even after idle periods surpassing four hours, the group temperature never exceeded 202°F, as confirmed by a thermometer I placed in the grouphead water path plug bolt.
Dosing Experimentation and Espresso Results
After experimenting with different dosing levels, ranging from 14 to 18 grams. I encountered some challenges with channeling at lower doses. I could achieve a good shot at a lower dose but with some difficulties. On the other hand, shots at the higher end of the spectrum (above 18 grams) provided ample body in the cup but lacked the more delicate flavors. Ultimately, I settled on a 16-gram dose as best for most coffees.
Espressos extracted from the Super are on par with or slightly superior to other E61 machines I’ve tried. The shots are rich and crema-filled, provided your beans and grinder are up to the task. The cup is abundant with deep flavors such as chocolate, cocoa, and leather. Mid tones like nut and spice are pronounced, while lighter and more delicate notes are somewhat subdued. The cup presents a blend of flavors, though not as distinct as the shots from my regular setup, the Elektra A3. Granted, comparing these two machines might be somewhat unfair due to their substantial differences. When compared to my other E61-based espresso machine, the Isomac Millennium, the Super offers a slightly more rounded cup profile. The pressure ramp adheres to the standard pattern seen in most espresso machines driven by vibratory pumps – a 4-5 second preinfusion followed by full pressure during extraction. A minor pressure drop occurs when the heating element engages, though this isn’t a cause for concern.
Steps to Pulling Shots
Ready to enjoy freshly brewed coffee? Make sure you’ve got everything set:
Ensure an even tamp.
Allow the espresso machine to heat up for 45 minutes to an hour.
Flush water through the group to clear the heat exchanger of super-heated water. The volume of the flush varies based on boiler pressure and desired temperature. Generally, a few ounces suffice if the machine has been idle for a while, and a quick 1 to 2 ounce flush is adequate if it’s been used in the last 5-10 minutes.
Grind your chosen fresh coffee and dose it into the basket. For the double basket, I found 15 grams to be a good starting point for most blends.
Level the grounds in the basket.
Tamp the coffee evenly and consistently.
Lock the portafilter in place.
Lift the brew lever or press the appropriate brew button. The extraction should be steady and slow, with the stream changing from hazelnut-colored with stripes to a blond, translucent appearance.
Enjoy your espresso.
The stock Faema-style double basket works well with a 14-17 gram dose depending on the coffee. Above 17 grams, there isn’t enough headspace, while below 14 grams, you’re getting close to pulling single shots. Overdosing and underdosing to extreme levels can lead to temperamental behavior and potential channeling issues.
Crafting Single Shots
The Vibiemme also comes equipped with a single basket, capable of producing excellent single espressos. Although double espressos tend to take the spotlight, single shots shouldn’t be overlooked. Preparing a satisfying single espresso involves a few key steps:
Aim for a one-ounce drink produced in about 28 seconds.
Given the reduced dose of a single shot, a finer grind is required, necessitating grinder adjustments.
Determine the optimal starting dose, keeping in mind the proper headspace between the puck and the shower screen.
Use a nickel as a gauge to assess the starting dose. Place a nickel on the puck’s surface after dosing and tamping, and then lock the portafilter. Check if the nickel sinks deeply into the puck or causes cracking – both indicate an excessively high dose.
Fine-tune the dose and tamp, keeping a close eye on the headspace and avoiding bottoming out the tamper against the basket’s sides.
Prepare a one-ounce drink with a creamy mouthfeel and rich flavor.
Impressive Steaming Power
The defining feature of the Vibiemme Domobar Super is its substantial 2.7-liter boiler, a full 1.2 liters larger than most other E61 machines. The steam wand, attached via a ball joint on the left side, can be maneuvered in any direction. The wand’s diameter is slightly larger than average, featuring a small rubber grip point for safe handling. The machine’s steaming power is remarkable, capable of creating microfoam perfection. While smaller milk volumes might pose a challenge for newcomers, the steam power is undoubtedly one of the Super’s standout attributes.
Steaming, often considered a challenging skill to master, is made more accessible with the Domobar Super’s capabilities. Cold pitcher and milk, utilizing the correct pitcher size, and maintaining the appropriate steam wand angle are all crucial elements. With these aspects in check, achieving microfoam heaven becomes achievable, yielding perfect lattes and cappuccinos with ease.
Steaming Performance
The Vibiemme Domobar Super excels in steaming performance, evident in the comparative measurements with other machines. The Super’s steaming power is impressively quick, making it an excellent choice for milk-based drinks or entertaining guests with multiple milk beverages.
In essence, the Vibiemme Domobar Super offers an array of features that cater to temperature management, dosing experimentation, espresso quality, single shot preparation, and remarkable steaming capabilities. Its exceptional boiler size, combined with intelligent design, sets it apart as a powerhouse in the world of home espresso machines.
When you lift the Vibiemme Domobar Super, its substantial weight of 32kg immediately gives you the sense of its sturdiness. This machine comes in a lever actuated version, with the lever situated on the right side of the group. In contrast, the semi-automatic and automatic versions have no lever; instead, a side plate conceals the opening, resulting in a sleek and streamlined appearance for the group.
One common issue with many E61 lever groups is the tendency of the 3-way valve, which discharges water into the drip tray, to spray dirty water onto the lower part of the machine. Vibiemme addressed this problem by extending the bottom of the group, allowing high-pressure water to exit directly through the drip tray cover. This design minimizes splashing on the machine’s surface and simplifies cleaning.
Another notable feature is the flow restrictor in the thermosyphon line. Unlike many machines imported into the country, the Vibiemme comes with a flow restrictor that prevents the group temperature from rising excessively. This eliminates the need for excessive flushing before brewing, thanks to the well-calibrated thermosyphon system that warms the grouphead to the desired brew temperature without overheating.
The drip tray consists of two parts and is designed for convenience. The cover comprises a stainless steel frame with a mesh attached, offering ample space. Initially, the fine mesh retains water, but with some use, this tendency reduces. The spacious drip tray is easy to remove like a drawer by grasping the handle and pulling it out to empty.
The Vibiemme Domobar Super boasts dedicated steam and water taps, both equipped with ball joints for flexible movement. These taps are positioned on a valve assembly that angles out from the front of the machine at about a 60-degree angle. While allowing movement in two axes, there is a minor limitation where the taps might contact the valve assembly when moved to the sides of the machine. Nevertheless, this doesn’t significantly affect their usability.
The machine operates as a pour-over model, featuring a large 3.8-liter water reservoir. The reservoir has a sealed top with a removable refill cap to prevent debris from entering the water. The pump’s intake tube is equipped with a screen tip to prevent sediment from entering the system, and the over-pressure valve return line also connects to the reservoir.
Beneath the surface, the Vibiemme Domobar Super impresses with its internal components. The copper boiler and the commercial Parker pressurestat are the focal points. The boiler is well-supported by a robust U-bracket brazed to its underside, which is further secured to the frame. This arrangement relieves stress on the thermosyphon lines, enhancing longevity and minimizing leakage risks. The Parker pressurestat, which directly controls the heating element through contacts, sits high in the frame. Its audible click when the contacts close is noticeable but not overly loud.
Adjusting the pressurestat is straightforward, with a slotted screwdriver inserted into the adjustment screw accessed by removing a small black plug on the inner housing. The wide adjustment range makes fine-tuning the pressure easy. The machine also incorporates a thermal breaker in the boiler to prevent heating element damage. If the breaker trips, it can be reset by pressing the red button.
The over-pressure valve (OPV) is situated at the rear of the machine and controls brew pressure by releasing excess pressure back into the water reservoir. The Vibiemme Super’s commercial-grade OPV can be adjusted by accessing the adjustment screw under the water reservoir. The machine’s thoughtful design includes a spring-loaded stainless steel plate under the water reservoir, housing a pressure switch that cuts power to the machine, except for the low water lamp, when the reservoir is low.
The Vibiemme Domobar Super stands out with its exceptional build quality and features. The thoughtful design addresses various issues commonly faced by espresso machine users. The machine offers different models and options, ranging from lever actuation to stainless steel or black cases, allowing consumers to choose according to their preferences. With its proven E61 heat exchanger design and consistent performance, the Domobar Super offers a unique blend of aesthetics and functionality.
