Please Note: The Brewtus II is a redesign of the original Brewtus. Improving on the first model, the Brewtus II features a brewing pressure gauge (in addition to a steam pressure gauge), a brewing pressure adjustment knob that is located behind the drip tray, and a no-burn steam wand. The original Brewtus model is no longer available.

Recommended by David Schomer as "the best machine for the home user," the Expobar Brewtus II double boiler espresso machine with digital temperature control is the result of a groundbreaking collaboration between the Whole Latte Love tech department, customer service staff and the craftsmen of Expobar. Over a year in development, this semi-automatic was exclusively created with us and for us in response to our customers’ needs. Its sole reason for existence is to produce unwavering temperature control. From stability to adjustability, the Brewtus II’s temperature is – hands down – the most accurate and stable on the market today. This is because we developed a list of features the machine had to have, including a double boiler system (both with auto refill) with their own powerful heating elements, a red digital temperature control that’s right on the front of the machine for easy use, the uncompromising E61 brew group, a commercial caliber chrome-plated 58mm portafilter, and adjustable brewing pressure that can be monitored through a new pressure gauge. These features, combined with Expobar’s already exceedingly high standards and dedication to craftsmanship, result in a prosumer machine that performs exactly how our customers have requested.

Along those lines, the Brewtus II also has a super-sized 90-ounce removable reservoir – complete with low water sensor – so you never run dry or burn out the heating elements. It also has a large removable drip tray that can hold up to 64 ounces of liquid before it needs to be emptied. On the top of the machine is a stainless steel passive cup warmer, which is also removable for cleaning and to let you get at the reservoir. The Brewtus II also features a freewheeling stainless steel steam wand and a fully pivotal stainless steel hot water wand, each activated by their own dedicated hard black plastic star shaped knobs. Rounding out the front of the machine are two pressure gauges - one displaying brewing pressure and another showing steaming pressure - the on/off rocker switch and steam boiler indicator light. And to top it all off, the Brewtus II’s brewing pressure can be adjusted using a knob that can be accessed by removing the drip tray.

The Brewtus II is also a handsome machine, with traditional styling, as is the case with the entire Expobar line. It is encased completely in polished stainless steel and will make a striking impression on any countertop. And it’s heavy too, in fact it’s a walloping 61 pounds. But what do you expect from a machine that’s got so much muscle packed onto it? It’s the perfect little powerhouse for any home or small office environment.

The Brewtus II comes with a few goodies too. Its accessories include a tamper, single shot filter basket, double shot filter basket, backflush disc and a 7 gram coffee scoop.

Features & Benefits: Coffee

Heavy Duty Commercial Portafilter

The Brewtus II's portafilter is commercially designed and made of chrome-plated brass, which is ideal for temperature stability throughout the critical end stages of the brewing process. It is a dual spout, 58mm portafilter that weighs in at a hefty 22 ounces, and comes with two filter baskets – a single shot and a double shot.

E61 Commercial Brew Group

In keeping with the Brewtus II's focus on unwavering temperature stability, this machine features the E61 brew group – the industry’s best. Made of solid chrome-plated brass, this entire assembly is revered worldwide for its ability to retain heat at an absolutely consistent temperature. Starting with the group head – the round chrome-plated brass piece on the front of the machine that the portafilter locks into. Inside, it’s channeled for the water to run through it as it travels to the coffee grinds. These channels make up the thermal siphon system which keeps the water at the exact temperature it was in the boiler until the moment it is forced through the group head and down through the coffee. Locking into the group head is a heavy chrome-plated brass 58mm portafilter, which hold the stainless steel filter baskets tamped with coffee. The Brewtus II comes with two filter baskets – a single shot and a double shot. You can also order a special filter basket that holds pods if you prefer to use pods to brew your espresso.

Completing the brew group is the 3-way valve which operates off a manual lever on the front of the Brewtus II. This allows you to control the initiation of the brewing process and the depressurization process yourself.

Progressive Coffee Infusion

The brewing system provides a smoother delivery of pressure than many machines in its class. This makes it possible to perform what is the equivalent to pre-infusion, which is a moistening of the grinds before the full force of water comes through them. This is important because it prevents the water from “channeling” through the grinds and therefore not getting the maximum flavor and aroma out of them.

Commercial Design Double Boiler System Construction

They each have their own dedicated 975-watt heating units, which make it possible for them to run at their respective precise temperatures to perform their respective tasks. Again, this goes back to the Brewtus’ main purpose: unwavering temperature stability. Two boilers means there’s no switching boiler temperatures as you go back and forth between steaming and brewing. Each boiler is set to right temperature for its function. Double boilers also make it possible to brew and steam at the same time, which is perfect if you’re making a few drinks at once. And because the boilers are so large and automatically draw water from the reservoir on their own accord, you eliminate any wait time between shots because you never run out of water or need the water to get up to temperature.

Now, you would think all that power would put a drain on your electric system. But we’ve even taken that into consideration and designed the Brewtus II to work off a standard 15-amp household breaker.

Digital Temperature Control

Again, in deference to the Brewtus II's quest for the perfect brewing temperature, it features a digital temperature control that’s right on the front of the machine. You can make the brew boiler hotter or cooler if you prefer, simply by pressing the up or down arrows on the display. The temperature is adjustable in 1°C increments should you care to change it. This eliminates the need to temperature surf or guess at the proper temperature.

Brewing Pressure Controller w/Pressure Gauge

The Brewtus II's brewing pressure can be monitored using the corresponding pressure gauge on the front of the machine. The brewing pressure can also be adjusted using a knob that can be accessed by removing the drip tray.

Unique Lever Control w/ 3-Way Valve

There are only two controls on the Brewtus. The main power switch is located on the upper left and a big manual lever to the right operates the brewing process and 3-way valve. The main power switch is a lighted rocker switch – when the machine is turned on it glows red, and the boilers immediately start to heat up. When the pressure gauge reaches 1 bar of pressure, you are ready to brew. The only control you will need to operate is the lever that is located just to the right of the brew group. This is a very unique system because this lever actually controls a valve in the brew group. Press the lever up to open the valve to start the water flow through the coffee. This also activates the pump. Press it all the way down when you are done brewing and it opens a valve that relieves the water pressure off the coffee. This serves two functions; it dries out the coffee to prevent dripping and makes it easy to knock the coffee out of the portafilter with one knock. This valve that you are operating is a very high quality piece of equipment that gives you more of a hands on system that most standard pump machines. And because the valve has no electrical charge running through it, and therefore few parts, it is more reliable than the electric solenoid valve.

Low Water Cut Off

The Brewtus II has a low water sensor mounted under the water reservoir. It operates similar to a scale. If it notices the reservoir feels to light, it will turn off all power to the boiler because that means the water level is too low.

Steam Pressure Controller w/Pressure Gauge

The steam boiler temperature/pressure is controlled through a pressure controller. It senses the pressure in the boiler and turns on the heating element in the boiler as the pressure drops. You can visually see the boiler pressure through a pressure gauge on the front of the machine. When the needle in the gauge is between 1 and 1.5 bar of pressure you are ready to steam. The red indicator light will go on when you are engaging the steam boiler. When you are done steaming and the machine returns to pressure, the light will go off.

If for some reason, the pressure controller ever gets out of calibration you can tell by the pressure on the gauge. Just give us a call and we can easily walk you through resetting the pressure controller.

Electronic Controls

The "Electronic Boiler Refill Control" is the brain of the machine. It uses probes mounted inside the boiler and on the base plate below the reservoir to sense the water level. It uses this information to control the operation of the pump for refilling the boiler when necessary. It will also turn the boilers off for safety if the reservoir or boilers run out of water.

Cup Warmer

You have a machine that is dedicated to temperature control. So why would you pour your espresso into a cold cup? It would immediately suck the heat out of the espresso thus robbing you of maximum enjoyment and everything the machine just worked so hard to achieve. So warm your cups on the passive cup warmer that takes up the entire top of the machine. Because it’s warmed by the heat that’s given off from both boilers, it will keep all your cups extremely toasty. Some passive cup warmers have “cool spots” where the heat from the boilers can’t reach. But the Brewtus II's double boiler system completely eliminates this. And the cup grate is made of stainless steel to conduct the heat evenly across the surface, adding to a uniform temperature. It is removable for easy cleaning or access to the reservoir.

Features & Benefits: Frothing and Hot Water

Hot Water Dispenser

The Expobar Brewtus II has a separate stainless steel hot water dispenser. Mounted on a ball joint, the dispenser swivels in all directions giving you easy access. Just turn the black knob above it and you’ll have all the hot water you’ll need for Americanos, tea or cocoa.

No Burn Steam Wand

The steam wand is also made of stainless steel and is mounted on a ball joint. While this is nice for access, it also makes it easy to use when you want to froth. Plus, the interior of the steam wand is lined with Teflon so you don’t burn your fingers when using it. The steam wand’s tip is a commercial one-hole model. This is great for steaming or frothing 8 ounces of milk at a time.

Features & Benefits: Care, Maintenance & Other

Water Reservoir

The 90 oz plastic reservoir is easily removed or refilled from the top of the Brewtus II. Tucked inside the machine to the left, simply lift the cup warmer to get to it.

Maintenance

Back flush the Brewtus II at least every 7-9 days. It is a simple process that takes only a few minutes. Put a blank filter basket into the portafilter (supplied) and add a 1/2 teaspoon of cleaner. Install the portafilter into the machine and turn the control lever up to start the pump. The pump will be noisy as it starts and will quiet down as the pressure builds. When the pump has quieted down, turn the lever all the way down. This will cause the cleaner to be blown up into the brew group, through the 3-way valve, and down into the drip pan. Do this until the cleaner that is being directed into the drip pan is free of coffee colors. Finish the process by rinsing out the brew group.

Housing Construction

The Expobar Brewtus II is shiny and sleek. Its traditional design is housed in polished heavy-duty stainless steel housing. The cup warmer, drip tray and drip tray cover are also stainless steel to match. And the chrome plated brass brew group blend perfectly with the rest of the machine. All this needs to be held up by a very strong frame, and the Brewtus II's frame is just that. It is constructed of a heavy gauge stainless steel, which contributes to the machine’s hefty 61 pounds.
