The Breville BES878BSS Barista Pro Espresso Machine is designed for coffee enthusiasts who want more control over their espresso without purchasing a separate grinder and espresso machine. Finished in brushed stainless steel, it combines an integrated conical burr grinder, ThermoJet heating technology, PID temperature control, and a manual steam wand in one countertop appliance.
Its biggest attraction is convenience. The integrated grinder handles coffee grinding and timed dosing, while the ThermoJet system is designed to reach its target extraction temperature in approximately three seconds. An LCD display also makes it easier to monitor grinding, extraction time, and brewing settings.
However, the Barista Pro is not a fully automatic coffee machine. It does not independently measure the coffee dose by weight, prepare the coffee puck, or automatically texture milk. Users still need to adjust grind size, distribute the grounds, tamp the coffee, monitor extraction, and operate the steam wand.
This research-based review examines the machine’s design, grinder, heating system, espresso preparation, milk-steaming capabilities, and ownership considerations to help you decide whether it fits your home coffee setup.
Quick Verdict: Is the Breville Barista Pro Worth Buying?
The Breville Barista Pro is worth considering if you want an integrated grinder, fast heating, adjustable brewing settings, and hands-on espresso preparation.
Its ThermoJet system and LCD interface make the workflow more convenient, while the 30-setting grinder provides a useful starting range for dialing in different coffees.
The main compromises are its timed-dose grinder, manual puck preparation, and limited upgrade flexibility. It is best suited to people who enjoy learning espresso preparation rather than expecting the machine to do everything automatically.
What Is the Breville BES878BSS Barista Pro?
The Breville Barista Pro is a semi-automatic all-in-one espresso machine with an integrated conical burr grinder.
The BES878BSS designation identifies the brushed stainless-steel version intended for the US market. Its design combines several functions that would otherwise require separate equipment.
Instead of purchasing an independent grinder, weighing coffee into a separate dosing cup, and transferring it to an espresso machine, users can grind directly into the included portafilter.
The machine also features a digital LCD interface, adjustable shot temperature, low-pressure pre-infusion, and programmable volumetric shot controls.
These features make the Barista Pro suitable for beginners who want to learn espresso preparation as well as experienced home baristas looking for a more convenient countertop setup.
The important distinction is that its automation supports the brewing process rather than replacing the user.

Brushed Stainless Steel Design and Build Quality
The Barista Pro features a brushed stainless-steel exterior that gives it a traditional yet modern espresso-machine appearance.
Its integrated design places the bean hopper and grinder above the brewing section, with the LCD display and control buttons positioned on the front.
The layout keeps the main coffee-making components within easy reach.
Several practical details improve everyday usability:
- A removable bean hopper with a locking mechanism.
- A removable 2-liter water reservoir.
- A stainless-steel 54mm portafilter.
- A removable magnetic tamper.
- A dedicated hot-water outlet.
- A removable drip tray.
- An internal storage compartment for accessories.
- A 360-degree swivel steam wand.
The machine also includes a relatively generous bean hopper for regular household use.
However, integrating the grinder and brewing system into one appliance has a trade-off. If you eventually want to upgrade to a more advanced grinder, you cannot replace the built-in grinder independently without changing the machine’s configuration.
ThermoJet Heating System: Is Three-Second Heating Really Useful?
One of the Barista Pro’s biggest selling points is its ThermoJet heating system.
According to Breville, ThermoJet reaches its target extraction temperature in approximately three seconds. This is considerably faster than the traditional warm-up process associated with many boiler-based home espresso machines.
For people preparing coffee before work, this can make the morning routine more convenient.
The machine also transitions quickly between espresso brewing and steam preparation, reducing the waiting time associated with switching functions.
However, there is an important distinction between reaching the target water temperature and fully warming every coffee-making component.
The portafilter, grouphead, and cup do not necessarily reach their ideal temperatures within three seconds. Breville’s instruction manual recommends flushing the grouphead before extraction to stabilize temperature and preheat the portafilter.
Therefore, the ThermoJet system should be viewed as a fast-heating technology, not a guarantee that every component is immediately ready for brewing.
Integrated Conical Burr Grinder: How Good Is It?
The integrated grinder is one of the most important reasons to consider the Breville Barista Pro.
It uses a conical burr grinding system with Baratza European Precision Burrs and offers 30 adjustable grind settings.
Users can adjust the grind size according to their coffee beans, roast level, and preferred extraction characteristics.
The grinder also supports automatic timed dosing directly into the portafilter.
Understanding the 30 Grind Settings
Different coffee beans require different grind adjustments.
A darker roast may behave differently from a lighter roast, while freshly roasted beans can also require adjustments as they age.
The Barista Pro’s 30 settings provide a practical range for learning how grind size affects espresso extraction.
If the coffee flows too quickly and tastes weak or sour, a finer adjustment may help. If the shot becomes excessively slow or tastes harsh, a slightly coarser setting may be more appropriate.
The machine also has an adjustable upper burr, allowing users to extend the available grind range when the standard adjustment settings are insufficient.
Does Automatic Dosing Mean the Machine Weighs Coffee?
No. This is an important distinction.
The Barista Pro uses timed grinding rather than an integrated precision scale.
Its automatic dosing function runs the grinder for a selected duration. Breville’s instruction manual lists default grinding times of approximately 9.5 seconds for a single basket and 13 seconds for a double basket.
The actual amount of ground coffee can vary depending on the beans, grind setting, and grinder condition.
For more consistent espresso, weighing the ground coffee with a separate digital scale is still recommended.
This is where the Barista Pro’s convenience has a limitation: it automates part of the dosing process but does not eliminate the need for accurate measurement.
Common Grinder Limitations
Independent reviews and owner discussions identify several areas worth considering:
- Grinder noise during operation.
- Coffee clumping inside the grinding chamber or chute.
- Retained grounds between grinding sessions.
- Grind adjustments that may be too widely spaced for certain coffees.
- Differences in dose weight despite using the same timed setting.
For example, Home Explained reported measuring coffee retention of up to approximately 0.5g during its long-term review. Other independent reviewers have also discussed clumping and grinder noise.
These observations do not establish that every BES878BSS experiences the same problems. They do, however, show why a separate scale and regular grinder cleaning can be useful.
Espresso Extraction: PID, Pre-Infusion, and 9-Bar Pressure
The Barista Pro offers several features designed to give users greater control over espresso extraction.
PID Temperature Control
PID temperature control electronically regulates heating to help maintain more consistent brewing temperatures.
The Barista Pro also allows users to adjust the shot temperature through its menu.
This is useful when experimenting with different coffee beans because roast profiles can respond differently to brewing temperature.
Low-Pressure Pre-Infusion
Pre-infusion introduces water to the coffee puck at relatively low pressure before the main extraction begins.
The purpose is to allow the grounds to become evenly saturated before full brewing pressure is applied.
This can help reduce uneven extraction when the coffee is prepared properly.
9-Bar Extraction
Breville specifies a 15-bar Italian pump with a low-pressure pre-infusion stage followed by 9-bar extraction.
The 15-bar figure describes the pump’s nominal rating, not the pressure that should be interpreted as the coffee puck’s extraction pressure.
Volumetric Shot Control
The machine provides single-shot and double-shot presets, along with manual extraction and programmable shot volumes.
The LCD also displays extraction progress and timing.
These features make it easier to repeat a brewing recipe, although users should still evaluate espresso by taste and beverage weight rather than relying entirely on preset volumes.
54mm Portafilter and Manual Coffee Preparation
The Barista Pro uses a 54mm stainless-steel portafilter.
It comes with single-wall and dual-wall filter baskets for different preparation requirements.
Single-wall baskets are intended for freshly ground coffee and give users more control over extraction. Dual-wall baskets regulate pressure and can make preparation more forgiving when using pre-ground coffee.
The machine also includes a removable magnetic tamper and Breville’s Razor Precision Dose Trimming Tool.
The dosing funnel attachment helps reduce coffee spillage during grinding.
Despite these conveniences, puck preparation remains a manual process.
Users must:
- Select the appropriate filter basket.
- Adjust the grind size.
- Grind the coffee into the portafilter.
- Distribute the grounds evenly.
- Tamp the coffee consistently.
- Trim excess grounds when necessary.
- Insert the portafilter and start extraction.
This hands-on process is a central part of the Barista Pro experience.
Milk Frothing and Manual Steam Wand Performance
The Breville Barista Pro includes a 360-degree swivel steam wand designed for manual milk texturing.
It allows users to introduce air into milk and create the microfoam needed for cappuccinos, lattes, and other milk-based drinks.
Unlike automatic milk-frothing systems, the machine does not select the milk texture or complete the process independently.
Users control the wand position, steam flow, and duration of milk texturing.
With practice, this provides greater flexibility for preparing different milk textures and developing latte-art skills.
However, the Barista Pro uses a single heating system rather than a dual-boiler arrangement. Espresso extraction and milk steaming cannot happen simultaneously.
Its rapid heating system makes switching between the two operations quicker, but the user still needs to manage the sequence.
LCD Display and Everyday Brewing Workflow
The LCD display is another practical feature of the Barista Pro.
It shows grinding and extraction progress, making it easier to follow each stage of coffee preparation.
The interface also provides access to settings for grind amount, filter size, shot temperature, and programmable extraction.
For beginners, the visual feedback can make the learning process less confusing.
For experienced users, the ability to monitor shot timing and adjust brewing settings provides useful control without relying on a complicated touchscreen interface.
The machine also includes a dedicated hot-water outlet for preparing Americanos or preheating cups.
Cleaning, Maintenance, and Owner-Reported Concerns
Regular maintenance is necessary to keep the Barista Pro operating consistently.
Its integrated grinder means that users need to maintain both the espresso-brewing system and the grinding components.
Recommended maintenance includes:
- Cleaning the portafilter and filter baskets.
- Removing coffee residue from the grinder.
- Cleaning the burrs according to Breville’s instructions.
- Purging and wiping the steam wand after milk preparation.
- Emptying and cleaning the drip tray.
- Replacing the water filter as recommended.
- Running cleaning and descaling cycles when required.
Some owners report that grinder retention and clumping can affect dose consistency. Others mention grinder noise or the learning curve associated with dialing in espresso.
These are reported experiences rather than confirmed defects affecting every machine.
Breville provides a troubleshooting section in its official instruction manual, including guidance for blocked grinder components, inconsistent dosing, and cleaning.
For long-term ownership, following the manufacturer’s maintenance instructions and checking warranty coverage are sensible precautions.
