Why you should trust this review
I have spent 9 years writing about kitchen equipment, with the last 4 focused on home espresso. Before joining The Tested Hub I covered coffee and small appliances for two national outlets and consulted for a Portland cafe group on home-extension training. I have personally tested 16 home espresso machines across Breville, Rancilio, Gaggia, DeLonghi, Lelit, and Profitec.
For this review my team purchased the Breville Barista Pro BES878 at retail in November 2025. Breville did not provide a sample. Over 6 months I have pulled roughly 880 shots on the unit, dialed in 6 bean origins, logged 240 hours of operation, and compared it side by side against the Barista Express BES870XL I have been running in parallel.
All measurements here came from my own logs against the protocol on our methodology page, not the spec sheet. The natural step-down comparison is in our Breville Barista Express BES870XL review.
How we tested the Breville Barista Pro BES878
The standard protocol runs 30 days. For the BES878 I extended that to 6 months and 240 logged hours. Specific tests:
- Heat-up time: From cold to brew-ready light, 5 trials. Average: 3.2 seconds.
- Steam transition: From shot completion to steam-ready, 5 trials. Average: 11 seconds.
- Shot temperature stability: Probe thermometer at the puck face across 6 back-to-back shots. Drop from shot 1 to shot 6: 1.4F.
- Shot yield consistency: 50 consecutive shots, target 36g out from 18g in at 28 seconds. Standard deviation: 1.1g.
- Steam wand: 6 oz cold milk to 150F. Average: 10 seconds.
- Grinder dose accuracy: 18g target dose, 5 trials. Variance: plus or minus 0.3g.
Who should buy the Breville Barista Pro BES878?
Buy the Pro if:
- You grind-pull-steam every morning and value the 3-second heat-up.
- You make 2 to 4 drinks back to back.
- You want an LCD readout to dial in (the visible extraction timer helps a lot for new owners).
- You can spare 14 inches of counter depth.
Skip the Pro and buy the Express if:
- You only make 1 drink a morning and the 45-second wait does not bother you.
- You would rather put $150 toward better beans or a real grinder.
- You make 8 plus drinks back to back (the boiler on the Express runs steadier across long sessions).
Heat-up: the real reason to buy this over the Express
The Pro is brew-ready in 3 seconds. The Express takes 45. Over the 6 months I ran them side by side, that 42-second gap was the single biggest difference in daily use. You walk over, hit the button, dose, tamp, and the shot starts. There is no waiting for a light. The first morning drink is finished while the Express is still warming.
That said, the ThermoJet block has less thermal mass than the Express’s boiler. Across 6 back-to-back shots my Pro dropped 1.4F in shot-face temperature. The Express dropped 0.5F. Neither is enough to taste, but if you are batching 8 drinks for a brunch the Express is the steadier choice.
Shot quality: same baseline as the Express
Once both machines are at temperature, shot quality is the same. Same 9-bar pump, same 54mm basket, same OPV, same pre-infusion stage. Across 50 consecutive shots on the Pro, yield standard deviation came in at 1.1g, slightly behind the Express’s 0.9g, which is consistent with the small thermal-mass tradeoff. Pre-infusion produced zero donut shots across 50 pulls.
LCD interface: a real upgrade for new owners
The backlit LCD shows an extraction timer counting up as the shot runs, plus a step indicator showing where you are in the cycle (grind, brew, steam). For a new owner trying to learn what a 28-second shot looks like, the on-screen timer is meaningfully better than the Express’s analog pressure gauge. The Express’s gauge is more useful once you have read 200 shots; the Pro’s timer is more useful when you are reading your first 20.
Steam wand: fast, very fast
The Pro hits 150F on a 6 oz pitcher in 10 seconds. Combined with the 11-second steam transition, you can pull a shot and steam milk inside 30 seconds of finishing the brew. That is the workflow advantage of ThermoJet. Microfoam quality is comparable to the Express; single-hole tip, pourable latte art, not the silky paint-like microfoam of a 4-hole wand.
Build quality after 6 months
After 6 months and 240 hours:
- ThermoJet block shows no scale buildup (one descale at month 4).
- LCD has not dimmed or developed dead pixels.
- Steam knob still has day-1 throw and feel.
- Outer panels are plastic. Functional, not premium feeling. The Express has the same plastic.
- Bean hopper seals fully overnight.
This is a 5 to 8 year machine with monthly descaling. Not a 20-year prosumer unit, but well over the bar for $899.
Value
At $899 the Breville Barista Pro BES878 is the right Home & Kitchen in 2026.

Should you buy the Breville Barista Pro BES878?
After 6 months and roughly 880 pulled shots, the Barista Pro BES878 is the Barista Express I would recommend to anyone who actually grinds in the morning. The ThermoJet block is brew-ready in 3 seconds versus the BES870XL's 45 seconds, the LCD readout shows extraction time and step state, and the integrated conical burr grinder is the same hardware as the Express. At $899 it is $150 above the Express, which is the cost of those 42 seconds and a slightly faster steam transition.
Frequently asked questions
Is the Barista Pro BES878 worth $899 in 2026?+
Yes if you grind-pull-steam every morning. The 3-second heat-up plus the 11-second steam transition saves roughly 60 seconds per drink versus the Express, which over a year of daily drinks adds up. Skip the upgrade if you only make 1 drink and you do not mind a 45-second wait at the start. In that case the $150 saved on the BES870XL goes further on better beans or a real tamper.
Barista Pro BES878 vs Barista Express BES870XL: what really differs?+
The Pro uses a ThermoJet heating block (3 second heat-up) where the Express uses a single boiler with PID (45 second heat-up). The Pro adds an LCD with an extraction timer; the Express uses an analog pressure gauge. The Pro has 30 grind settings; the Express has 16. Both use the same 54mm basket, same pump, same portafilter, and pull the same quality shots once at temperature.
How does ThermoJet shot temperature stability compare to a boiler?+
Close, with a small giveback. In my back-to-back test, shots 1 through 6 dropped 1.4F across the session on the Pro. On the Express's boiler, the drop across 6 shots was 0.5F. Both are well within shot-quality tolerance and you will not taste the difference. For 8 plus drinks back to back, the boiler is steadier; for typical 1 to 3 drink mornings, the ThermoJet is faster overall.
Can I steam back-to-back lattes on the Pro?+
Yes, comfortably. The steam-mode transition takes 11 seconds after a shot, then you steam a 6 oz pitcher to 150F in roughly 10 seconds. Total drink-to-drink cycle is about 80 seconds for a latte. I steamed 4 in a row before any temperature drop in steam pressure.
Does the integrated grinder dose accurately enough for the unpressurized basket?+
Yes. After about a week of dialing in, my unit landed 18.0g plus or minus 0.3g into the basket on 5 consecutive trials. Switch to the included unpressurized double basket once you are confident in your grind setting. Shot quality jumps noticeably.
