Breville Smart Grinder Pro (BCG820)

The Smart Grinder Pro is the grinder for the kitchen where an espresso machine and a drip brewer share a counter and a bag of beans. Fill the hopper, set one preset for a double shot and another for a six-cup pot, and switch between them by turning the dial and pressing a button. That is why it is the pick for switching between espresso and drip on our list of the best espresso grinders under $300, and why TechGearLab made it the editors' choice in its grinder guide updated June 2, 2025. Coffeeness reached the same conclusion from the other direction and called it the best budget espresso grinder.

It is also the natural partner for a Breville espresso machine. The small cradle fits 50 to 54 mm portafilters, the size Breville's own machines use, and grinding straight into the basket with a timed dose is the workflow those machines assume.

Control. Sixty settings run from very fine to press-coarse, and Breville lets you reposition the upper burr to move the whole range, so if setting 1 is still too coarse for your machine you can shift everything finer. Coffeeness found the espresso sweet spot between 9 and 11 on the dial with the standard burr position, which leaves room in both directions.

Dosing. The timer runs in 0.2-second steps, and the LCD shows grind setting, time and the number of shots or cups. You can pause mid-grind, which TechGearLab found useful for topping up a basket. Coffeeness measured throughput at about 2 g per second, so a 0.2 s step is roughly 0.4 g of coffee, fine enough to land a dose within a gram once the hopper level is steady.

Consistency. TechGearLab scored it 85 out of 100 and first of the 16 grinders in its test, with 9.4 for ease of use, 8.7 for cleanliness and 7.8 for grind consistency. At espresso settings it produced extraction times the site described as very consistent and close to ideal. Coffeeness found the espresso grounds uniform with minimal clumping, and both sources noted low static: grounds fall into the container or portafilter rather than clinging to it.

Practicalities. The cradles attach magnetically, a switch beneath the chute starts the grind when the portafilter is pushed in, the 12 oz grounds container has a lid, and the housing is stainless steel. Whole Latte Love lists a 165 W motor and a one-year limited warranty, in brushed stainless, black truffle and damson blue. Cleaning, per Coffeeness, is a weekly brush of the burrs after lifting out the upper burr.

Coarse grinds are the known weakness. TechGearLab's consistency score was dragged down by the amount of dust-fine particles at French press and cold brew settings; repositioning the upper burr roughly halved the fines but did not remove them. Coffeeness reached the same conclusion. If press or cold brew is your main method, this is the wrong grinder.

Timed dosing is not weighed dosing. A timer delivers a consistent amount only while the hopper level, bean density and grind setting stay the same. Change the roast or let the hopper run low and the dose drifts. Coffeeness noted that no weight-based mode exists; a scale under the portafilter is the practical fix.

It is tall. At 15.3 in with the hopper on, it will not sit under every cabinet, and Coffeeness flagged this as the first thing to measure.

Retention is middling. TechGearLab found clean pours and little static, and Coffeeness saw no chute problems in its test, but the reviewer relayed owner complaints of grounds packing in the chute. A hopper grinder that holds some coffee between doses is normal; it is just not the near-zero retention of the Sette 30 or DF54.

Two smaller points. The grounds container opening is slightly undersized, TechGearLab noted, so grounds spill unless the lid is off. And Coffeeness found the cradles a tight fit, which needs care when swapping them.

The Baratza Encore ESP is the other budget option. Coffeeness preferred the Breville's portafilter-friendly design, and CoffeeGeek preferred the Encore ESP's espresso output while conceding the Breville is quieter, has a timer and grinds better for press pot; the Baratza has the stronger parts and repair support.

The Baratza Sette 30 is louder, faster and almost retention-free, with a portafilter holder of its own, but it has half the settings and is a poorer match for filter coffee.

The DF54 is the grind-quality choice: flat burrs, stepless adjustment, single dosing and bellows. It has no hopper, no timer and no cradle, and it takes several times longer per dose. Pick the DF54 if you weigh every dose and taste the difference; pick the Breville if you want to press a button.

The Smart Grinder Pro earns its place by being the easiest grinder in the class to live with when espresso and drip alternate through the week. Its espresso is good, its coarse grinds are not, and its dose is only as consistent as your hopper level. For a Breville owner who wants a matching, automated workflow it is the obvious buy; for the best shot in the class, the DF54 is.
