Match Your Grinder to Your Machine
Your grinder should be at least equal in quality to your espresso machine — and ideally a step above. Pairing a $5,000 La Marzocco with a budget blade grinder is like putting petrol station fuel in a Ferrari. We recommend spending at least 30–40% of your total espresso setup budget on the grinder.
Stepless vs Stepped Adjustment
Stepless grinders allow infinite grind adjustments between settings, giving you maximum precision for dialling in espresso. Stepped grinders have fixed click settings — easier to navigate but less precise. For espresso, stepless is strongly preferred.
Single Dose vs Hopper Grinders
Hopper grinders hold a quantity of beans in a reservoir — convenient for home use if you use the same beans daily, and essential for high-volume cafés. Single-dose grinders grind only what you load for each shot — ideal for home baristas who like to experiment with different beans, as there's no retention or staling between uses.
Burr Size
Larger burrs run cooler (less friction per revolution), produce more even particle distribution, and have higher throughput capacity. For espresso, burrs of 58mm+ are the home standard, while commercial grinders typically use 65mm, 83mm, or 98mm burrs. Larger burrs generally mean better quality — and higher price.
Retention
Retention refers to how much ground coffee stays inside the grinder between uses. High retention = stale grounds mixing with fresh. For home use, look for low-retention designs (under 0.5g). Commercial grinders with dosers typically have higher retention, which is acceptable when volume keeps grounds cycling through quickly.
