Single-Dose Espresso Grinder
DF64 Coffee Grinder
✓ Buy
Among the best in its category
A 64mm flat-burr grinder that punches well above its $350-500 price tag, delivering clarity and speed that light-roast espresso drinkers will love. The adjustment dial binds when you dial fine, it's louder than premium machines, and if you're pulling traditional dark-roast shots chasing body and sweetness, a conical burr grinder will serve you better. Best for tinkerers who value grind quality and upgradability over plug-and-play convenience, and who won't mind a little noise for fluffy, clump-free grounds in under 8 seconds.
The generation that matters
This product isn't one story — here's how each era is regarded.
DF64 Gen 1
2021, 2023
Compromised
Original version had documented design flaws including inconsistent burr alignment, retention issues, and quality control problems. It required tinkering and alignment fixes out of the box.
DF64 Gen 2 / Gen 2.5
2023, present
Strong
Gen 2 addressed many Gen 1 flaws with improved alignment, better build quality, and reduced retention. Users consistently praise grind quality, value, and workflow improvements. Noise remains a common complaint but performance is well-regarded.
