How single dosing works on the DF64
Instead of a large hopper, the DF64 takes one weighed dose at a time. The beans land on an anti-popcorn disc, which stops them jumping back out and helps them feed into the burrs faster. On the way out, the ground coffee passes a plasma generator in the exit chute that reduces static, so less coffee clings to the chute and the cup. A few presses on the bellows then clear what is left in the grinding chamber.
The upper burr carrier sits on three seating points with a wave spring, which keeps the burrs stable. The top unscrews by hand, so you can reach the burrs for cleaning without tools.
DF64 or DF54?
The DF54 is the smaller, cheaper sibling built on the same design. Both are stepless single dosers that handle espresso and filter, so the choice comes down to how you brew. The DF64 grinds faster, holds a bigger dose, and its 64 mm burrs can be swapped for aftermarket sets such as the SSP 64mm Multi Purpose burrs if you want to change the flavour profile later. The DF54 makes more sense if you mostly make one or two coffees a day and want a smaller grinder on the counter.

Excellent single dose grinder. Very stable, efficient with minimal to nonexistent grounds retention. Easy to adjust and use and looks great!

Works super well. Heavy, sturdy albeit a bit louder than expected. Very happy with it.

This is my first proper grinder, used for espresso beans only. It’s very sturdy and loads of adjustment options. Easy to clean. A bit noisy, but a single dose is done in a few seconds 🤓☕️

I am pretty satisfied with the Gen 2. There are no retention issues, it feels solid, and it has delivered great tasting espresso. Unfortunately, the burrs weren’t perfectly aligned from the factory, so I’m currently trying to adjust them manually, which lowers my rating.
