The differences that matter
- Single dose, 50 g hopper → 300 g hopper: the DF64 is reloaded for every dose, the Libra is filled once
- Espresso, pour over and French press → espresso only: with the Libra, other methods mean a second grinder
- 110 V → 220 V: the DF64 is listed at 110 V, so check it against a 220 V supply before buying
- 30 cm → 39 cm tall: the DF64 fits under a lower shelf
Which one to choose
Choose DF64 Gen 2 if…
You change coffees often, say an espresso and then a pour over in the same weekend: you grind only the dose you need, and the DF64 also covers pour over and French press, with 64 mm burrs. It is 30 cm tall against 39. The trade-off: the 50 g hopper means reloading for every grind, and it is listed at 110 V while the Libra is 220 V, so check compatibility with your mains.
Choose Mignon Libra if…
Several espressos in a row with the same coffee: the 300 g hopper is filled once and does not need reloading for each dose. In return it is not single dose, lists espresso only and pour over or French press need another grinder. It is 39 cm tall and runs at 220 V.
