Electric milling of teeth

An electric milling of teeth does the same thing as a manual, but with a motor. There are two types of teeth: conics, which usually give more body, and flat ones, which give a more uniform milling and clearer cups. Both serve; the differences are of nuance.

The models for everything, from filter to basic espresso, have many adjustment steps. The single-dose ones do not keep coffee in the hopper: you weigh the grain, throw it out and grind it whole, so it's always fresh.

• Please: fast, comfortable and constant.
• In favour: ideal if you prepare several cups a day.
• Against: more expensive, noisy and bulky than a manual.
• Against: it retains some coffee inside; it cleans it often.

Guidance prices: Baratza Encore ESP, €150-200; Eureka Mignon, €300-600; DF64 or Niche, €350-700. See that the milling range covers your method, how much coffee it retains and how easy it is to remove the teeth to clean them.

Cheapest alternative: a manual milling mill (€60-300) gives the same quality in exchange for your arm.
