Niche Zero
  • +Zero retention, by the maker's description, so the coffee you weigh in is the coffee you get out.
  • +63 mm conical burrs with an infinite stepless dial that moves between espresso and filter in seconds.
  • +Dose consistency the maker puts at less than plus or minus 0.2 g.
  • +72 dB while grinding, with an aluminium body and real oak trim.
  • +Compact at 122 mm wide.
  • −Priced in pounds from the UK, so the cost in other countries depends on conversion, shipping and import charges.
  • −No hopper to speak of: every dose is weighed and added by hand, which is the point but not for everyone.
  • −311 mm tall, rising to 435 mm with the lid up, so check the space under wall cabinets.
  • −Niche does not publish burr material, motor power or warranty on the product page.
