What is the Niche Zero?
A grinder built around one idea: every gram you put in comes out, and nothing is left behind for the next cup.
The Niche Zero is an electric conical burr grinder designed for single dosing. You weigh the beans for one brew, pour them in, grind, and the chamber empties completely. It uses 63 mm conical burrs and an infinite stepless dial, and Niche describes its straight-through design as zero retention. Niche sells it from its UK website at £559.00.

Single dosing, and why retention matters
Most grinders keep a little coffee behind in the burrs and the chute. That old coffee comes out in your next dose, stale and at the previous grind setting. For someone who switches between an espresso and a filter coffee, or between two different beans in a day, retention means every change starts with a contaminated cup.
The Niche Zero's design addresses that directly. With next to nothing retained, you can weigh 18 g in and get 18 g out, which matters when your recipe is built on weight. The maker also states dose consistency of less than plus or minus 0.2 g and a grind speed of about 1 g per second. Why weighing matters in the first place is set out in brewing by weight.
Burrs and the stepless dial
Sixty-three millimetre conical burrs are large for a home grinder, and larger burrs generally grind faster and more evenly. Conical burrs are also often described as giving espresso a rounder, heavier body than flat burrs, though burr design and alignment matter as much as shape.
The dial is stepless, so there are no fixed clicks: you can make the very small adjustments espresso often needs, then turn to a much coarser setting for filter in a few seconds. That range is what makes the Zero a grinder for people with more than one brewer. The settings each method needs are set out in the grind size guide.
Buying one from the UK
Niche sells the Zero from its own website, priced in pounds. For buyers outside the UK the price shown is only part of the cost: currency conversion, shipping and any import charges all apply, and they change over time. Check the total at checkout before comparing it with grinders sold locally, and make sure you choose the plug type for your country.
Living with it
- Noise. 72 dB while grinding, according to Niche.
- Size. 122 x 211 x 311 mm, and 435 mm tall with the lid up.
- Weight. 4.1 kg.
- Finish. Aluminium with real oak trim, in white or black.
The workflow is slower than a hopper grinder, because every dose is weighed and added by hand. For one or two careful brews a day that is no burden. For a household grinding several cups every morning, it becomes a chore.
What to pair it with
Single dosing only works if you weigh the beans, so a scale reading to a tenth of a gram is not optional with the Niche Zero. It is the natural partner for an espresso machine with an unpressurised 58 mm basket, where small grind changes show up clearly in the shot, and for a pour over or AeroPress on the filter side. Freshly roasted beans bought in small bags suit the single-dose habit, because you are no longer leaving a hopper of beans exposed to air for days. How to keep them fresh between doses is covered in how to store coffee beans.
Niche Zero vs Baratza Sette 270Wi
The Baratza Sette 270Wi, at $599.95 on this site, solves the same problem differently. It keeps a 300 g hopper and doses by weight with a built-in scale, so you set a target and it grinds to it. Its burrs are smaller, 40 mm conical, and it offers 270 stepped settings.
The Sette suits someone who wants hands-off, weighed doses from a hopper, mostly for espresso. The Niche Zero suits someone who single doses, switches coffees and moves between espresso and filter, and wants no retention between them. For a flat burr single-dose alternative on this site, see the DF64 Gen 2.
Is the Niche Zero worth it?
For its intended buyer, yes. A grinder with large conical burrs, a stepless dial and near-zero retention is exactly what someone weighing single doses for espresso and filter needs, and it pairs well with a capable espresso machine such as the Lelit Mara X V2. For anyone who grinds a full hopper for several people, or who only makes one kind of coffee, a hopper grinder does the job with less effort and often for less money once shipping is counted.
Who should buy the Niche Zero (and who should not)
Buy it if
- You weigh every dose and want exactly that weight out of the grinder.
- You switch between beans, or between espresso and filter, during the week.
- You value a quiet, compact grinder on the counter.
Skip it if
- You want to fill a hopper and grind on demand for a family.
- You live outside the UK and shipping and import costs push it past local alternatives.
- You want every specification, including warranty and motor power, published up front.
