Niche Zero
Niche · Grinder
When the Niche Zero reached consumers, it solved a problem that home espresso enthusiasts had been working around for years: the retention penalty of hopper-fed grinders. Most grinders designed for espresso keep several grams of coffee trapped in the grind path between doses — stale grounds that contaminate the next shot and make dose-to-dose consistency nearly impossible without purging waste. The Niche Zero was engineered from the first principles of single-dose grinding: beans enter the top, grounds exit into a waiting portafilter or cup, and virtually nothing remains behind. Measured retention is consistently reported under 0.1 g by independent reviewers — an industry-leading figure at any price.
Burr set: 63mm conical steel burrs, a geometry chosen deliberately over flat burrs to reduce static and improve single-dose workflow without the temperature sensitivity that can affect large flat-burr sets. The conical profile also contributes to the Zero's relatively forgiving grind-size range: it covers filter through espresso on a single stepless dial, though its sweet spot and primary reputation sit firmly in espresso.
Footprint and build: The Zero is tall and narrow — roughly 125mm wide — making it genuinely counter-friendly in small kitchens. The exterior is a single cast zinc body available in white or black. The motor is relatively quiet by espresso-grinder standards.
Who it's for: The home barista pulling one to four espresso-based drinks per day who wants repeatable, near-zero-waste single-dose grinding and is willing to pay a premium for it. At $620–$750, it is a significant investment, not an impulse purchase.
Honest caveat: The Niche Zero is not a speed demon. Its conical burrs grind more slowly than comparable flat-burr machines, and high-volume users will notice. It is also primarily an espresso grinder; while it can handle filter, dedicated flat-burr filter grinders at lower price points will outperform it on very coarse, open settings.
