If you're spending £450-550 on a single-dose espresso grinder in 2026, you're choosing between these two. The Niche Zero and the Eureka Mignon Oro Single Dose Pro are both excellent, both near-zero retention, and both designed for the weigh-in, grind, weigh-out workflow that serious home baristas swear by.
But they produce different coffee. And that's the thing nobody tells you when they say "just get a Niche."
The Niche Zero uses 63mm conical burrs. Conical burrs produce a bimodal particle distribution — a mix of fine and coarse particles — which translates to a fuller body, more texture, and a chocolatey, rounded flavour profile. Light roasts get sweetness. Dark roasts get richness. Everything gets body.
The Eureka Oro uses 65mm flat burrs. Flat burrs produce a more uniform particle distribution, which translates to clarity, brightness, and defined origin characteristics. You taste the blueberry in your Ethiopian. You taste the citrus in your Kenyan. The cup is cleaner, brighter, and more transparent.
Neither profile is better. They're different. And your preference probably correlates with how you drink your coffee.
The Niche's full body and chocolatey texture cut through milk beautifully. A flat white made with Niche-ground espresso tastes rich and integrated. The same flat white made with Eureka-ground espresso can taste thinner — the clarity that's a virtue in a straight shot becomes a weakness when you add 150ml of steamed milk.
If you like a thick, syrupy shot with caramel sweetness — the kind of espresso that coats your palate — the Niche is your grinder. If you like a clean, bright shot where you can taste individual flavour notes and origin characteristics, the Eureka is your grinder.
If you mostly drink medium-dark roasts from traditional Italian-style roasters, the Niche will make you happier. If you're buying light-roasted single-origin beans from specialty roasters, the Eureka will show you more of what you're paying for.
The Niche is UK-designed, with a beautiful curved body, a wooden base, and a satisfying grind-cup-on-magnet workflow. It's the kind of object you want visible on your counter. The adjustment dial is stepless and intuitive. It grinds ~10 seconds per 18g dose.
The Eureka is Italian-made, with the Mignon family's compact rectangular design and Eureka's trademark silent operation (~60dB). The 15° angled grinding chamber uses gravity to minimise retention. The blow-up cleaning system purges grounds between doses. It grinds faster — ~7 seconds per 18g — thanks to the larger burrs.
Both retain almost nothing. Both are built to last years. Both are quiet enough for early mornings.
Niche Zero for body, sweetness, milk drinks, and design beauty. Eureka Oro Single Dose Pro for clarity, brightness, black espresso, and light roasts. There is no wrong answer here — only the answer that matches how you drink.
