Niche Zero: A Deep Look at the Most Popular Home Espresso Grinder
The Niche Zero is a single-dose conical burr coffee grinder designed in the UK that became the default recommendation in the home espresso community almost overnight when it launched. It uses 63mm Mazzer conical burrs, a stepless adjustment dial, and a unique design where you load exactly one dose of beans per grind. It retains less than 0.2 grams of coffee between doses, which was nearly unheard of when it first shipped. At around $600-700 (depending on the retailer and color), it sits in the sweet spot between entry-level electric grinders and prosumer flat burr machines.
I've followed the Niche Zero since its original Indiegogo campaign, and I've used one extensively for both espresso and filter coffee. It earned its reputation for good reasons, but it also has real limitations that get glossed over in the hype. Here's an honest breakdown of what the Niche Zero does well, where it falls short, and who should (and shouldn't) buy one.
What Makes the Niche Zero Different
Single-Dose Design
Most traditional grinders use a hopper that holds 200-400 grams of beans. You fill it up and the grinder feeds beans automatically. The problem: those beans sit exposed to air, going stale over days.
The Niche Zero has a small cup on top that holds exactly one dose (18-20 grams for espresso, up to 40-50 grams for filter). You weigh your beans, drop them in, and grind. Nothing sits in a hopper going stale. You can switch between different beans every single shot without wasting anything.
This single-dose approach was unusual for electric grinders when the Niche launched. Now it's become a standard design philosophy, with competitors like the DF64, Eureka Single Dose, and others following suit.
Near-Zero Retention
The "Zero" in Niche Zero refers to retention. The grind path is short and steep, and grounds fall directly into a dosing cup below. The design uses gravity rather than pushing grounds through a long horizontal chute. In practice, retention is typically 0.1-0.2 grams, which is negligible for espresso dosing.
Compare this to hopper grinders like the older Eureka Mignon series, which could retain 2-5 grams. That meant your first dose of the day included stale grounds from yesterday, and your dose weight varied unpredictably.
The 63mm Mazzer Burrs
Niche uses 63mm conical burrs manufactured by Mazzer, an Italian company with decades of commercial grinder experience. These are the same burr geometry found in some Mazzer commercial models. They produce a bimodal particle distribution (two peaks), which creates espresso with more body, sweetness, and a syrupy texture compared to the cleaner, brighter shots from flat burr grinders.
For milk drinks, this is a genuine advantage. The body and sweetness cut through steamed milk beautifully. For black espresso drinkers who want bright acidity and distinct tasting notes, flat burr grinders like the Lagom P64 or DF64 with SSP burrs will give you more clarity.
Performance Across Brew Methods
Espresso
This is where the Niche Zero shines. The stepless adjustment dial is smooth and precise, letting you make the tiny changes that espresso demands. The grind consistency is excellent for a conical burr grinder, producing balanced, sweet shots with good body.
Dialing in is straightforward. The numbered dial goes from 0 (finest) to 50 (coarsest), and espresso typically falls between 8 and 18 depending on the beans. The numbers are printed clearly and the dial stays put once you set it.
For people pulling 1-4 shots per day, the Niche Zero is a near-perfect espresso grinder. It's fast enough (about 15 seconds for an 18-gram dose), quiet by electric grinder standards, and produces consistently good shots.
Filter Coffee (Pour-Over, French Press)
The Niche Zero works for filter coffee, but this is where opinions split. Some people find the bimodal conical burr distribution produces a heavier, sweeter pour-over that they enjoy. Others find it muddier and less defined than what a flat burr grinder produces.
For French press, the Niche does well. The coarse grind range is adequate, and the body-forward character of conical burrs complements immersion brewing.
For V60 and Chemex pour-over, the Niche is decent but not outstanding. If filter coffee is your primary brew method, a flat burr grinder like the Fellow Ode or Eureka Mignon with filter burrs will give you a cleaner cup with more clarity.
The Niche Zero works as a do-everything grinder, but it's at its best making espresso.
Switching Between Espresso and Filter
This is one of the Niche's strong selling points. Because it's single-dose with near-zero retention, you can grind an espresso dose at setting 12, immediately change the dial to setting 30 for pour-over, and grind without wasting any coffee. With a hopper grinder, switching means purging 5-10 grams of transitional grounds every time.
The dial is easy to read and return to previous positions. Some owners mark their preferred settings with tape or a marker for quick reference.
Build Quality and Design
The Niche Zero is built solidly. The body is mostly aluminum, the base is heavy enough to stay planted during grinding, and the fit and finish feel premium. It comes in white, black, and a few limited-edition colors. The footprint is small (about 4 inches by 4 inches) which is a real benefit on crowded counters.
The dosing cup that catches grounds is included and made of stainless steel. It's designed to sit under the grind chute and then be placed directly on your portafilter for transfer. The workflow is clean: weigh beans, grind into cup, transfer to portafilter, distribute, tamp, brew.
The power cord is attached (not removable), which is a minor annoyance if you store the grinder in a cabinet between uses. The power switch is on the back, and the grind button is on the front.
One design quirk: the lid on top is lightweight plastic and doesn't seal. Beans can pop out during grinding if you overfill the cup. Not a big deal, but worth noting.
Common Criticisms
Not the best for light roasts. Light-roasted espresso is notoriously hard to grind, requiring very fine settings and extra torque. The Niche handles medium and dark roasts without issue, but some users report that very light roasts produce a slightly wider particle distribution than competitive flat burr grinders.
Bimodal distribution. If you've read enough coffee forums, you've seen the "unimodal vs. Bimodal" debate. The Niche's conical burrs produce bimodal output, which is objectively less uniform than unimodal flat burrs. Whether this is a problem depends entirely on your taste preferences. Many people prefer the sweeter, fuller shots from conical burrs.
Price increases. The Niche launched at around $500 via Indiegogo. Retail price has crept up to $600-700. At that price, it faces stiffer competition from flat burr options like the DF64 ($450-500) and the Eureka Mignon Specialita ($500).
Availability. The Niche Zero has historically been difficult to buy. Production batches sell out quickly, and some colors have waiting lists. This has improved somewhat, but it's not a walk-into-a-store purchase.

Niche Zero vs. The Competition
Niche Zero vs. DF64
The DF64 (also called the Turin DF64 or G-IOTA DF64) uses 64mm flat burrs and costs $400-500. It produces cleaner, more clarity-focused espresso. The Niche produces sweeter, fuller-bodied shots. The DF64 has an edge for light-roast espresso and pour-over. The Niche has a better build quality and simpler workflow. Both are single-dose with low retention.
Niche Zero vs. Eureka Mignon Specialita
The Specialita is a hopper grinder with 55mm flat burrs at around $500. It's more compact, quieter, and has a timed dosing touchscreen. It produces cleaner espresso. But it's not designed for single-dosing (though many people convert it), and retention is higher (1-2 grams stock). The Niche is better for people who switch beans frequently.
Niche Zero vs. Baratza Sette 270
The Sette 270 costs about $300 and uses an unusual conical burr design where the outer ring rotates. It's fast and has good adjustment precision. But it's louder, has a reputation for gear wear, and retains more grounds. The Niche is the better long-term investment at nearly double the price.
Who Should Buy a Niche Zero
- Home espresso brewers pulling 1-4 shots per day
- People who switch between different beans regularly
- Anyone who wants a single grinder for both espresso and occasional filter
- People who value a quiet, compact, low-maintenance grinder
- Milk drink enthusiasts (lattes, cappuccinos, cortados)
Who Should Look Elsewhere
- Dedicated filter/pour-over drinkers (get a flat burr grinder instead)
- Light-roast espresso enthusiasts who want maximum clarity
- Budget-conscious buyers (the DF64 offers comparable value for $150 less)
- People who need to grind for large batches (the single-dose workflow is per-cup)
Frequently Asked Questions
Is the Niche Zero good for pour-over?
It's acceptable, not outstanding. The conical burrs produce a heavier, less transparent pour-over than flat burr grinders. If pour-over is your main brew method, a Fellow Ode or Eureka with filter burrs is a better fit. If espresso is primary and you occasionally make pour-over, the Niche handles both.
How loud is the Niche Zero?
Noticeably quieter than most electric grinders. It produces about 70 decibels during grinding, which is roughly the volume of a conversation. Grinding an espresso dose takes about 15 seconds. You can use it at 6am without waking the whole house, though it's not silent.
Does the Niche Zero need modifications?
No. It works great out of the box. Some owners add a WDT tool (a distribution tool with thin needles) to break up clumps before tamping, but that's a technique tool, not a grinder modification. The Niche doesn't need bellows, anti-popcorn lids, or other aftermarket fixes that some grinders require.
Can I buy a Niche Zero on Amazon?
The Niche Zero is primarily sold through the manufacturer's website (nichecoffee.co.uk) and select retailers. It occasionally appears on Amazon from third-party sellers, but prices are often marked up. Buying direct from Niche is usually the best option for price and warranty coverage.
The Verdict
The Niche Zero earned its reputation. For home espresso, it delivers excellent grind quality with near-zero retention in a compact, quiet, well-built package. It's not the absolute best at any single thing, but it's very good at everything a home barista needs. If you drink primarily espresso with some filter brewing on the side, the Niche Zero is a smart buy that you'll be happy with for years. If pour-over is your main focus or you want the cleanest possible light-roast espresso, look at flat burr alternatives instead.
