Niche Coffee Grinder: Why the Niche Zero Became the Most Hyped Grinder in Coffee

The Niche Zero is a single-dose, conical burr grinder made in the UK that grinds for both espresso and filter coffee with near-zero retention. It costs around $700 to $750 and has become one of the most discussed grinders in the specialty coffee world since its 2019 Kickstarter launch. If you are looking for one grinder that handles everything from espresso to French press without wasting beans, the Niche Zero is the machine that started that whole conversation.

I have used the Niche Zero for over two years across espresso, pour-over, AeroPress, and French press. It does all of them well, which is rare for any grinder at any price. Here is a detailed look at what makes it special, where it falls short, and whether it justifies the price tag. I will also touch on the newer Niche Duo, which takes the concept further. For pricing comparisons with other models, check our roundup of Niche Zero pricing.

What Makes the Niche Zero Different

Most grinders are designed for either espresso or filter, and they compromise when you try to use them outside their intended range. The Niche Zero was designed from the start to be a true all-rounder.

Single-Dose, Zero-Retention Design

The Niche Zero has no hopper. You weigh out your beans, drop them into the top funnel, and grind. The grounds fall directly into a dosing cup that sits on a magnetic base below the chute. When the motor stops, you get back almost exactly what you put in. Retention is typically 0.1 to 0.3 grams, which is as close to zero as any grinder achieves.

This matters for two reasons. First, you do not waste expensive specialty beans to purging. Every gram goes into your cup. Second, you can switch between espresso and filter grind sizes without contaminating your dose with stale retained grounds from the previous setting. Grind espresso in the morning, switch to pour-over in the afternoon, and each cup tastes clean.

The 63mm Conical Burrs

The Niche uses 63mm Mazzer-style conical burrs, which are well-known in the commercial grinder world. These burrs produce a grind profile with good body and sweetness, characteristic of conical geometry. The particle distribution is wider than what you get from premium flat burr grinders, which means espresso from the Niche tends to be full-bodied and smooth rather than bright and complex.

For most people and most beans, this grind profile produces excellent espresso. Light roast single-origin espresso is where the Niche shows its limitation. If you want maximum clarity and separation of flavors in a light roast shot, a flat burr grinder (like the Eureka Mignon Specialita or the DF64) will give you more definition. For medium and dark roasts, milk drinks, and all filter methods, the Niche is outstanding.

Grind Performance Across Methods

I tested the Niche Zero extensively across four brew methods. Here is what I found.

Espresso

The stepless adjustment dial moves smoothly from the finest espresso settings through to the coarsest filter grinds. For espresso, the sweet spot sits in the 10 to 20 range on the numbered dial (the exact number varies by bean). Dialing in a new bag takes 2 to 4 test shots, and once you find your mark, the Niche holds that setting consistently from shot to shot.

Shot quality is rich and creamy with excellent texture. Crema production is good. The conical burrs create espresso with more body and less acidity than flat burr grinders, which works beautifully for traditional espresso drinks and anything with milk.

Pour-Over

Moving the dial to the 40 to 55 range gives you a medium grind for V60, Chemex, and Kalita Wave. The Niche performs well here, though it is not its primary strength. Pour-over cups have good sweetness and body. They are not as precise or clean as what you get from a dedicated filter grinder like the Fellow Ode Gen 2, but the difference is subtle and most people would not notice unless doing a direct side-by-side comparison.

French Press

At 60 to 75 on the dial, the coarse grind is consistent and produces a full-bodied, clean French press. The low fines production at coarse settings means less silt in your cup compared to many grinders at this price.

AeroPress

The Niche handles AeroPress at any setting within its range. I typically use 30 to 40 for a standard AeroPress recipe, and the results are consistently excellent. The AeroPress is forgiving by nature, and the Niche gives it more than enough grind quality to work with.

Build Quality and Aesthetics

The Niche Zero is a good-looking machine. The body is powder-coated aluminum available in white or black, with a wood accent on the top funnel. It weighs about 18 pounds, which keeps it planted during grinding. The footprint is compact at roughly 4 x 8 x 12 inches.

The build quality is solid throughout. The adjustment dial turns smoothly with no play or wobble. The dosing cup is metal with a wood handle that matches the funnel accent. Everything about the Niche feels intentional and well-considered.

One cosmetic note: the white version can show scuff marks over time, especially around the grind chute where the dosing cup contacts the base. The black version hides wear better.

The Workflow

Daily use with the Niche follows a simple pattern:

1. Weigh out your dose (I use 18g for espresso, 15 to 20g for filter)
2. Set the dial to your desired grind setting
3. Pour beans into the top funnel
4. Press the power button
5. Grinding finishes in about 15 to 25 seconds depending on dose and setting
6. Remove the dosing cup
7. Transfer grounds to your portafilter or brewer

The whole process takes under a minute. Switching between espresso and filter is as simple as turning the dial. I mark my preferred settings with a small piece of tape so I can return to them quickly after switching.

Noise Level

The Niche is moderate in volume. It is not as quiet as the Eureka Mignon line, but it is not aggressively loud either. The motor runs smoothly without the high-pitched whine that some flat burr grinders produce. Early morning grinding is feasible without waking the household, especially if your bedroom is a room away from the kitchen.

Price and Value

At $700 to $750, the Niche Zero is not cheap. But consider what you are getting: a single grinder that handles both espresso and filter with near-zero retention and no-waste single dosing. The alternative is buying two separate grinders (one for espresso, one for filter), which easily costs $800 to $1,000+ for comparable quality.

For people who brew both espresso and filter coffee at home, the Niche Zero actually saves money compared to a two-grinder setup. For espresso-only or filter-only users, the value proposition is less clear since you can get comparable single-method performance from cheaper grinders. See our Niche Zero price tracker for current deals and availability.

The Niche Duo

Niche released the Duo in 2024, which uses 83mm flat burrs instead of the Zero's 63mm conical burrs. The Duo produces cleaner, more detailed espresso with better light-roast performance. It costs around $1,000 and is worth considering if flat burr flavor clarity is important to you. The Zero remains the better value at $300 less and still performs excellently for the vast majority of home brewers.

Who Should Buy the Niche Zero

The Niche Zero is ideal for home baristas who brew both espresso and filter coffee and want one grinder to handle everything. It works especially well if you drink medium to dark roast espresso, enjoy milk-based drinks, and want the convenience of zero-waste single dosing.

It also suits people who buy expensive specialty beans and do not want to lose grams to purging and retention. Over a year of daily use, the Zero's near-zero retention saves roughly 500 to 700 grams of coffee compared to a grinder with 2 to 3 grams of retention. At specialty bean prices, that adds up.

Who Should Look Elsewhere

If you only brew filter coffee, a $350 Fellow Ode Gen 2 or a $200 Baratza Virtuoso+ does the job for half the price. If you only brew espresso and want maximum clarity from light roasts, a flat burr grinder like the Eureka Mignon XL or the DF64 outperforms the Niche in that specific area. If your budget is under $500, the Niche is simply out of reach, and there are excellent options at lower price points in our best coffee grinder roundup.

Frequently Asked Questions

Is the Niche Zero good for beginners?

Yes, with a caveat. The grinder itself is straightforward to use. But at $700+, it is a significant investment for someone who is still figuring out whether they enjoy espresso. If you are confident in your commitment to home espresso, it is a grinder you will not outgrow. If you are unsure, start with something in the $200 to $300 range first.

How does the Niche Zero compare to the Eureka Mignon Specialita?

The Specialita ($400 to $500) is espresso-only and uses flat burrs that produce cleaner, more detailed shots, especially with light roasts. The Niche ($700 to $750) does both espresso and filter, uses conical burrs that produce more body and sweetness, and has near-zero retention. If you only brew espresso and prefer clarity, the Specialita wins. If you need versatility, the Niche wins.

Does the Niche Zero require seasoning?

Yes. New burrs benefit from about 2 to 5 pounds of coffee run through them before they reach peak performance. During seasoning, grind quality improves as the burrs wear into their optimal alignment. Some users notice a metallic taste in the first few pounds.

How long do the Niche Zero burrs last?

Niche estimates the 63mm conical burrs will last 40,000+ doses under normal home use. That translates to roughly 10 to 15 years of daily grinding. Replacement burrs cost about $50 to $60.

The Practical Takeaway

The Niche Zero is a versatile, well-built, single-dose grinder that genuinely handles both espresso and filter coffee. It costs more upfront than single-purpose alternatives but replaces two grinders with one. Buy it if you brew multiple methods and want zero waste. Skip it if you only brew one way and can save $300+ with a dedicated grinder for your preferred method.
