The Niche Zero did not invent single-dose grinding, but it made the concept accessible, practical, and desirable for home coffee enthusiasts in a way that no previous product had managed. Before the Niche, the standard home grinder workflow involved a hopper full of beans, timer-based dosing, and inevitable retention — stale grounds trapped in the grinding chamber from the previous session contaminating today’s coffee. The Niche proposed a different approach: weigh your dose, drop it in, grind it all, get it all out. Zero retention. The name is the promise.
Kickstarter Origins and Market Impact
The Niche Zero launched on Kickstarter in 2018 and delivered to backers in 2019, entering a market where home grinders generally fell into two categories: hopper-fed consumer machines from Baratza and similar brands, or miniaturized commercial grinders adapted (often poorly) for home use. The Niche was designed from the ground up as a home single-dose grinder, and this focus showed in every design decision.
The Kickstarter campaign raised over one million pounds, reflecting pent-up demand from a home coffee community that had been discussing single-dose grinding on forums for years without having a purpose-built option to buy. Early reviews were overwhelmingly positive, and the Niche rapidly became one of the most recommended grinders in online coffee communities. Demand consistently exceeded supply for the first several years of production, creating waitlists and secondary-market premiums that have only recently stabilized.
The Niche’s market impact extended beyond its own sales. It demonstrated that home coffee enthusiasts would pay a premium for single-dose workflow, inspiring competitors to release their own single-dose designs. The DF64, Fellow Ode, and numerous other grinders that followed owe their market positioning at least partially to the demand the Niche revealed.
The 63mm Conical Burr Set
The Niche uses a 63mm conical burr set sourced from Mazzer, the Italian commercial grinder manufacturer. These are not consumer-grade components — the same burr family appears in Mazzer’s commercial grinder lineup, and the size places them firmly in the prosumer category. For context, the Baratza Encore uses 40mm conical burrs, and the Comandante C40 hand grinder uses 39mm conicals. The Niche’s 63mm burrs provide substantially more cutting surface, which translates to faster grinding and the thermal mass to maintain consistent temperature during a dose.
The conical burr geometry produces a bimodal particle distribution — a primary peak of target-size particles alongside a smaller population of fine particles. This is characteristic of all conical burrs and is not unique to the Niche. The practical effect in the cup is a full-bodied, well-rounded brew with good sweetness and moderate clarity. The Niche will not produce the laser-sharp flavor separation of a premium flat burr grinder, but it produces a cup profile that the majority of home brewers find deeply satisfying.
Grinding speed for a typical 18-gram dose is approximately 10 to 15 seconds, which is fast enough that the grinder never feels like it is delaying your morning routine. The motor runs at a relatively low RPM compared to commercial grinders, which reduces noise and heat generation — both meaningful quality-of-life improvements in a home kitchen context.
Zero Retention Design
The grinder’s namesake feature is its near-zero retention. The vertical burr orientation and a swept grinding path mean that gravity pulls grounds down and out of the burr chamber into the dosing cup below. After a dose, the Niche typically retains 0.1 to 0.3 grams — low enough that switching between coffee beans does not produce noticeable flavor contamination.
This matters for two interrelated reasons. First, it means every gram you put in comes out, so your dose weight is accurate without compensation. If you weigh 18 grams of beans and drop them in, you get approximately 18 grams of ground coffee in your portafilter or brewer. Second, and more importantly for home users who often have multiple bags open, it means you can switch between an Ethiopian light roast and a Brazilian medium roast between brews without the first coffee ghosting into the second.
The included dosing cup sits below the grinding outlet and catches grounds with minimal mess. The cup is designed to fit common portafilter sizes for espresso users, and pour-over brewers can grind directly into their brewer or a separate container.
The Home All-Rounder Proposition
The Niche positions itself as a grinder that handles everything from espresso to French press. The stepless adjustment mechanism covers the full range, and the 63mm conical burrs perform respectably at both ends of the spectrum. This all-rounder proposition is the Niche’s primary value argument: instead of buying a dedicated espresso grinder and a dedicated brew grinder, buy one Niche.
For espresso, the Niche performs well. The stepless adjustment provides the fine resolution that espresso demands, and the grind consistency is sufficient for excellent shots on home machines. Professional baristas and advanced home users note that the conical burr profile produces espresso with more body and less clarity than flat burr alternatives — a legitimate preference distinction rather than a quality hierarchy.
For filter brewing, the Niche is competent but not exceptional. At coarser settings, the bimodal distribution characteristic of conical burrs becomes more pronounced, producing a wider spread of particle sizes than a dedicated filter grinder with flat burrs would achieve. The resulting pour-over is good — significantly better than a Baratza Encore and comparable to many $300-range dedicated filter grinders — but it does not match the clarity and flavor definition of a Fellow Ode Gen 2 or a DF64 with aftermarket flat burrs.
The honest assessment is that the Niche is an excellent espresso grinder that is also a good filter grinder. If espresso is your primary use case with occasional pour-over, the Niche is ideal. If pour-over is your primary use case, dedicated flat burr options may serve you better.
Workflow and Daily Use
The Niche’s workflow is its most underappreciated feature. The absence of a hopper means you engage with your beans every session — weighing a dose, selecting from your current collection, and committing to a specific coffee for this brew. This sounds trivial but represents a meaningful shift from the hopper-fed approach where you load 250 grams and grind through them over several days. Single-dosing encourages fresher beans (no extended hopper exposure to air and light) and more intentional brewing.
The grinder is compact — smaller than most competitors with equivalent burr sizes — and the low-profile design fits under standard kitchen cabinets. Noise levels are moderate; the Niche is quieter than most flat burr grinders and comparable to other conical designs. It will not wake a sleeping household if you grind at reasonable hours, though early-morning use in a studio apartment might test a partner’s patience.
Cleanup is simple. The removable upper burr lifts out for brushing, and the grinding chamber can be cleared with the included brush. Monthly deep cleaning takes under five minutes.
Compared to Alternatives
Against the Fellow Ode Gen 2, the Niche offers espresso capability that the Ode explicitly lacks, plus conical burr character that some brewers prefer. The Ode counters with superior flat-burr clarity for pour-over. If you only brew filter coffee, the Ode is likely the better dedicated choice. If you want one grinder for everything, the Niche wins.
Against the DF64 with aftermarket burrs, the Niche offers a more refined out-of-box experience with better build quality and zero-retention workflow. The DF64 counters with flat burr clarity and an upgrade path through aftermarket burr sets. The DF64 requires more setup and tinkering to reach its potential; the Niche delivers its full capability from unboxing.
Against the Baratza Vario, the Niche offers better build quality, quieter operation, and true zero-retention single-dosing. The Vario counters with Baratza’s legendary repairability and parts availability. Both occupy similar price points; the Niche is generally considered the superior product unless Baratza’s serviceability philosophy is a priority.
Practical Tips
When switching between espresso and filter settings, mark your preferred positions with tape or a paint marker on the adjustment collar. The stepless mechanism means returning to an exact position requires either visual reference or careful counting of rotations. Some users keep a small notebook of settings for different coffees and methods.
For best results with light-roast pour-over, grind slightly finer than you might on a flat burr grinder. The bimodal distribution means your effective extraction rate is lower than the average particle size suggests, and compensating with a finer setting improves the balance.
Use the Niche’s dosing cup for espresso and grind directly into your pour-over brewer or server for filter coffee. The dosing cup works well for espresso workflow but adds an unnecessary transfer step for pour-over.
