Overview
The Niche Duo is the highly anticipated flat burr follow-up to the legendary Niche Zero. Featuring massive 83mm flat burrs in a remarkably compact chassis, the Duo delivers the clarity, sweetness, and complexity that flat burr enthusiasts desire. The dual-function design handles both espresso and filter brewing with a simple switch mechanism, eliminating the need for two grinders. Retention is impressively low at around 0.3g, maintaining the single-dose philosophy that made the Zero famous. The Duo represents Niche continued mission to make high-quality grinding accessible to home baristas, now with the flat burr flavor profile that many advanced users prefer. A strong contender for the best all-around home grinder available.
The Niche Duo features a 83mm flat burr set, crafted from steel. The burrs spin at 1200 RPM, offering fast grinding for high-volume use. Grind retention is approximately 0.3g — virtually zero retention, making it excellent for single dosing.
At $999, the Niche Duo is aimed at dedicated prosumers who demand top-tier grind consistency. Key workflow features include single-dose design (no hopper needed) and stepless grind adjustment for infinite precision. The flat burr design produces a more uniform particle distribution, prized for clarity and sweetness in the cup.

Our Verdict
The Niche Duo uses flat burrs, which are the preferred geometry for espresso among competition baristas and specialty coffee professionals. Flat burrs produce a more unimodal (uniform) particle distribution, which translates to cleaner, sweeter espresso with more clarity than conical alternatives. The mid-range price buys you a grinder that should be the last one most home baristas ever need. Pair it with a machine that does justice to the grind quality, and you'll taste the difference in every shot.
Frequently Asked Questions
Can the Niche Duo grind fine enough for espresso?
Yes, the Niche Duo is capable of grinding fine enough for espresso. Its stepless adjustment allows you to dial in precisely for any coffee.
Is the Niche Duo good for single dosing?
Yes, the Niche Duo is designed for single dosing. With only 0.3g of retention, virtually all the coffee you put in comes out ground. Weigh your beans before grinding for the most consistent results.
Why choose flat burrs in the Niche Duo?
Flat burrs produce a more uniform (unimodal) particle distribution compared to conical burrs. This translates to cleaner, more transparent espresso flavors with pronounced sweetness and clarity. Many competition baristas and specialty roasters prefer flat burr grinders for this reason.
How do I maintain the Niche Duo?
Clean out retained grounds after each use with a brush or bellows. Deep clean the burrs every 2-4 weeks by removing them and brushing away oil buildup. For the motor, occasional use of grinder cleaning tablets (like Grindz) helps remove coffee oil buildup. Never wash burrs with water.
Is the Niche Duo worth $999?
The grinder is the most important variable in espresso quality — more important than the machine. Investing in a quality grinder like the Niche Duo will have a bigger impact on your espresso than upgrading any other piece of equipment. If you're serious about espresso, this level of grinder investment is justified.
