The Niche Zero and Niche Duo are the same single-dosing philosophy with different burr geometry: the Zero runs 63mm conical burrs and made its name as the espresso single-doser; the Duo runs 83mm flat burrs with swappable sets, aimed at people who want conical body for espresso one day and flat-burr clarity for filter the next. The Zero is the simpler, cheaper, proven pick for espresso-first homes. The Duo is for the drinker who genuinely brews both styles and wants one grinder to serve two masters.

What the Zero got famous for still holds
Single dosing with almost nothing retained in the burrs means the dose you weigh is the dose you brew, bean swaps are instant, and yesterday's stale grounds never contaminate today's shot. The 63mm conicals produce the dense, traditional espresso texture most home baristas are chasing, and the workflow is so simple it has no learning curve: fill, grind, done. For a one-style espresso home, spending up on the Duo buys capability that never gets used.
What the Duo actually adds
Flat burrs separate flavors that conicals blend, which shows up as clarity in filter brews and a different, some say brighter, espresso profile. The Duo's party trick is the swappable burr sets: an espresso-leaning set and a filter-leaning set in one body, changed in minutes. That is real value only for the household that brews V60 in the morning and pulls shots after dinner; it is a burr library, and libraries only pay off if you visit. Pair either with the technique pages: pour over for the flat-burr mornings, the dial-in cheat sheet for the shots.
The honest budget note
Both Niches cost more than most machines they feed. If the grinder budget is under $300, the value tier delivers most of the result: our under-$300 espresso grinder guide and the zero-retention roundup cover the field the Niche sits atop. Single dosing is a workflow, not a price bracket, and the DF54 crowd proves it.

FAQ
Is the Niche Duo worth it over the Zero? Only if you genuinely brew both espresso and filter and will use the swappable burr sets. Espresso-only homes get everything the brand does well in the cheaper Zero.
Are the Niche Zero's burrs conical or flat? 63mm conical, which is where its traditional dense espresso character comes from. The Duo's 83mm flats trade body for clarity.
Do Niche grinders really have zero retention? Near-zero: single-dose design keeps leftover grounds to a few tenths of a gram, which is why weighed-in equals weighed-out.
