Niche Zero: assess the single-dose workflow, not the name alone

The source describes the Niche Zero as a conical-burr grinder with 63 mm steel burrs and approximately 50 grams of capacity. Those specifications provide a starting point, but the exact current model and manufacturer's information should be checked before purchase.

The source writer praises compactness, sound and handling. These remain that reviewer's observations, not BeanScene measurements. Similarly, zero retention in a product name should not be treated as a verified claim that no coffee can remain in the grinder under every condition.

For a useful comparison, consider your normal dose, changing between coffees, adjustment routine and cleaning access. Ask how any retention test was performed before comparing figures across grinders. A single-dose design can fit an intentional weighing routine, while its actual convenience depends on how comfortably that routine works in your kitchen.
