Niche's flat burr single-dose grinder pairs 83mm burrs with the brand's cult following among espresso nerds, promising the clarity and consistency flat burr devotees chase. The catch is stark: almost no one owns one yet, so you're buying on theory and brand trust, not the field-tested proof that exists for the conical Zero. If you're comfortable being an early adopter and value the Niche workflow enough to take that leap, the fundamentals look sound. If you need to see a grinder survive a few thousand shots in real kitchens first, wait six months and check back.
