Option-O built its reputation on a specific bet: that stripping away fines would unlock clarity light-roast obsessives had been chasing for years. The P64 proved that bet, then got replaced by the P80 with bigger burrs and tighter tolerances, so you're shopping a discontinued model unless you find used. What you get is exceptional flavor separation and near-zero retention, but these grinders pull thin, bright shots that read beautifully yet lack the syrupy body traditional espresso drinkers expect. If you brew fruit-forward naturals and want to taste every fermentation note, the Lagom family delivers; if you make milk drinks or prefer chocolatey medium roasts, a conical grinder will serve you better.
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.
