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.
The Niche Zero is the single-dose grinder for people who know they love traditional espresso: medium-dark roasts, chocolatey shots, milk drinks that taste like dessert. It delivers near-zero retention, whisper-quiet operation, and years of reliable service, but the conical burrs that make darker beans sing will flatten fruity Ethiopians into something polite and forgettable. Enough owners have bought a second grinder specifically for light roasts that the pattern is clear. If you're committed to classic espresso profiles and want a grinder that just works, this is still a smart buy; if you're still exploring what you like or already deep into the light roast game, the burr geometry will fight you.
