A Proven Grinder

Option-O approached the Helor 101 redesign with an old adage in mind: if it ain’t broke, don’t fix it. Much of the 101 worked very well. The REMI, like its predecessor, features a similar aluminum unibody frame—meaning it is milled from a single block of metal for structural integrity—, two steel bearings for stable axle rotation, 38mm conical steel burrs coated in titanium capable of grinding on the spectrum from Aeropress through French Press, and a stepless grind-adjustment wheel for the perfectionist in all of us. This iteration likewise includes a silicone grip band, which can be moved up or down on the barrel according to grip preference or removed for a clean appearance, and an ergonomic crank arm tipped with a beechwood pommel. This is good news for the grinder—fewer slips means fewer scratches—and elbows alike.

Thoughtful Revisions

On the other hand, Option-O has refined some of the less inspired features of the 101. The grinds-catch, for instance, which previously used a silicone seal, now uses an innovative magnetic locking mechanism wherein nine magnets on the grinds-catch lock to nine magnets on the grinder barrel. The result is an easy and pleasing experience. To connect, simply hold the grind-catch close to the barrel and they will snap together with a satisfying click. To disconnect, simply twist and pull them gently apart. The hopper, too, has been improved. In the 101, the barrel was cluttered with three support struts, making it difficult to load the beans without some spillage. With the REMI, Option-O kept only two struts, leaving more clearance in the hopper for easy loading.

Exceptional Grind Quality For Any Method

There is a burr for every barista now that the REMI comes with the option of “Conventional” or “Contemporary” burrs. The “Conventional” burrs, however, are anything but conventional.
In fact, these burrs produce exceptional particle uniformity on par with other premium, non-espresso grinders, electric and manual alike, which means a clean cup of coffee for brewing methods like V60, Kalita Wave, and even Chemex. The Conventional burrs now come with a titanium coating. The “contemporary” – or espresso burrs – are engineered specifically for the finer range to accommodate the needs of those with an espresso machine, Robot, or Ibrik, and a penchant for finding the precise grind. Like the conventional burrs, the contemporary burrs are also coated in a layer of titanium nitride, which reduces surface friction, making for a quick and nearly effortless grinding session, and increases the lifespan of the burrs by a factor of five.
