Fellow's first foray into espresso, the Open Box Opus offers both espresso and brewed coffee grind ranges in a single grinder. The Opus achieves this with both an outer 41-step macro adjustment range, and an inner 'fine-tune' range that allows you to adjust your macro grind setting 6 micro-steps in either direction. Functionally, this lets you switch from espresso to brew grind ranges in a single turn, with fine-tuning for flavor possible by removing the hopper and adjusting the inner range. Outside, the Opus features a compact, well-designed footprint thanks to its single-dose hopper and magnetic catch cup. Equipped with tap-to-grind timed dosing and unique anti-static technology cribbed from the larger Fellow Ode, the Fellow Opus is truly do-it-all multipurpose grinder.
