No more dribbling near-boiling water onto plastic. Coffee is a ritual—upgrade it.

Tested and refined over the course of a year to deliver uncompromising performance and precision.

Diamond-Like Carbon (DLC) coated lever—a stunning black finish that adds enhanced surface hardness, wear resistance, and a luxurious feel.

Technical Note:

The final design reflects extensive testing and refinement for a better brewing experience—even at a higher production cost. Precision engineering ensures ±0.001” tolerances. The lever’s curves and bevels—initially overlooked—proved critical in promoting smooth flow and preventing post-brew stagnation.

Design Note:

Photos shown reflect Batch Two. Functionality and internal fit remain unchanged.
