C5 Pro's tight grind profile lifts the ceiling on extraction bringing greater clarity, standout sweetness, and a finish that wins. A grinding path 16.23% longer than the previous gen S2C660 improves consistency across brew methods. Finer grind for espresso needs. Coarser for pour-over. With a 5% improvement in grind consistency over C3S Pro allows for higher extractions without astringency — a cup that holds up as it cools.
