Cores Cone Grinder C330

Equipment notes

cores is a Japanese specialty-coffee brand, and the Cone Grinder C330 is a home electric conical burr grinder. It drives a stainless conical burr at low speed to limit friction heat, and features a direct structure whose grinding unit detaches entirely for easy cleaning. Low-speed conical grinding tends to suppress heat and fines while producing polyhedral particles that raise extraction efficiency. A dialed stepped selection makes settings easy to reproduce, and the range spans medium to coarse, centering on drip and filter. It does not target the ultra-fine espresso region. It suits home brewers who pour over daily and want both uniformity and cleaning convenience, as a filter-oriented electric grinder.
