MariSteiger Lumi S60+

Equipment notes

The Lumi S60+ is an electric grinder in MariSteiger's Lumi line, distributed mainly through the Korean market, and sits at the larger end of the series. The Lumi series emphasizes portability and rechargeable operation, and the S60+ targets fuller capacity and more headroom. It uses a conical ceramic burr. Ceramic is heat-resistant and wear-tolerant, so it runs cool, and the conical shape passes somewhat more fines, favoring a cup with body. Ceramic edges are duller than steel and wear gradually over time. Grind size is set with stepped adjustment. It suits users who want the largest capacity within a portable line, and those preparing several cups at once for combined camping and home use.
