Equipment notes
The Lumi B40+ is an electric grinder in MariSteiger's Lumi line, distributed mainly through the Korean market. The Lumi series emphasizes portability and rechargeable operation, and the B40+ is a mid configuration with more capacity and headroom than the B20. 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 to handle a bit more per batch while keeping portability, and those combining travel or camping with home use.
