1Zpresso JPpro

Equipment notes

The JPpro is a J-series manual grinder from the Taiwanese brand 1Zpresso (manufactured in China). It uses a conical stainless steel burr and follows the J-series adjustment style, feeding beans from the top and reading settings on a numbered scale. The J line broadly targets filter brewing such as pour-over and French press. The conical burr tends to build body and leave some fines, but 1Zpresso's precise assembly and calibration deliver stable filter-range uniformity. The stepped click adjustment makes settings easy to memorize by number and repeat, covering the filter range from coarse French press to pour-over. Tool-free disassembly and cleaning is another J-series strength. It suits users centered on pour-over and filter brewing who want repeatable settings at a reasonable price.
