1Zpresso J Manual Coffee Grinder review

The 1Zpresso J replaces the JX-Pro on this list because 1Zpresso's own store marked the JX-Pro S as out of stock and unavailable, while the J line was on sale. The J costs $116.00 to $139.00 in USD before tax, depending on the variant (JX, JX S or a bundle with a case). It uses a 48 mm conical burr, the same diameter as the Fellow Opus 2's electric burrs, and adjusts internally with 30 clicks per rotation. 1Zpresso lists grounds capacity of 30 to 35 g, a weight of 705 g, a 304 stainless steel, aluminum alloy and wood build, tool-free disassembly and a foldable handle. It says the burr is built to last up to 200 kg of grinding and covers every grinder with a one-year limited warranty. The trade-off is shipping: 1Zpresso dispatches from Taiwan within 14 working days, and buyers may owe import duties. We compared documented features and published prices and did not run grind tests.
