1Zpresso JX-Pro vs Timemore Chestnut X

The Timemore Chestnut X ($199) and 1Zpresso JX-Pro ($159) are premium hand grinders in the same price tier. The Chestnut X uses 42mm steel burrs with stepped adjustment at 0.6 kg. The JX-Pro uses 48mm steel burrs with stepped adjustment at 0.6 kg. The JX-Pro's larger burrs grind faster — around 30 seconds per dose versus the Chestnut X's 40 seconds. The Chestnut X's smaller but more precisely machined burrs produce a slightly more refined grind distribution. Both are excellent for espresso. The Chestnut X features Timemore's signature slim design with diamond-pattern grip. The JX-Pro has a more utilitarian cylindrical body. The Chestnut X's adjustment dial has a satisfying click mechanism with numbered settings for repeatability. The JX-Pro's internal adjustment is more cumbersome to change. Both have near-zero retention. The JX-Pro is more robust and versatile across grind sizes. Verdict: The JX-Pro is the better all-around value — faster grinding, larger burrs, lower price. The Chestnut X wins on design aesthetics and slightly more refined cup quality for those willing to grind slower.

Burr Size: The 1Zpresso JX-Pro has larger 48 mm burrs compared to the Timemore Chestnut X's 42 mm burrs. Larger burrs generally grind faster and produce less heat, preserving coffee flavor.
