Expert Analysis
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.
Our Verdict
The choice between the 1Zpresso JX-Pro and the Timemore Chestnut X comes down to your priorities and budget. The 1Zpresso JX-Pro is the more affordable option and offers great value. The Timemore Chestnut X, while pricier, may justify the investment with superior grind quality and features. Both grinders are capable of producing excellent espresso grinds when properly dialed in.
