The Timemore Chestnut S3 represents the latest release from Timemore, introducing an external click adjustment system with an impressive 15-micron step— the finest adjustment in the Timemore range.


Featuring SUS420 serrated stainless steel conical burrs, the S3 builds upon the spike-2-cut design of the Chestnut X. The S2C890 burr set, an improvement over the X Lite's S2C880 burr set, effectively reduces fines and enhances grind distribution. Compared to its counterparts, the Chestnut X and X Lite, the S3 produces an even sweeter and cleaner cup.


An additional upgrade includes the incorporation of 'Red Ring' bearings with a tighter tolerance of 5 microns, as opposed to the previous 7 microns. This enhanced precision increases centricity, contributing to a sharper grind distribution for an brighter overall cup.
