Timemore Chestnut S3 Manual Coffee Grinder

In 2022: X Lite with S2C880 burrs was Timemore’s most comprehensive grinder in terms of grind quality thanks to improvements from the S2C860 burr set of Chestnut X.

X Lite produces exceptionally uniform grounds. However, to be fair, the incredible uniformity of the S2C880 burr set is a double-edged sword: On one hand it preserves coffee aromatics, but on the other it can inadvertently reduce body and richness (Of course, this also depends on the coffee type, primary grind size, and brewing method).

This body and richness is mainly extracted from ground particles in the 200-400µm range. This size range also adds complexity to the coffee’s flavor profile.

CHESTNUT S3 IS TIMEMORE’S BEST MANUAL GRINDER FOCUSED ON POUR OVER (FILTER) BREWING

In 2024, Timemore improved the S2C880 burr set and created the S2C890. This burr set focuses on slightly increasing the proportion of fine particles in the 200-400µm range to add body and richness to coffees brewed using Pour Over/French press methods. Coffee aromatics also become richer and clearer thanks to this change!

The 2024 Timemore Chestnut S3 using S2C890 burrs is a coffee grinder focused primarily on manual brewing methods: Moka pot, Pour over, French Press…

Besides preserving coffee aromatics, Chestnut S3 fully draws out the sweetness and body for your cup of coffee.

TIMEMORE S3 2024 VERSION FOCUSED ON FILTER COFFEE. 2025 VERSION HAS EXPANDED TO ESPRESSO.

• For Timemore S3 grinders manufactured in 2024: Real-world testing shows the maximum fine grind capability isn’t sufficient for brewing coffee with espresso machines: Flair 58, 9Barista, or true espresso machines like Lelit Bianca or Victoria only reach 6 bar at setting 0. The grinder only focuses on maximizing flavor for manual brewing methods like Pour Over (filter coffee) or French Press.
• For S3 grinders manufactured from 2025: The burrs have been recalibrated so the 0 position is much closer together. The finest setting completely chokes the coffee in the portafilter (Lelit Bianca) to the point where extraction is impossible. Espresso with professional machines hovers around setting 1. Currently, the S3 has clearly expanded to ALL brewing methods and has become the most comprehensive grinder in Timemore’s manual coffee grinder lineup.
