Timemore Chestnut S3 / S3 ESP Coffee Grinder

We provide a 1-year warranty on all our Timemore products.

In 2025, Timemore launched the S3 ESP to complement the existing S3 (launched in 2024).

This makes the S3 ESP Timemore's second grinder with an external grind adjustment - the first being the S3. The S3 ESP features Timemore's latest burr set - the S2C-420-EI. Compared to the S2C890 featured in the S3, this burrset has 8 flanges as opposed to the traditional 6 flanged design. Based on Timemore's testing, the S3 ESP burr set produces a rounder, sweeter and more bodied cup of coffee. Ideal for espresso with medium to dark roasts. Whereas the S3 burr set produces a cup with more clarity and flavour seperation, which is ideal for filter / pour over with medium to light roasts.

Both S3 and S3 ESP can grind for espresso, filter and french press. But the S3 ESP, like its name suggests, favours espresso. While the S3 is more suited for filter. Which grinder you choose would depend on which brewing style you favour. Apart from the difference in burr, they share identical features. They both have an external dial adjustment that changes the grind size by 15 microns per click, they both have a folding handle for easy storage and transport. And lastly, they both have precision bearings which will result in a more uniform and consistent grind, giving you better tasting brews.

Summary: S3 favours filter / pour overs, S3 ESP favours espresso. Both are great all purpose grinders.

Key features:

• External Click Adjustment: Fine tune your grind settings down to 0.015mm steps, with the scales labelled so you no longer have to manually count from zero (like with the C3 series).
• Micro-adjustments: With 15 clicks of mirco adjustments within the espresso range alone, and a total of 90 clicks of adjustments in its entire range. This makes the S3 the most accurate grinder in the entire Timemore range.
• High Precision Bearings: Increased precision by 20%, with a stricter tolerance of 5 microns compared to the previous 7 microns.
• Built for Durability: Full metal, unibody construction.
• Foldable Handle: The patented spring-assisted handle not only looks sleek, but makes the grinder more compact and easier to store. It also shifts the centre of gravity and reduces the likelihood of the grinder tipping over. 
• Anti-slip Silicone Pad: Located on the base of the grinder, the silicone pad prevents the grinder from slipping on your countertop.
