Premium manual grinding with ESP precision

The TIMEMORE Chestnut C3 ESP Pro is a premium manual grinder built for espresso lovers and curious brewers alike. With upgraded S2C steel burrs, it delivers a clean, consistent grind that helps preserve aroma and flavor as you brew. The design blends tactile satisfaction with practical performance, making every grind feel deliberate and rewarding.

Espresso-ready design and flexible precision

This model centers an ESP approach, featuring patented S2C660 stainless steel burrs for heightened precision and efficiency. A stepwise, but effectively stepless adjustment system lets you tune grind size with114 per-click increments of 0.0233 mm, making it easier to move smoothly from fine espresso grind to coarser options for other brews.

From the first adjustment to the last grind, you’ll notice how small changes translate to measurable differences in extraction. The grinder accommodates a range of brews without needing to switch equipment, encouraging experimentation with different beans, roasts, and water temperatures.

Durable, precise construction you can rely on

Durability is at the core. The C3 ESP Pro uses an all-metal aluminum alloy body with no internal plastic parts, paired with a dual-bearing setup for steadier, more controlled grinding. This combination supports a smoother action and more uniform particle size, which can contribute to steadier extraction over time.

The foldable handle adds to practicality, enabling easy packing for travel and storage without adding bulk. The compact form and thoughtful weight balance make it comfortable to hold for longer grinding sessions yet light enough for everyday use.

Versatile, user-friendly grinding you can see and feel

With a compact 52 mm burr and a 25 g capacity, it’s sized for practicality in daily routines—enough for a cup or two before a refill. The stepless design ensures you can dial in just the right coarseness for espresso, pour-over, or French press. The result is a flexible tool that supports a variety of brewing methods while staying true to its manual roots.

Real-world use cases include a quick morning espresso, a measured pour-over during a weekend ritual, or a travel-friendly setup that travels in a backpack. While it doesn’t guarantee a specific outcome, the ESP Pro opens up possibilities for exploring different grind sizes and bean profiles with consistent control.
