Key Features of the Chestnut C3 ESP Pro Model:

• Optimized for Espresso (ESP Precision) – Unlike the standard C-series models, the ESP version features a finer thread and a modified adjustment mechanism. This allows the barista to make micrometric changes in the grind, essential for the correct "dialing in" of an espresso. Thanks to a higher number of clicks per turn, the C3 ESP Pro offers sufficient variability even for professional 58 mm portafilters, overcoming the limits of common universal grinders.
• S2C660 Grinding Burrs (Spike to Cut) – The grinder is equipped with 38 mm conical burrs made of hardened stainless steel (SUS420) with patented S2C technology. This system works in two phases: the bean is first "chopped" by the spikes in the upper part of the burrs and then finely ground in the lower part. The result is significantly higher grind uniformity, a reduction in the share of fines, and better extraction with a clearer flavor profile.
• Foldable Handle and Pro Version – The "Pro" designation signifies the presence of the iconic foldable crank. This mechanism is not only practical for travel, but in its unfolded position, it provides firm support and stability while grinding, which is crucial for fine espresso grinding where bean resistance is higher.
• All-Metal Durability and Textured Surface – The grinder body is made of aluminum alloy with a distinct diamond pattern on the surface. This "anti-slip" design guarantees a firm grip, so the grinder doesn't rotate in your hand even when grinding harder, light-roasted beans.
