C3 ESP Pro Steel Burr Grinder

The StepUP Coffee Manual Coffee Grinder Chestnut C3 ESP Pro is a portable burr coffee grinder built for precise, repeatable grinding across espresso, pour over, and French press. It uses a CNC-machined steel conical burr, a twin-bearing axis for better alignment, and stepless-style micro adjustment with about 30 to 36 clicks per rotation, or roughly 0.0233 mm per click. Compared to blade grinders, it delivers a more uniform grind size with less heat and better flavor retention.

• CNC-machined steel conical burr for consistent particle size
• Micro adjustment range suited to espresso grind, filter coffee, and French press
• Twin-bearing shaft design helps improve stability while grinding
• Foldable handle and all-metal body pack easily for travel or camping
• Approximate 25 g capacity works well for one to two cups
• Manual operation preserves fresh ground coffee aroma and oils without electricity

This hand grinder fits real daily use, from dialing in espresso at home to making fresh coffee in a hotel, office, camper, or campsite. Unlike larger electric grinders, it is compact, quiet, and easy to carry. The solid metal build is designed for regular use, and the fine adjustment gives coffee drinkers more control over different coffee brewing methods. If you want a manual coffee grinder that balances travel-friendly size with espresso-capable precision, the Chestnut C3 ESP Pro is a reliable choice.
