The Chestnut C3 ESP Pro is a manual burr coffee grinder built for consistent grinding across espresso, moka pot, pour over, and French press. It uses a 420 stainless steel conical burr set with S2C geometry and fine adjustment of about 23.3 μm per click, giving you repeatable control in a compact grinder that holds 20 to 25g of beans.

• 420 stainless steel conical burrs help produce a more uniform particle size for cleaner extraction
• Fine stepped adjustment supports espresso through coarse French press grinding
• Single-dose capacity of 20 to 25g suits 1 to 2 cups while keeping beans fresh
• Foldable handle and compact body make it easy to pack for travel, camping, office, or hiking
• Manual grinding avoids heat buildup that can affect flavor in some electric grinders
• All-metal anti-slip body is designed for stable daily use and easy handling

Compared to basic blade grinders, the conical burr system gives better grind consistency and more control over extraction. Unlike bulky electric coffee grinders, it needs no power source and takes up very little space in a travel kit or home coffee setup.

This grinder works well for home baristas dialing in espresso, campers brewing with a moka pot, or anyone who wants fresh ground coffee at work. If you want a portable coffee grinder with precise burr adjustment and durable metal construction, this is a practical upgrade for everyday brewing.
