Turn Any Mason Jar into a Manual Coffee Grinder

The Diatomiteco Mason Jar Coffee Grinder Lid reimagines your favorite jar as a compact, hand-powered coffee mill. Designed to fit wide-mouth mason jars with a 3.1 inch internal diameter, it transforms ordinary storage into an efficient brewing setup in seconds. The stainless steel lid pairs with a ceramic burr to deliver a steady, aroma-preserving grind, so you can enjoy fresh coffee at home or on the go.

Whether you’re preparing for a camping trip, a weekend outdoors, or a power outage at home, this lid adds portability and convenience without sacrificing quality. Grind directly into the jar you plan to store or transport, reducing transfers and keeping grounds ready for brewing.

Premium Grinding Experience

  • Ceramic burrs work with a lightweight, low-heat action to help preserve coffee aroma and flavor during grinding.
  • Grind directly into the mason jar you intend to store, creating a simple, self-contained workflow.

Adaptable for Any Setting

  • Ideal for camping, travel, or power outages—turn any mason jar into a portable coffee mill in moments.
  • Adjustable grind size lets you move the gear piece along the threaded rod to dial in your grind.

Easy to Clean and Built to Last

  • Disassembles for thorough cleaning and rust-proof durability, ready for regular use in kitchen or outdoor environments.
  • Quick cleaning tip: a small rice grind helps remove residues and odors between uses.

Note: Mason jars are sold separately. This lid provides a practical, hands-on way to explore fresh-ground coffee with familiar containers.
