Compact, Hand-Crated Grinder Lid for Wide-Mouth Mason Jars

Meet a compact, hand-cranked grinder lid designed to pair with standard wide-mouth Mason jars. The ceramic burrs deliver a clean, consistent grind for coffee beans or dried spices, all while you grind directly into the jar you intend to store in. The default setting produces a very fine grind, and you can fine-tune the size by adjusting a gear near the top. Move the pieces closer or farther apart to dial in your preferred texture, then re-tighten as needed. A simple gold screw and the removable handle make reconfiguration quick and trouble-free.

Designed with practical use in mind, this attachment brings fresh-ground flavor possibilities to kitchens, campsites, and power-outage scenarios. It’s ideal for those who value aroma and convenience in a compact, jar-friendly form. The grinder lid is crafted as a complete unit: the cup, lid, and handle are stainless steel, while the grinding mechanism uses durable ceramic for reliable performance. When it’s time to clean, a quick pass with uncooked white rice helps flush the burrs clean without disassembly.
