Rusty coffee grinder - Restoration

In today's episode we will show you the renovation of a tin coffee grinder. Coffee grinder was bought by my wife Veronika and I was renovating at her request.

Something about the history of coffee grinding

Initially, the coffee beans were crushed in mortars, or milled in stone grinders to fine powder. Only later, various small and large metal stone grinders were produced. During the First World War, soldiers bought only internal movements for price reasons and then made their own packaging from used ammunition. These models can still be found in collectors' collections.

In the past, practical tools for day-to-day use are more like decoration.

If you have any information about coffee grinder and companies that made them (period brochures, ads, model names, years of production), you can share them with others on my facebook site:
