It makes coffee without electric power, but this is not the only interesting thing about it.
A Canadian company started to market a coffee brewer made of wood. The device has to be placed on the top of a cup; then, two spoonful of ground coffee need to be put in it, and hot water poured over the coffee. The coffee drips down in the cup within 3-4 minutes, mixed with the special flavor of the wood.
The coffee maker can be made of maple, cherry or walnut. Maple and cherry flavors match citrus and seed flavored coffees, whereas walnut matches darker, earthen flavored coffee types.
