The typical product of Nakayama Sekizai Kohboh is the “millstone,” one of the traditional Japanese instruments.
1
Insert the handle into the hole and gently strike it into it with the rubber hammer.
2
Put 5 or 6 beans into it. Rotate it counterclockwise and gently. Put 5 or 6 beans into it on every rotation, and continuously turn it around. When it becomes full of power in the mill, powder will begin to come out from the joint. Depending on the speed of rotation and the amount of beans, its fineness of powder changes. Please grind them as you like.
3
Take the powder off from the slit with the brush. Take out the powder coming from the tray with the brush.
How to Use the Millstone
Grinding coffee beans with the coffee mill
1
Place tealeaves on the mill, drop them little by little into the hole in the center while turning it around. If you put too many leaves in it, they will get stuck in the hole.
2
Slowly rotate it, put tealeaves little by little, and fine powder will come out. If you rotate it fast, rough powder will come out. Coffee tastes good even if coffee is ground roughly, but tea tastes better with fine powder.
3
Take the powder out of it and move it to the container. That’s it.
