SHAPE: Cylindrical with Convex Bottom
The shape was created by I.M.S. to obtain the proper ratio between the base and height of the coffee puck in relation to capacity. The filter is cylindrical with a convex bottom to collect the coffee towards the center during percolation. This shape has been designed to exploit the whole coffee puck, which also facilitates drying and expulsion.
