Deep wrinkles and sufficient thickness allow for smoother and cleaner extraction.

When using the conical shape, which has a thicker layer of coffee powder than the wave shape, there is a difference in the extraction of the upper and lower layers of powder. This gives the extracted coffee a more complicated flavor. The taste of the same coffee can be different depending on the type of paper filter used. We hope you enjoy the difference in taste between the conical and wave type coffees.
