Hario V60-01 Ceramic

Hario V60 - 01 Ceramic Coffee Dripper has a ceramic cone-style filter with vortex radial drain pattern and an open end, allowing to drop/drip coffee as it needs providing a greater depth and character during extraction

Why the cone shape? The cone shaped paper filter adds depth to the coffee layer, so that the water flows to the center, extending the amount of time it is in contact with the ground coffee.
