Suitable for 1-3 cup size brew
There are 3 levels in the design:
1 – Insulating level – the filter paper completely attached to the smooth top part of the dripper so water cannot get through.
2 – Brewing level – where the brewing action should take place.
3 – Powder level – the ground coffee will fill the bottom area which is less ribbed and more flume to encourage the water flow and thus reducing the chance of over extracting.
