The TIMEMORE Brewer Set has everything you need to begin producing perfect pour-over coffee at home and includes an acrylic Crystal Eye dripper and a matching glass server. Time More Dripper is designed with a concave principle, the lower area of the dripper, instead of slowing down the brew actually increases, making the water flow more smoothly and the extraction more uniform. 1 - Insulating level - the filter paper is 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. Inside the box: Crystal Eye Dripper 01 Glass Server 300ml Available in Transparent and Transparent Black
