The lovely and colourful porcelain flower petal dripper is an ultimate craft. Each piece is hand-made by Japanese craftsmen using traditional Japanese Arita ware technique. What is compelling is the distribution of petal ribs on the inner wall of the coffee dripper. They allow the coffee powder to expand perfectly and to create space between filter paper and dripper. The pattern of sparse in the upper and dense in the lower also contributes to the effect of variable speed of water flow: when water level reaches 60-70% of the dripper, the flow rate will slow down. It is therefore hailed as a "full of sweetness" filter cup as it does not only influence the fruitiness and acidity, but also fully extracts the sweetness and moderate bitterness, which brews a cup of coffee full of personality.
