The flower dripper keeps a deep filtering layer by making water circulation from the center to outside. To prevent the unpleasant taste from going into extracted coffee, faster and smoother water flow is required. After much research, CAFEC reached this ideal flower shape. Because water does not stay in the dripper, the amount of water poured in and drawn down is relatively the same.
The Drippers cone-shape allows a deep filtering layer to form which allows water to evenly circulate in the dripper. This also allows for the water to permeate all the coffee grounds so that the coffee becomes smooth and bodied. The shape also includes a wide handle for easier grip and a balanced hold.
These are not only for aesthetic appeal but has a purpose. Made by creating indentations in the inner wall allowing a layer of air to be kept between the paper and the dripper. This helps the coffee expand better and not be restricted and also helps the brew to pass through.
A single hole at the center of the bottom of the brewer creates a deep filtering layer that aids in the extraction of coffee flavors. The bottom of the hole is ribbed to create flow paths for the coffee which allows for stability in coffee extraction.
