Arita Deep Dripper PRO CAFEC White Deep 45 Deep Dripper – Deep Filter Layer Method. "The deep filter layer created in a cloth dripper can also be created in a filter paper dripper?" Shigeji Nakatsuka, president of Sanyo Sangyo, has dreamed of creating such a paper filter solution for many years, as a pioneer in filter paper production. Now, his dream is finally taking shape with the Deep Dripper, which fully approximates the cloth dripper brewing method. The Deep Dripper PRO comes in only one size: for 3-7 cups. Cafec hasn't made another small, deep dripper because a deep filter layer can't be created with a small amount of ground coffee. This is the only size: the volume of grounds is larger, the filter layer is deeper/higher. The deep filter layer method is a brewing structure that maximizes the extraction of a better, more pleasant flavor from coffee by creating a deeper filter layer: the filter layer is thicker, and the contact time of the water with the ground coffee particles is longer. This results in a much more pleasant and full-bodied flavor. To create a larger filter layer in a cone-shaped dripper, Sanyo Sangyo was the first in the world to invent the new DEEP 45 standard and develop it as the Deep Dripper PRO. DEEP 45 is a new standard, developed based on Sanyo Sangyo's own brewing theory. It is designed to create a deeper filter layer, thanks to which the bottom angle of the dripper and paper filter is sharper than the standard 60 degrees, reaching 45 degrees.
