Weber Workshops have teamed up with Cafec in Japan, the leading producer of high-end coffee paper filters, to bring the first-of-its-kind paper filter made specifically for espresso, and made exclusively for Weber Workshops.
 
Why a paper filter?
Paper filters under the coffee puck reduce clogging of the portafilter/unifilter basket holes, thereby facilitating a more even extraction. It also prevents higher flow right at the basket holes, allowing more even water flow throughout the puck, especially in the bottom section. This enables the use of a finer grind, which increases extraction yield while keeping shot times the same. It does introduce an extra step, but the effort is rewarded with a perceptibly improved shot of espresso.
 
About the paper
In the paper creation process, the roller and the dryer drum operate at different speeds, yielding two different textures on either side of the paper. The smooth size goes against the coffee, and the rough side (the “crepe”) faces down for smooth liquid exit to the pores of the portafilter. It’s engineered to improve your espresso.
