Weber Workshops 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 now made exclusively for Weber Workshops. These filters have a 0.15mm thickness, and a 54mm diameter which is perfect for 58mm baskets.

Increasing balance and extraction

Placing paper filters between the coffee puck and the holes in the basket reduce clogging of the portafilter 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 in your worksflow, but the effort is rewarded with a perceptibly improved shot of espresso.

How to use

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 a smooth liquid exit to the pores of the portafilter. It’s engineered to improve your espresso. The paper can be washed and re-used, but keep in mind that the quality of your shots will have a significant decrease. Therefore it is not recommended by Weber Workshops.
