Why the name Knock?
After the first ramping of the espresso, a light knock is applied to the side of the portafilter, which causes all the espresso powder to fall from the side into the portafilter. Then it is tamped again. To avoid having to use the tamper base for this light knock on the portafilter, which could damage the soft portafilter, or even the wooden handle, the tamper can now be knocked with the silicone ring incorporated in the base. We have legally protected this invention.
Normally, the surface of the espresso tamped in the portafilter does not matter much; whether Flat (flat) or Convex (convex), there is enough space between the espresso surface and the shower screen so that the water can spread evenly over the espresso and the espresso powder also penetrates evenly. However, if flat sieves are used or significantly more than 7g (1-cup sieve) or 14g (2-cup sieve) are used, there may be too little space between the espresso powder and the shower sieve for optimal brewing water distribution. For this purpose, a Convex tamper base can be used, which leaves a trough in the center for better water distribution.
