All CONVEX bases have a slightly curved surface for pressing the espresso powder and are made of solid stainless steel: 1.4305 on a CNC lathe. Similar to the American Curve, the difference between the center and the outer edge is 1.5mm.
Why Convex?
Normally, the surface of the espresso pressed in the portafilter does not play a major role: whether flat (flat) or convex (curved), there is enough space between the espresso surface and the shower sieve so that the water can be evenly distributed over the espresso and the powder also penetrated evenly. However, if flat sieves are used or significantly more than 7g (1-cup sieve) or 14g (2-cup sieve) are used, it may happen that there is not enough space between the espresso powder and the shower sieve for optimal distribution of the brewing water. A Tamper Base Convex can be used for this purpose so that depression remains in the middle for optimal water distribution.
