What's the worst coffee worldwide?

It seems, that I actually more or less solved the problem with the metal taste on the classic aluminium moka pot. Medium degree of grinding or even a little more coarse seem to do right. I actually grind on 8 of 15. The coffee runs through a lot faster and I think, the contact with the metal is now seemingly short enough to avoid "distinct" metal taste. So far so good, we will see.
