After a quick lesson from our local espresso guru in Nijmegen, I concluded that my espresso grinder was just not grinding fine enough to pull that perfect shot.
The grinder was already on its finest setting, so I was tempted open it up and see what adjustments I can make.
Luckily, it is a very simple device. It is easy to see the limiter screw in the shot below, and it is just as easy to move it one hole further.
Apparently there has been a batch that do not adjust fine enough.
And now just one more Espresso…
