Hi,

I've problem with my espresso. After I did whole service of the machine (NS Oscar) without any improvement in taste, I consider grinder to be my weakest link.
I've noticed that in "espresso setting" (ratio 2:1) burrs rub quite loud. Is it normal? Can it be the issue for inconsistent and sour espresso? Burrs seem sharp, yet I have no idea how much coffee they ground so far (I bought it second hand).
