Hi Giovanni,


Here are three options for settling the espresso.


Glass A: single-walled gives good settling.


Glass B: Double walled gives a lesser settlement because of the shape of the glass.


Tank C: Gives the most settlement, watch this from beginning to end, a nice layer of foam will form and a dark bottom.

1: Glas A Settling

2: Glas B Double-walled

3: Tank C
