Espresso quality machines you know
The thickest creamiest espresso I could pull so far was with a Bezzera Strega and a Ditting grinder with cast iron burrs. The second thickest was with a Cremina. I have several machines to test and the Strega can easily give me a very thick mouthfeel even at low doses. I used Quarta Rossa which is a blend with Robusta and really dark.
