Pump pressure

Espresso is brewed at about 9 bar. Higher numbers on the box are maximum pump ratings and do not make better coffee, so we do not score them.

Milk

Milk frothing

A manual steam wand gives the best microfoam for latte art but takes practice. Automatic systems are easier but less flexible.
