Brewing

Heating system

Dual boilers and heat exchangers can brew and steam at the same time with stable temperature. Thermoblocks heat fast but drift more.

Portafilter size

58 mm is the café standard with the widest choice of baskets and tampers. Smaller sizes work, but accessories are scarcer.

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.
