Brewing

Built-in grinder

Fresh grinding right before brewing matters more for taste than almost anything else. A built-in grinder saves buying a separate one.

Grind settings

More steps let you fine-tune extraction for different beans. Below about 15 steps, dialing in espresso gets hard.

Heating system

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

PID temperature control

A PID controller holds brew water within about one degree. Unstable temperature is the most common cause of sour or bitter shots.

Pre-infusion

Wetting the coffee puck at low pressure before full pressure evens out extraction and forgives small tamping mistakes.

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.

Convenience

Water tank

A bigger tank means refilling less often. For two milk drinks a day, about 60 oz lasts several days.
