Aromaster AREM26 vs CASABREWS CM5418

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

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

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

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.

A gauge shows whether your grind and dose are right while the shot runs.

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

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

Heavier machines stay put when you lock in the portafilter. Lighter ones are easier to move and store.

Higher wattage usually means faster heating, but it says nothing about coffee quality.
