Specifications

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

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

Heating systemDual boilers and heat exchangers can brew and steam at the same time with stable temperature. Thermoblocks heat fast but drift more. |
Not stated |
PID temperature controlA PID controller holds brew water within about one degree. Unstable temperature is the most common cause of sour or bitter shots. |
Not stated |
Adjustable brew temperatureLight roasts like hotter water, dark roasts cooler. Without adjustment you are stuck with one setting. |

Pre-infusionWetting the coffee puck at low pressure before full pressure evens out extraction and forgives small tamping mistakes. |

Portafilter size58 mm is the café standard with the widest choice of baskets and tampers. Smaller sizes work, but accessories are scarcer. |
Not stated |
Pump pressureEspresso 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. |

Pressure gaugeA gauge shows whether your grind and dose are right while the shot runs. |
