  • Size

    Compact: 8" Width or less

    Mid-Size: 8-12" Width

    Full-Size: 12" Width or more

  • Temp Control

    Single Boiler: A single boiler handles both brewing and steaming.

    Double Boiler: Dedicated brew and steam boilers allow for increased consistency.

    Thermoblock: A quick-heating boiler alternative for faster warm-up times.

    Heat Exchanger: Flash-heated brew water and a large steam boiler lets you brew and steam simultaneously.

    Boiler+Thermoblock: A traditional boiler for brewing with a thermoblock for instant steaming.

    Double Thermoblock: Two dedicated thermoblocks offer instant brewing and steaming.

  • PID Temperature Control: A group-integrated thermoblock with electronic PID control offers exacting temperature settings.
  • Full-size Portafilter: A classic 58mm portafilter and a bevy of high-quality baskets ensures easy espresso prep with industry-standard accessories.
  • Adjustable OPV: An externally-accessible screw lets you set the max pressure the pump will push through your group head. In addition to giving you an extra parameter to play with, this opens up the Steel Uno to backflushing.
  • Advanced Programming: Set and save power saving, pre-infusion, dwell time, and shot length through the low-profile screen.
  • In-line Pressure Gauge: The face-mounted pressure gauge offers an easy view to brew pressure over the length of your shot.
  • Wood Furniture: The Steel Uno comes standard with walnut accents at its portafilter and steam knob.
    • Pros
      • Excellent Espresso: The Steel Uno brings excellent, easily recreated espresso thanks to its basket options, tight temperature controls, and short water path.
      • Larger Format: The Uno also offer a bit more room to work than its smaller counterpart, the Dream PID.
    • Cons
      • Steam Surfing: The Uno only comes with a single thermoblock inside, meaning you still need to raise the temperature for steaming, then bring it back down for brewing—lengthening critical morning TTL (time to latte).
