Le Maestro Auto Espresso
Touch screen control · 20-bar extraction · Hot & cold modes · Steam wand
Hot espresso is the standard. Cold espresso is the trick. Le Maestro does both from one portafilter, 20 bar pressure, PID temperature control, the same shot you'd pull on a summer afternoon or a winter morning. The crema reads the season.
The Le Maestro Auto Espresso is a dual-temperature espresso machine with touchscreen control, 20-bar pump pressure, and NTC+PID temperature regulation. Hot espresso at 194–203°F, cold-brewed shots at 39–50°F.
Hot espresso. Cold espresso. One machine.

Care & maintenance
Espresso machines live longer when you treat the boiler and group head like they matter.
- Backflush weekly: Run a cleaning cycle with espresso machine cleaner through the group head to remove coffee oil buildup. Skip this and extraction slows, flavors go stale.
- Descale monthly: Use a descaling solution in the water reservoir. Mineral deposits restrict flow and damage the heating element over time.
- Wipe the steam wand immediately: Purge steam after every milk session, then wipe with a damp cloth. Dried milk is concrete, and it clogs the tip.
- Empty the drip tray daily: Coffee oils turn rancid fast. A full tray smells sour and attracts mold.
Frequently asked
How does cold extraction work?
The machine chills water to 39–50°F, then forces it through the portafilter at 20 bar. You get a cold-brewed shot without the 12-hour wait, smoother, less acidic, no ice dilution.
What is the difference between Italian and American modes?
Italian mode extracts a short 1–1.5 oz espresso shot. American mode runs longer, closer to 3–4 oz, diluting the espresso into a lungo or Americano base. Same grounds, different volume, different strength.
What grind should I use?
Fine espresso grind, slightly coarser for cold extraction to prevent over-restriction. Dial it in by timing the shot, aim for 25–30 seconds for a double espresso, 35–40 seconds for cold brew mode.
Is the portafilter pressurized or non-pressurized?
Non-pressurized, commercial-style 2.5 in. You control the grind, dose, and tamp, the machine does not fake crema. It rewards precision and punishes carelessness, which is how espresso should work.
How long does it take to switch between hot and cold modes?
About 3–5 minutes. The machine adjusts the boiler temperature and stabilizes before extraction. You cannot toggle instantly mid-shot, but the wait is shorter than brewing cold brew overnight.
