Most portable espresso machines use a 51mm basket — a compromise that produces acceptable espresso. The Super58 uses a 58.35mm basket, identical to the espresso machines in your local cafe. That difference in size translates directly to better extraction, more crema, and a cup that actually compares to what a trained barista would pull.

Why 58mm changes everything

The portafilter basket size is one of the most significant factors in espresso quality. A 58mm basket allows for an 18–20g dose of coffee — the professional barista standard. A 51mm basket maxes out around 14–16g. More coffee, distributed more evenly across a larger surface area, means the water flows through more uniformly. Uniform flow means uniform extraction. Uniform extraction means better flavour.

The Super58 doesn't compromise on basket size to save space. It's a genuinely professional brewing setup that happens to be portable.

Adjustable pressure — 0 to 15 BAR

The OPV (over-pressure valve) on the Super58 is adjustable from 0 to 15 BAR. Traditional espresso is pulled at 9 BAR. The ability to adjust lets you experiment: lighter roasts often extract better at lower pressure (6–8 BAR), darker roasts at the classic 9 BAR. This is a feature you'd expect on a machine costing $600, not $269.

Dual brewing modes add further control: pre-infusion mode soaks the puck gently before full pressure hits, reducing channelling and improving flavour complexity. Direct extraction is faster and produces a bolder result. You choose based on what you're brewing and how much time you have.

"I've used Wacaco, Staresso, Nanopresso. The Super58 is in a different category — the crema is thicker and the shot has actual sweetness."

Who is the Super58 for

The Super58 is for anyone who travels and refuses to drink bad coffee. Business travellers who stay in hotels where the in-room coffee is undrinkable. Campers who want real espresso at the campsite. Office workers who want a shot at their desk without a $1,500 machine. People who visit family and don't want to use whatever machine is there.

It's also a strong secondary machine — if you have a home espresso setup and want something for travel or the office, the Super58 is the most credible portable option available at this price.
