9Barista Stovetop Espresso

The World's Only True Stovetop Espresso — Mk.1 · Mk.2 · Mk.2 Pro · Starter Pack — 9 Bar · 93°C — No Electricity · Engineered in Cambridge UK

A moka pot brews at 0.5–2 bar with water that often exceeds 100°C. That produces strong concentrated coffee — but not espresso. Real espresso requires water at precisely 9 bar of pressure and 93°C simultaneously. Until the 9Barista, no stovetop machine in the world had ever reliably achieved both at the same time. The 9Barista was designed by William Playford — a jet engine engineer with a PhD from Cambridge University's Whittle Laboratory — who applied the same engineering principles that govern turbine pressure, temperature control, and heat exchange in aerospace to build a patented twin-boiler stovetop system. The lower boiler reaches 179°C, creating exactly 9 bars of steam pressure. A coil heat exchanger simultaneously cools the pressurised water to 93°C before it reaches the coffee. The result: genuine double espresso with rich crema, indistinguishable from a premium counter machine when beans and grind are dialled in.

Every 9Barista is engineered, manufactured, and inspected individually over 150 times at 9Barista's Cambridge workshop before it leaves. Die-cast and machined brass, electroless nickel plating, one moving part (a spring-operated pressure valve), and zero electronics. Nothing to fail electronically — ever. Di Pacci stocks the full 9Barista range — Mk.1, Mk.1 Starter Pack (with grinder + 250g coffee + IMS basket), and Mk.2 in Standard and Pro configurations. Ships Australia-wide.
