William Playford, 9Barista’s founder, has two great passions in life; jet engines and espresso coffee.
He started building jet engines as a teenager and went on to study jet engineering at Cambridge.
His love for good coffee started in Italy, slowly turning from love to something of an obsession.
But how are these two things linked?
Well, top quality espresso machines need three things to make perfect coffee: high pressures, perfectly controlled temperatures and precision engineered components. The same three things that a jet engine requires.
William decided that if anyone could engineer a small but perfectly formed home espresso machine, it was him.
Finally, five years later, 9Barista, the first ever jet-engineered stove top coffee machine was born.
9Barista consistently produces perfect brewing conditions just like the large machines at your local café. The result? Exquisite espresso with a perfect crema.
Constructed from solid brass, and with no electronics or moving parts (apart from a spring) 9Barista is engineered to last a lifetime.
9Barista does not use wasteful pods, and is designed to last a lifetime, making its carbon footprint inherently low.
9Barista uses fresh ground coffee, not pods. Coffee pods are expensive and wasteful. If you add up the cost, 9Barista will pay for itself within about a year.
Small & versatile
Small, compact and perfectly formed, 9Barista works on any cooker, from electric hobs including induction, to gas or Aga and even on a camping stove
9Barista is beautifully simple. It has no electrical components, and only one moving part.
9Barista produces professional quality espresso by using entirely new technology that has been proven and patented, and sets it apart from all other espresso machines.
9Barista uses a unique twin-boiler system. One boiler sets the brewing pressure, while the second regulates the brewing temperature.
The high-pressure boiler is heated on a stove top until it reaches 179ºC, increasing the pressure inside to 9 bar precisely.
At 9 bar pressure the spring-loaded valve opens, allowing water to flow from the high pressure boiler into the coil heat exchanger.
As the high pressure water from the first boiler passes through the coil, it is cooled from 179ºC to 100ºC, while remaining at 9 bar pressure. The water then passes through the fin heat exchanger where it is cooled further to 93ºC.
Now the water is at precisely the right pressure and temperature to pass through the ground coffee, producing a perfect crema-cloaked espresso in the cup at the top.
Simple, but at the same time, deliciously clever.
