The 9Barista is lightweight and easy to carry, featuring a perfect metallic finish, allowing you to enjoy fresh and rich espresso while camping or traveling.
At the core of the 9Barista is its unique twin-boiler system, which provides stable brewing pressure and a constant brewing temperature of around 93 degrees. When the high-pressure boiler heats up to 179 degrees on the stove, the internal pressure rises to 9 bar.
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 cools from 179 degrees to 100 degrees while maintaining 9 bar pressure. The water then passes through the fin heat exchanger, further cooling to 93 degrees.
This allows the water to maintain 9 bar pressure and 93 degrees temperature as it flows through the coffee grounds, resulting in a perfect espresso topped with crema.
The heat plate included with the 9Barista is only suitable for stovetop use. If you wish to use it on an induction cooktop, a separate induction-compatible heat plate must be purchased.
