The company said a single CO2 charger can produce between 4-8 double or triple shots of espresso, a number that depends more specifically on the volume of water added or the duration of extraction, as opposed to grind and tamp.

The 58-millimeter brew head is made of stainless steel. A pressure gauge on the face of the device allows users to monitor the level for pressure profiling. In either case, a metal knob on the side of the Xbar is used for throttling pressure downward. With the cartridge, a paddle on the top of the Xbar allows users to control the upward ramp of pressure. When using a bike pump, the pump is in control of the upward ramp of pressure while brewing.

One is a Shrader valve, compatible with a wide variety of electric or manual bicycle pumps, and the other accepts disposable 8-gram CO2 gas cartridges, such as those used for small seltzer-makers. Two valves on the side of the Xbar allow for the different pressure sources. The Xbar espresso maker from a Chinese manufacturer has surpassed $80,000 on Kickstarter.Ĭurrently charging through Kickstarter is a new portable espresso brewing device from China called the Xbar, which uses either a gas cartridge or a bicycle pump to exert water pressure.
