Here is a smart portable espresso maker that can grind beans, boil water, extract coffee and froth milk anywhere. The PortaPresso works with your smartphone to get the job done. Simply fill it with fresh beans and water to get started. This espresso maker holds up to 57g of coffee beans.
The PortaPresso has a built-in LCD screen. It not only gives you control over temperature, strength, and amount of froth but also remembers your settings. Expected to ship in April.
