Expresso is a misspelling of espresso, which refers to the strong, pressure-brewed coffee. The use of expresso in place of espresso occurs most often in spoken English, but it occasionally turns up in written contexts—for example:
For their Christmas market, families can look forward to a Wiggles jumping castle, expresso coffee at $1, free express knife sharpening and a gold coin donation BBQ. [Southern Courier]
It’s equiped with an expresso machine, entertainment system, eight sleeping spaces and an area for massage and recovery. [The Province]
