It is not an espresso. The temperature and pressure are lower than an espresso machine. The results would be considered analogous to more American style coffee. Meant to be drunk from a full mug (~177ml to ~298ml), etc.

It's marketed as a coffee machine that makes a single cup with a single pod at a time.

(Apparently you can tweak a Keurig to approach an espresso, but it's not the default).
