title_body: Is a Keurig K-Cafe "shot" really an espresso shot?
upvoted_answer: No, sadly it's absolutely not an espresso shot. 
  
  To get a real espresso shot the ideal settings are to have freshly ground coffee into a portefilter basket leveled and compressed using about 15kgf of force. The amount of coffee should be around 14g-18g (for a double shot) as an input, the output should be like 28-36g (we are talking about a tradtional espresso with a 1/2 ratio). All of this should be done under around 9 bar pressure. A Keurig simply doesn't respect any of theses parameters.
