4) Espresso Technology

A good espresso is a sublime experience: rich, sweet, and wonderfully caffeinated.

But, who woke up one morning and thought to themselves, ‘I’m going to build a contraption that forces a tiny amount of super hot water with incredible pressure through a bed of very finely ground coffee’?

Well, the fact is, the first “espresso” machine built 150 years ago was awful in almost every way. Worst of all, if you gave that coffee to anybody on the street, nobody would say it’s even an espresso!

But, over the decades, problems begat solutions that begat more problems that culminated in espresso machines like Eversys that produce gorgeous espressos at just the push of a button.

And it’s got me wondering: what is the perfect espresso machine? How far can we go?

But, before clicking play, be warned: this story gets explosive and bloody!
