Believe it or not, asking the question of who invented espresso is quite common but not many people know the correct answer.
It was a fellow by the name of Luigi Bezzera who was the owner of a manufacturing business that invented espresso at the turn of the century. All he was trying to do was trying to figure out a way to brew coffee faster. Luigi worked out that if he just added pressure to the brewing process it would speed the whole coffee brewing up. As a result the “fast coffee machine” was invented.
Luigi’s idea of a fast cup of coffee had turned out much better than he anticipated and what he ended up with was a much better tasting cup of strong coffee that also had the advantage of being processed much faster. What Luigi also found was that the quicker way of brewing the coffee allowed the best quality of coffee to be extracted from the beans then he accounted previously.
