Espresso Machines

"Death by a thousand cuts." When a shot of espresso goes awry, there are what seem to be thousands of factors that contribute to its demise. In other words, it's never just one thing. A barista must account for water temperature, water pressure, water quality, temperature fluctuations, atmospheric pressure, humidity, bean density, and much, much more, as all are taken into account before the beans are even ground for espresso. Thus, the reliability of an espresso machine, which is directly responsible for the application of water to the coffee ground for espresso, is of the utmost importance.
