There is an art to pulling a perfect shot of espresso

The ideal shot takes 18 to 22 seconds to pull. I have to make sure that the espresso grounds are packed to just the right firmness, that the right amount of water filters through, and control the temperature. If a shot isn’t perfect, I won’t serve it. This is what happens to your body when you drink coffee every day.
