Yes espresso shots do eventually die but they can be revived with a few simple steps.
The key to reviving a shot is to understand why it has gone off in the first place and then taking the necessary steps to restore it.
What Causes an Espresso Shot to Die?
An espresso shot can die for a variety of reasons the most common of which are stale ingredients improper tamping over-extraction or temperature fluctuation.
Stale ingredients are the result of using espresso beans or grinds that are aged and will lack the flavor aroma and crema of a freshly brewed shot.
Incorrect tamping which is the process of packing the espresso grounds into the portafilter can lead to uneven extraction and unsatisfactory results.
Over-extraction which is when the espresso is left to brew for too long can lead to a bitter and unpleasant tasting shot.
Finally temperature fluctuation which is a common issue in some commercial espresso machines can cause espresso shots to come out too hot or too cold and will lead to a poor cup of coffee.
