Does espresso taste burnt?
The main cause of sour, bitter, and burnt flavors in espresso is over-extraction and under-extraction. With over-extraction the coffee becomes overcooked and releases unwanted flavors; it becomes harsh, bitter, and burnt. With under-extraction too few of the good flavors end up in the cup; it becomes weak and sour.

Why do espresso shots go bitter?
The more the espresso sits the more it becomes bitter. The emperature of the espresso falls rapidly within seconds of brewing and crema disappears within about 10 minutes. Coffee oils continue to oxidize and the flavor compounds break down leading to a bland or even bitter espresso.

Why is my espresso shot sour?
