Why does pee smell after coffee?

Chef's answer
The polyphenols in coffee are absorbed by the digestive tract and put to use, then broken down and excreted in urine. So, if someone drinks a lot of coffee, their urine may contain a high enough concentration of polyphenols and other coffee compounds. This will make it smell like coffee.
