Fernet Branca

Fernet Branca is a liquor made from herbs. How does one make a liquor from herbs? And why would you do so?

ANSWER PERSON RESPONDS: It’s an aromatic bitter, like Campari or Angostura. The herbs are soaked in a base of a distilled spirit (in this case distilled from fermented grapes, like brandy) to impart their flavor to it, and aged over a year in oak. It’s used as an after dinner drink or probably more often as an ingredient in mixed drinks. Why? Why do people flavor anything they eat or drink?
