title_body: Why is chicory added to coffee beans while grinding?
upvoted_answer: Chicory was added to coffee in order to stretch the supply of coffee because it was in short supply and expensive. Though it doesn't taste exactly like brewed coffee, chicory has a similar flavor profile and for some the flavor is complementary. Today, chicory use is predominately due tradition, as is the case here in Louisiana where many, especially in the more southern region of the state, prefer their coffee include chicory.
