Black Coffee: Black Coffee is a 2007 Canadian documentary film examining the complicated history of coffee and detailing its political, social, and economic influence from the past to the present day. The film details how coffee is the eighth most traded legal commodity in the world. It is also the fourth most valuable agricultural commodity. However, only one cent of a $2 cup of coffee goes to the grower.[1] This inequality has helped shape the history of continents and the Cold War.
