This fascinating three-part documentary series traces the unique and volatile history of coffee. Coffee first reached Brazil via French Guiana in the 18th century. Slaves were imported to work on the plantations and their suffering brought wealth to the coffee barons, part of Brazil's new peerage. Mass marketing of coffee in the US led to a cycle of high prices, over production and a dramatic fall in price, which caused untold misery to the poor of the coffee producing countries. Today, coffee drinkers are starting to question the origin of their coffee and the living conditions of those who produce it.
