Two billion cups of coffee are sold daily in a £40bn global industry, but now a controversial documentary showing the plight of growers asks whether there is such a thing as ethical coffee. At the end of the day, every cup we drink relies on exploitation.
Black Gold is galvanising audiences wherever it plays.
