Coffee prices slipped further in September 2013, with the ICO composite indicator falling 4% to its lowest level since April 2009. The sharpest decline was observed in Robustas, which dropped by 6.6% to their lowest monthly average in nearly three years. At the end of coffee year 2012/13, total production is estimated at 145.2 million bags, 9.6% higher than the previous year. A decrease is estimated in the production of Other Milds, mostly due to damage from coffee leaf rust in Central America, although this has been more than compensated by increases in the other three coffee groups, especially Colombian Milds.
