* BAD news for coffee junkies. The South African Tea, Coffee and Chicory Association chairman has issued a press release warning of price increase in the wake of a 100 percent increase in the price of unroasted coffee beans over the past 10 months. The association cites the world coffee growers’ Opec-style Retention Scheme and devastation of crops in Indonesia and Brazil as reasons for a 100 percent rise in world coffee prices to $1,60 a pound. To this must be added the devaluation of the rand, says the association.
