With coffee prices at a 30 year high Sheila Dillon traces the money we pay for a cup along the supply chain and also hears how it raises big questions for Fairtrade.Recently the price for coffee on the world market broke through the important $3.00 barrier. Just a few years ago prices were as low as 60 cents. Speculation from investors is one reason, but other factors like growing demand for coffee in Brazil and China look like creating a long term spike in prices. So what does this mean for growers and what will this mean for us? Will we start to taste the difference as roasters in the UK are forced to source different and cheaper beans?This price spike also raises big questions for the Fairtrade model. Current prices are way above Fairtrade's minimum price, so do coffee growers still need Fairtrade? Producer: Dan Saladino.
