LONDON, Nov 13: Coffee drinkers in Brazil, America, Eastern Europe and the Middle East are expected to down more arabica beans in their brew in the coming year as cheap prices attract additional demand for the higher spec product. A surplus from top grower Brazil after two successive bumper crops helped drag arabica prices to a four-and-a-half-year low this week, which is likely to prompt roasters to increase the use of the bean in their blends.
