Record coffee harvests in Brazil, the biggest grower, are compounding a global glut of arabica used by Starbucks and Dunkin' Donuts.

Brazilian farmers will reap 50.8 million bags in 2013, a record for a so-called low-crop season, according to the median of nine analyst estimates compiled by Bloomberg. The harvest reached 55.9 million 132-pound bags in 2012, an all-time high for a peak year. Output usually drops in alternate years because of growing cycles.

About 72 percent of the country's crop was arabica this year and the rest robusta, typically used in espressos.
