Abstract
Abstract Origin and coffee grades are major factors determining the price of coffee beans. Jamaica Blue Mountain coffee achieves among the highest prices in coffee trading due to its assumed high quality. In this contribution we show the first chemical composition analysis of Jamaica Blue Mountain using LC-MS methods. In particular differences in chlorogenic acid regioisomer distribution were observed for Jamaica Blue Mountain coffee if compared to reference coffees sheding light on the chemical basis of grading systems in coffee.

Keywords
Coffee, chlorogenic acids, polyphenols, LC-MS
