Jamaican Blue Mountain Coffee is the only know coffee to date that has no after taste. Not trying to push my own product, however after many different taste tests- Blue Mountain Coffee has a great flavour no acidic after taste that doesn't leave that itchy or scratchy throat. This after taste is caused by acid in the coffee, based on the location that is the bean grown and the roast. Maybe it is Jamaica's altitude and unique climate that has resulted in this unusual occurrence. The Blue Mountain range is located on the East Coast of Jamaica, this range has the highest peak in the Caribbean which falls along the equator. This provides the Range with a cool climate and moderate temperature changes.
