If you wish to enjoy the best of Colombian coffee, then try the Supremo bean. Often when grading the quality of beans from various region it is based on the attitude and location of the region. The Colombian Supremo is graded because of its size and is and is the largest of the bean size picked off the tree. A tree may only yield about a pound per year. Both the Supremo and Excelso (smaller coffee bean) come off the same tree.
