12 oz bag- 156mg of Caffeine! #Workflow is a blend of 100% Arabica, Colombian, Excelso, and Guatemalan Beans. It is a 75% dark and 25% light roast. The light roast is what gives #Workflow that extra 25% kick of caffeine. Both are wet-processed. Mixing these two beans gives you the best of both worlds: the caffeine, and the bold taste of the dark roast.
