He has taken the time to research and create a graphic that takes us through the many popular drinks that contain Caffeine (excluding Tea). Colas, drip coffee, Starbucks, Einstein Bros, the Energy Drinks and many more top brands. As well, Randy noted key items in the chart, like coffee half life in the human body is 4.9 hours and ‘the jitters’ set in at 300mg of caffeine.

Fun for this particular poster is that he took the time to do a ‘Making-of. It covers how he collected data, what software he used to build the infographic and even his notes in his moleskin along the way. I enjoyed his parts on where the data came from and his first few attempts at the graphic till he got it just right. I would say he had a winner here. Maybe there will be enough interest for him to end up doing a poster, which he mentions is under consideration. Also under consideration is looking over this poster before you buy your next drink now that you have the facts.
