The 15 Most Caffeinated Cities in the U.S.After creating "Which U.S. states have the most number of Starbucks?" I decided to make an infographic for overall coffee consumption and caffeine intake in the US that wasn't just specific to Starbucks. I found a survey that The Daily Beast published and I made a chart based on it. Guess which U.S. cities are most caffeinated? I'm a little confused by how they decided the ranking by looking at the result, but as long as Seattle takes the top, I'm satisfied. Is your city in the top 15?
