I wasn’t sure if that’s because there’s no caffeine or because there’s alcohol in it. Wasn’t sure if it was a way to make sure it wasn’t stocked with other energy drinks instead of with alcoholic drinks. One cup of coffee also contains around 80 to 100 milligrams of caffeine. To put this into perspective, a 12-ounce can of soda contains only 35 grams of caffeine, and a typical 16-ounce energy drink has anywhere from 160 to 300 grams of caffeine. The bottom line: Adults should stick to less than 400 milligrams of caffeine a day. Teens age 12 to 18 should stay under 100 milligrams. And kids under 12 probably shouldn't have any caffeine at mQSPKN.
