Caffeine by McDonalds Iced Coffee Size. 1  Medium (16 floz): 133mg. 2  Large (22 floz): 200mg. 3  Extra Large (32 floz): 320mg.
According to the Australian Government agency Australian Broadcasting Commission; http://www.abc.net.au/quantum/po... A standard 250ml cup of tea (iced or hot) contains about 27 mg of caffeine; (varies from 8 to 91 mg) A 375ml can of Coke contains a fixed amount of 38mg of caffeine. So, doing the comparison math on a standard 285ml (US 9.6 fl.oz) glass of home iced tea and Coke then: 1  A 285ml glass of iced tea = 30.8mg of caffeine on average, but could be as high as 103 depending on the tea variety and brew time. 2  A 285ml glass of coke = 28.9mg of caffeine. A study of the vast majority of research into caffeine in beverages puts tea ahead of coke for % of caffeine content. Note: Iced green tea has only half the caffeine content of black tea. 20.7k Views Â· 7 Upvotes Â· 6 Upvotes
