Which has more caffeine: a cup of coffee, a cup of tea, or a glass of Coke?
We started our quest by entering “caffeine content” into the Yahoo! search box. That turned up a slew of sites offering doses of information. We headed to a page from Holy Mountain Trading Company that answered your question. According to the site’s caffeine index, coffee has the most caffeine with 47-164 milligrams per 5 ounce serving.

A single serving of black tea (5 oz.) can have anywhere from 25 to 110 milligrams of caffeine, while a single serving of Coca-Cola (12 oz.) measures in with 46 milligrams. However, when you break it down to caffeine per ounce, tea handily beats Coke. Since we always like to check our work, we also paid a visit to the Coffee Science Information Cent
