Tag: Coffee vs mountain dew

An average 8-ounce cup of brewed coffee contains between 95 and 140 milligrams of caffeine, while a 12-ounce can of Mountain Dew contains significantly less, at around 54 milligrams. This stark difference debunks the common myth that soda provides a more potent caffeine jolt than coffee.

A 12-ounce can of regular Mountain Dew contains 54 mg of caffeine, but a standard 12-ounce cup of brewed coffee can contain two to three times that amount. This means coffee is almost always the more potent source of caffeine, ounce for ounce.
