For those who insisted to me that Mountain Dew had more caffeine than a cup of coffee, I present the following:

Caffeine per 7oz cup of coffee (source):

• Drip coffee: 115 – 175 mg
• Espresso: 30 mg
• Colombian Espresso: 40 mg
• Brewed/Pressed: 80 – 135 mg
• Instant: 65 – 100 mg
• Decaf, brewed: 3 – 4 mg
• Decaf, instant: 2 – 3 mg

Caffeine per 12oz serving (source):

• Mountain Dew: 55.2mg

Arguably, a 24oz bottle of Mountain Dew has more caffeine (110.4mg) than some 7oz cups of coffee, but ounce for ounce, the only coffees that have less caffeine than Mountain Dew are decaffeinated.
