Ounce for Ounce...

Mountain Dew has 4.6 mg of Caffeine per ounce. Coffee ranges from 16 - 25 mg per ounce. Tea Totallers will be surprised to learn they run at about 9 mg, or twice the caffeine of my Dew.
That's Right!

1 Mountain Dew = 1.48 Pepsi
1 Mountain Dew = 1.2 Coca-Cola
4.2 Mountain Dew = 1 Coffee

So, next time you look down your nose at my 20 oz. Morning Dew, remember you have at least 50% more caffeine in your little bitter cup than I have in my sweet, cold, delicious, refreshing Dew.

So back off the lectures about "overdoing" the caffeine!

But Jim you have 3 big cups a day!

Yes, on the average workday I have 60 ounces of Mountain Dew.

If you have 2 of the 7 ounce cups of coffee that day we are even!

Of course, if you are drinking decaffeinated coffee I question your sanity, why drink coffee if not for the caffeine?
