Espresso. All the flavors, and the chemicals--including the caffeine--are concentrated in espresso.

1 serving of espresso
I'd be inclined to say it depends on who is making the coffee... if it is mee, it could possibly be a tie! HA HA... seriously though, due to the high concentration of espresso, it would seem logical that it would have a much greater concentration of caffeine as well. However, since the espresso serving is so much smaller you have an evening effect. For instance, according to Wikipedia a shot of arabica espresso will have roughly 40 mg of caffeine, where a standard strong drip cup of coffee will have roughly 100 mg. Again you have the variable of the size of the serving. Also noted is the light roast vs. the dark roast as the roasting process will diminish the concentration of caffeine.

Surprisingly enough, a small cup of espresso has only about 60% of the caffeine in a regular cup of coffee. The explanation is below.
Making espresso means extracting maximum flavor from coffee using minimal hot water. That requires forcing water through the coffee under high pressure. The result is an emulsion of flavorful and aromatic oils combined with other chemical elements and suspended gas bubbles, giving you the concentrated flavor, velvety texture, and crema (foam) that distinguish true espresso. (Notwithstanding espresso's reputation, a shot of espresso contains only about 60 percent of the caffeine in a regular brewed cup--even though both use about the same amount of ground coffee--because the water is in contact with the grounds for such a brief time, ideally about 25 seconds
It's a common misnomer that espresso has more caffeine, but coffee does. It's because of serving size and length of extraction. Espresso has a stronger flavor, and I imagine that's the reason many Americans think it has more caffiene.
"A cup of drip brewed coffee has about 115 milligrams of caffeine, an espresso (and percolated coffee) about 80mg, while instant coffee has about 65mg of caffeine. Decaffeinated coffee is not totally caffeine free, containing about 3mg of caffeine. A can of Coca-Cola has about 23mg of caffeine, Pepsi Cola 25mg, Mountain Dew 37mg, and TAB 31mg. Tea has about 40mg of caffeine, while an ounce of chocolate contains about 20mg." From: http://www.didyouknow.cd/coffee.htm...
Esspresso, because when they make an esspresso, it's compressed and it gets more caffine out that way.
Espresso,because it`s more concentrated.
American Coffee. Even though Espresso tastes stronger, it has less caffeine.
The difference is in the preparation. Steam passes through the grounds too fast to extract as much caffeine.
I found a website, http://www.ciod.info/products.html,... where the caffeine is the lowest in the world, the healthiest coffees.
