By "depth", I mean extra nuance, variety of flavors, and a multi-dimensional quality. Also, the taste improves as the brew cools. Espresso does, indeed, have less caffeine than lighter roasts but that refers to the caffeine content of each bean. When espresso is brewed, a very fine grind is used as well as a high proportion of coffee to water. So, a cup of espresso has a higher concentration of caffeine than a comparable amount of regular coffee.

I saw a wonderful lapel pin that, regrettably, I didn't buy. It said, "Death Before Decaf".
