I've been told by Wikipedia.com that espresso has less caffeine than drip. However, when I check on Mayoclinic.com, I read that they are about the same. What's going on here; does drip coffee indeed have more caffeine than a pulled espresso (assume two shots)? Boss lady at work and a few coworkers say that it's because of the volume of coffee in the basket (drip) versus coffee in the portafilter (espresso) that does it. I always thought it was the extraction process itself (pressure & hot water for espresso versus hot water for drip) that gave espresso the leading kick. However, the volume thing has a good point to it.
What I'm getting at is: I'm an egotistical fool and I may have just been proven wrong. I just want to make sure that I really am wrong before stomping my feet and going to a corner to pout... :D
