Before everyone jumps in, either do your own Google or check out my post on this thread.
As a toxicology, i always taught that espresso had the same caffeine per liquid measure, but since you drank a smaller portion, you actually received less caffeine

As I understand it, light roast has more caffeine but is more bitter as well. Dark roast is less bitter, but less caffeinated. I like a medium roast.

What baristas at coffee houses tell me is the reverse: the longer the beans are roasted, the lower the caffeine level. And the darker beans are the ones that are roasted longer.

Less caffeine, I'd guess. Heat may destroy the caffeine molecules ( a complicated organic structure), and the longer the coffee beans are exposed to a heat source, the more molecules will be decomposed.

Caffeine is reduced by roasting, so the longer you roast the less there is.
Tea has more caffeine than coffee.

@meJess A chemistry graduate student once told me that the caffeine in tea and the caffeine in coffee are different stereoisomers. That is, the molecules have the same chemical formula but the atoms are arranged in one shape in tea and in another shape in coffee. The isomer is tea is not as readily absorbed by the body as the one in coffee.
I have some experience that verifies this. I dislike coffee and drink only tea. But years ago, someone offered me some "Irish coffee" -- coffee, Irish whiskey, and sweet cream. I had some at night -- the whiskey was so strong that i did not even taste the coffee! lol. But when I tried to get to sleep that night, I felt a buzz that kept me awake. On the other hand, I regularly drink black tea at night and have no problem falling asleep afterward.

No! Light roast has more caffeine, roasting takes out the caffeine to a extent
