I don't think you can get much more caffeine from roasting technique. To get more caffeinated beans, you use the much cheaper low altitude Robusta coffee. Even then, I don't know how you double the caffeine without adding it.

I would think after the nicotine and cigarette fiasco, companies would be super sensitive about artificially adding to the addictiveness of their product. However, it is suspicious.
