I've heard from the guy at Starbucks that their coffee actually has slightly LESS caffiene than others because the over-roasting of the beans which gives it bitter taste lowers the caffeine level in much the same way the overbrewing of Guinness wipes out excess sugar found in lighter beers. But as long SB coffee tastes stiff, people will think its got more caffiene.

No, what I read was based on studies, not on smell or taste. The idea that over-roasting would reduce the amount of caffeine sounds like barista bullshit to me. I think caffeine content is determined by the type of bean, not the roasting method, and may explain why Starbucks' caffeine content varies from day to day in these studies -- b/c the coffee of the day varies.
