Is Darker roast means less caffein?

It is true, However there are a number of ways to increase/decrease the caffine in the cup you drink. Such as brew method, green beans, roast colour, on and on and on

The dark roasts I drink always seem to have plenty of caffeine. The caffeine also seems easier to taste through the coffee. The extremely dark, charcoal-tasting roasts however do seem to have noticeably less caffeine, and even I added some crushed caffeine to them like I've done to coffees that don't have enough I would still strongly dislike their taste.
 
Caffeine does burn off with roasting, but so do other things. Interesting that if you measure caffeine by weight in dark roasts, you get more caffeine than in light roasts. Moisture evaporates faster than caffeine burns out. If you measure by volume, you get less because when you roast beans, they expand.

I've heard a number of people say they can taste caffeine in Starbucks. Caffeine is extremely bitter - anyone who has chewed a NoDoze can tell you that.

But is the bitterness in Starbucks really the caffeine or is it over-roasting and rancid oils?

I agree

"javahill" thank you for clarifying this, to be honest, I was of the crowd that just said darker has less caffine knowing you are dealing in the actual volume of grinds that fill the portafilter. You have taken a scientific approach to this and I have to give you a thumbs up on your analisis and you are very much right on.
