Replying to Coffee Drinkers: Help Me.

Blah blah, black coffee I'm so fucking cool, make fun of my sugar if you're that big of a tool.


So now on to business.  I have a super-convenient Keurig brewer and I have a question about a new type of coffee I just started drinking.  It's 'Dark Magic expresso blend by Green Mountain' and despite being so bold and dark, with a kick ass amount of caffeine, I find that I have to use significantly less sugar to achieve my desired taste.  Does anyone know why it's like this?
