The new coffee will be offered starting Wednesday By Mia Len • Luke Sharrett/Bloomberg via Getty Images Dunkin' prides itself on fueling Americans to keep them "running." Well, brace yourself, because their fuel is apparently getting stronger. The Massachusetts-based chain announced the launch of its new "Extra Charged Coffee," which it says contains 20% more caffeine than its Classic coffee and debuts Wednesday. The company said a medium Extra Charged Coffee will be offered at a special $2 price through Jan. 26. The company also announced two additional coffee products: Dunkin' Midnight, which it calls its darkest roast ever; and Explorer Batch, a "medium roast featuring dark berry notes."
