Dunkin' Brands (DNKN) really wants you caffeinated today, which is National Coffee Day.

The restaurant chain will be giving away a free medium-sized coffee with the purchase of any size above small. Interestingly, the offer of free coffee perfectly captures what's happening right now in the business of coffee. Dunkin' is effectively at war with McDonald's (MCD) in the business of selling coffee. The Golden Arches continues to offer sharp discounts on its various hot and iced coffees to drum up badly needed business. Meanwhile on the higher-end of the spectrum, Starbucks (SBUX) continues to concoct sugary iced bombs that fetch upward of $6 each.

Nevertheless, Dunkin' Brands CEO Nigel Travis remains bullish on coffee. And in fact, he thinks that Dunkin just flat out makes better coffee than McDonald's and that should bode well amidst the coffee wars.

"I don't think the coffee business is any more competitive that it has ever been, but it's very competitive," Travis told TheStreet in an interview. "You can buy a coffee from McDonald's, or you can buy the real stuff from Dunkin."

Starbucks is a holding in Jim Cramer's Action Alerts PLUS Charitable Trust Portfolio. Want to be alerted before Cramer buys or sells SBUX? Learn more now.
