With this hot weather, it's hard to imagine adding more heat to your daily agenda, but that's exactly what customers are asking for at Red Robin.

The Colorado-based burger chain is now featuring one of the world's hottest peppers on two different cheeseburgers.

What's one of the world's hottest peppers? The ghost pepper definitely qualifies.

According to Wikipedia, the Scoville scale is a measurement of the spicy heat (or piquancy) of a chili pepper.

A typical jalapeno pepper is between 3,500 and 8,000 Scoville heat units. By comparison, a ghost pepper is estimated between 855,000 and 1,000,000 heat units.

KJCT asked Grand Junction residents if they'd be willing to try a burger with that kind of spice.

"I personally wouldn't be, that sound like a heck of a bad day right there but I do know some more brave individuals who would definitely be more willing," said James Colby.

"A bite yes, the whole thing, not necessarily, but I'd try it," said Christine DeCoster.

Red Robin has two different burger styles featuring the ghost pepper this summer.

The "Fiery Ghost" style has ghost pepper sauce. The "Cry Baby" style includes ghost pepper ketchup, which is a little bit sweeter and not quite as spicy.

General Manager of the Grand Junction Red Robin, Jason Gehrken, said that the ghost pepper burgers are selling better than they expected.
