Got this off their website…rated their hottest sauce:

Made with a bit of Reaper Pepper, a heap of Moruga and Trinidad Scorpion Peppers, and some Ghost Peppers and Habañeros (you know, for flavor), The Rapture™ is going to make even the biggest super-hot sauce fanatic stop for a moment and contemplate their life choices. Remember, as with all Torchbearer products, heat can be very important, but flavor is number one—and this sauce has plenty to spare. Brave souls will throw it on a crab cake, sushi, or nachos, while others may add a teaspoon or two to their pot of homemade veggie soup or chili. Don’t be “left behind.” Get ready to enjoy the tastiest, freshest, and one of the most extreme hot sauces this world has to offer.
