Yes, it's hot. See-through-time-and-space hot. Unless you're a chili-head you have no business messing around with this sauce. If you find Tabasco sauce hot, you should expend copious amounts of effort to avoid Dave's Insanity Sauce. While this sauce is hot, it lacks much of the bright, fruity flavor common to Desert Pepper XXX. This sauce tastes more like the peppers were first roasted before being sauced. Or, perhaps the sauce has some liquid smoke or similar ingredient in it.

While I enjoy the heat of Dave's Insanity Sauce, I like the flavor of Desert Pepper XXX better for most situations.
