This is a great, super hot, very flavorful, ghost pepper hot sauce.  This sauce has been roasting my mouth for years now!  I like buying real hot stuff like this, and mixing it into my meals in very small quantities, then it lasts a lot longer.  Be warned though, if you use too much of this stuff, it'll ruin your food!  I go through a lot of habanero hot sauce, but this stuff it easily 3 times hotter than any habanero hot sauce I've ever bought.  Just be ready for the heat, or you'll regret it!
