Obviously, the main selling point of this sauce is the heat, and to be clear - this is potent stuff. On a good day, this is pretty much the hottest thing I can eat and still enjoy whatever I'm eating.
That said, this sauce also has a bold, savoury flavour with strong caribbean influences, quite apart from the capsaicin level, and it would be a mistake to take it for a one-trick pony based on the bottle.
