While it's not the primary or predominate flavor component, such as with Tabasco (which is what I think you might be referring to), there is vinegar in there as acetic acid is the 4th or 5th ingredient in Tapatio. Acetic acid is the pure version of the sour/acidic component in vinegar. White vinegar, for example is typically around 5% acetic acid.
