A lot depends on the other ingredients! It's a good place to start, but use common sense.
The Hot Sauce 101 contains links to approved recipe from extension services. Again, use common sense when substituting. Peppers can be interchanged to what's in the recipes with no problems.
Fermenting is totally different than making a straight cooked hot sauce. Fermentation will bring down the pH level without the use of vinegars. For those that don't want to ferment, some other method of getting the pH down to safe levels is employed....usually with the aid of vinegars.
Sauces with vinegar can be cooked, bottled and immediately consumed as the pH is immediately in a safe zone. Fermentation takes weeks/months to get the peppers into a safe pH zone, but once the ferment is in the safe pH, no further vinegar needs to be added. It can be blended, cooked, bottled as desired.
