Since Tabasco pepper plants are sold in most places that sell Bonnie plants it's easy to make your own with whatever amount of vinegar you prefer. When I make my Tabasco sauce I actually soak my peppers in vinegar for several weeks to as long as I need them until I have to make more. The vinegar softens the peppers so that when I put them into a smoothie maker they vaporize, seeds and all. Then I just add more vinegar, some salt, mix it up and I'm done. Super easy to make. McIlhenny goes the extra step of aging them in oak barrels they buy from Jack Daniels so you can't replicate that flavor but you can make it taste pretty darn good.
Xanthan gum is a dealbreaker for me when it comes to hot sauces.
