Not the guy you responded to, but I also love hot sauce. I usually stock franks, yellowbird's red jalapeño sauce (forget the name), and cholula or Valentina if I don't feel like paying for it. I also had this really awesome green hot sauce from El Pato brand, but I haven't ever seen it again. Hopefully someday!

Vinegar tends to be too forward. I go for the stuff you'll find in a Mexican market or "ethnic" aisle of a grocery store. Peppers being an ingredient higher than most others beyond water catch my eye. Melinda's is alright, though I've seen them branch out quite a bit from their more humble beginnings.

I don't like vinegary too much (or smoke/fermented flavor etc), I like El Yucateco Red*.

Though it is a bit expensive for a tiny bottle. So I made a few big bottles trying my own spin* from garden habaneros (orange) and liked how it turned out.

* I see the key ingredients: distilled white vinegar, citric acid, xantham gum and tomato paste EDIT: carrots is another trick, IIRC I fried mine with onions and bell peppers

Ah, a fellow Melinda's enjoyer! I love they're Ghost Pepper sauce in particular (though it's fairly mild for a Ghost Pepper sauce). My only complaint with Melinda's, is that they consistently use too much carrot in their sauces. But otherwise they're really great!
