Sriracha and standard Chinese red pepper sauce are staples that should always be available.
However, if heat is the goal without compromising flavor, nothing beats Bailiff Brutality.

It claims to be a salsa, but don't be fooled. It's hotter than Dave's Insanity by volume. This sauce is insidious. The chunks of roasted pepper and tomato trick you into putting a couple spoonfuls on your burrito. The oil base delays the burn... allowing you to eat more. At about 10+ minutes after eating the "salsa", the Capsicium filled oil finally starts to hit the nerves and it hits you with at least a half hour of increasing pain. This sauce gives you time to think about the situation you put yourself in before hitting you with the pepper heat. And then it does it to you again six hours later.
But the best part - which you're not going to believe - is the it really does have an outstanding roasted tomato/pepper flavor. I like it for the taste, not the insane heat.
The hot sauce I have in my desk at work is
Arizona Pepper's organic harvest jalapeño pepper sauce.
Contains red ripened jalapeño peppers, vinegar and salt and tastes exactly how I imagine hot sauce would.
I also like the habanero version from the same brand for its smoked flavor.
Both are sugar free which is important for me and taste amazing without being overwhelming.
1/22 is [National Hot Sauce Day][https://m.facebook.com/nationalhotsauceday/], btw.
Lesser known brands are always good too, but I can never go wrong with this holy trinity.
Lately, I've been absolutely in love with Trader Joe's brand habenero salsa. It's perfect on everything.
I love trying out all the sauces at Firehouse subs, but the one I buy for home is Cholula.
I prefer a bit of sweetness in my sauce. Sour.. not so much.
It has a great kick to it, but also a really deep and unique flavour. At university I went through a bottle a week!
Also hijacking this to ask for a good BBQ sauce? :)
Original for Ribs and General BBQ
Tennessee Red for pulled pork
If you want something more special, check out this sauce from my local famous bbq joint. It's slightly spicy, and they've been around going on 100 years. Hard to get a seat in there.
Mojo Picon from Canary Island is also great. Not quite hot, but Papas arrugas con mojo picón is a gratis dish.
Tabasco Chipotle for Tacos, can't eat them without it now.
