As someone not from the U.S., this thread confused me at first and I had to look it up.
What tripped me up is that sriracha is the name of a type of sauce, not a trademarked brand. It’s similar to how many companies can make “ketchup”. In contrast, Tabasco Sauce is a registered brand, so only one company can sell a sauce called Tabasco.
Because of that, several companies produce sriracha. The one most people associate with the name in the U.S. is Huy Fong Foods (the “rooster” bottle, often simply called Sriracha). But it’s just one brand among many, like Underwood Ranches Sriracha (made by the former pepper supplier mentioned in the story).
So when the OP says “the Sriracha guys screwed over their supplier”, they are talking specifically about Huy Fong, not the sauce style itself.
