I’m convinced Sriracha is different in different places. Obviously, different brands have varied heat but the classic one available worldwide is definitely hot, it’s not extreme but definitely hot. I wouldn’t call myself a hot sauce person either but I do enjoy hot foods and condiments, I’d say about average on heat sensitivity. I know several people who just can’t have Sriracha because it’s too hot for them, and it’s easy to make something too hot with a lot of it IMO.
