Manufacturers’ advice about refrigerating hot sauce:

• Frank’s RedHot manufactures 9 different hot sauces. It recommends refrigerating two of them, Frank’s RedHot Sweet Chili® and Frank’s RedHot® Slammin’ Sriracha® Chili Sauce, after opening. Frank’s says that refrigerating its other sauces keeps them fresher, but is not required.
• On its website, Cholula says you need not refrigerate its hot sauces. However, Cholula does not, put that advice on individual bottles. Also, its site recommends using hot sauce within 6 months after opening. Again, Cholula does not include that advice on the bottles themselves.
• Texas Pete recommends refrigeration for only one of its hot sauces, CHA! , a sriracha hot chili sauce. That means even its garlic hot sauce is shelf stable enough to be kept unrefrigerated. Texas Pete does, however, state that refrigeration will keep its products fresher for longer, contradicting the source that said refrigerating vinegar-based hot sauces was not a good idea.
• Huy Fong Foods makes Sriracha Hot Chili Sauce and Vietnamese Style Chili Garlic Sauce among others. On its site, Huey Fong says that you do not need to refrigerate its products. Instead, you should store them in a cool place. However, the company does not put that information on all of its products.
