Does Hot Sauce Ever Really Expire? - Tasting Table
Briefly

Hot sauce can last one to two years if unopened and stored in a cool, dark place; once opened, refrigerate it to prolong freshness for up to a year.
Different hot sauces have different shelf lives. Ingredients like vinegar and fermentation contribute significantly to their longevity, but proper storage is essential for safety.
Indicators of spoiled hot sauce include changes in color, such as darkening, and sediment accumulation at the bottom, which signal that it may no longer be safe to consume.
Once opened, hot sauce should be refrigerated and tightly sealed to prevent bacterial contamination and ensure it remains flavor-rich for months.
