How long can you keep hot sauce in the fridge?

Unopened hot sauce can last for several years in the pantry, but once opened, it can typically be stored in the fridge for about 6 months to a year. The high acidity and preservatives in most hot sauces help them remain safe to consume for a long time, even beyond this timeframe. However, for the best flavor and quality, it's recommended to use it within a year. Always check for changes in appearance or smell before using.
