What is the shelf life of Tabasco sauce?

The shelf life of Tabasco sauce depends on whether the bottle is opened or unopened. An unopened bottle of Tabasco sauce can be stored for up to 5 years in a cool, dark place. Once opened, the sauce can be kept for up to 2 years in the refrigerator or for up to 3 months at room temperature. It is important to note that the sauce will lose some of its flavor and sharpness over time, so it is best to use it within 2 years of opening.
