How long can tea bags last?

The shelf life of tea bags varies depending on the type of tea, storage conditions, and packaging. Generally speaking, the shelf life of tea bags ranges from six months to two years. Black tea has the longest shelf life, and if stored properly, it can last up to two years. Green tea and herbal tea have a shorter shelf life and are best consumed within six to twelve months after purchase.

It should be noted that although tea bags may be harmless after their shelf life, they may have lost their taste and aroma. If you drink expired tea, you may notice differences in taste and quality.
