Does Green Tea Lose Its Quality Over Time?

Green tea has always been studied and proclaimed as an excellent source of antioxidants and health benefits, can it stand the test of time? We explore the topic to find out whether green tea itself goes “bad”.

Does Green Tea Go Bad?

Green tea can last for quite a long time–up to two years without losing most of its flavor and health benefits. However, it should be stored properly. The same goes for other tea in general. The following tips should be followed to ensure that your green tea remains fresh:

  • Keep it in an airtight container. Keeping the tea away from air helps maintain its flavor and freshness.
  • Store it in a cool, dry place away from moisture. Moisture and high temperatures can affect the quality of the tea.
  • Make sure to reseal the bag or container tightly after use. This helps to keep any air or moisture out and lock in the flavor.

Signs That Green Tea Has Gone “Bad”

Unlike with certain food items, there’s no obvious way to tell if tea has gone bad. However, there are still a few signs to look out for:

  • If you notice an off-smell or taste, this is an indication that the tea has gone bad. The smell should be fresh and grass-like.
  • If it has a bitter taste, it may be an indication of age.
  • A loss of color can indicate that the tea has been exposed to light or air for too long.


In conclusion, green tea won’t necessarily go bad, but it can lose its quality over time. Proper storage is key to locking in the freshness and taste of the tea. If you notice any strange smells or tastes, it’s best to replace the tea with a fresh batch.
