What happens if you drink green tea expired by 1 year?

It's unlikely you'll experience any serious harm from drinking green tea that's expired by a year. However, here's what you might encounter:

Taste and Aroma:

* Less Flavorful: Green tea's flavor and aroma will likely be less pronounced. This is because the antioxidants and other compounds that give it its unique taste degrade over time.

* Bitterness: You might experience a slightly bitter taste, especially if the tea was stored improperly.

Potential Health Benefits:

* Reduced Antioxidant Content: The antioxidant properties of green tea may be diminished, so you might not receive the same health benefits.

* Loss of Other Compounds: Other beneficial compounds, like polyphenols, might also degrade, reducing the overall health benefits.

General Safety:

* No Immediate Risk: Green tea is generally safe to consume even after its expiration date. There are no known toxins that form or accumulate in the tea over time.

* Possible Mold Growth: If the tea was stored improperly in a humid environment, there's a slight chance of mold growth. This can cause an off-flavor and might be harmful if ingested.

Recommendation:

While drinking expired green tea is unlikely to be dangerous, it's always better to enjoy tea that's fresh for the best flavor and health benefits. If you're unsure about the quality, discard it and purchase a new bag.

Here are some tips for storing green tea to maximize its freshness:

* Store in an airtight container: This helps prevent moisture and oxygen from degrading the tea.

* Keep in a cool, dark place: Avoid direct sunlight and heat.

* Store in the refrigerator: For extended storage, the refrigerator can help slow down the degradation process.
