How long can tea sit at room temperature?

The length of time tea can sit at room temperature depends on the type of tea and how it was brewed. Generally speaking, most brewed teas can be left out at room temperature for up to 24 hours. However, it's important to note that the flavour and quality of the tea will start to decline after a few hours.

Here are some specific guidelines for different types of tea:

- Black tea: Black tea is generally the most stable type of tea and can be left at room temperature for up to 24 hours. However, the flavour will start to decline after about 8 hours.

- Green tea: Green tea is more delicate than black tea and should be consumed within 12 hours of brewing. After that, the flavour will start to become bitter and the antioxidant content will decrease.

- Oolong tea: Oolong tea can be left at room temperature for up to 18 hours. However, the flavour will start to decline after about 12 hours.

- Herbal tea: Herbal tea is generally the least stable type of tea and should be consumed within 12 hours of brewing. After that, the flavour will start to fade and the tea may become cloudy.

It's also important to consider the storage conditions when leaving tea at room temperature. The tea should be stored in a cool, dry place, away from direct sunlight. This will help to preserve the flavour and quality of the tea.

If you're not sure how long your tea has been sitting at room temperature, it's best to err on the side of caution and discard it. Drinking spoiled tea can cause stomach upset and other digestive problems.
