So, back to the question at hand: how long does sun tea last in the fridge? The answer is, it depends on a few things - like how it's stored, and whether you've added any preservatives like lemon juice or sugar. Generally speaking, sun tea can last for around 3 to 5 days in the fridge, but it's always best to err on the side of caution and give it a sniff before you drink it.
Think of sun tea like a freshly picked apple - it's best enjoyed soon after it's made, before it starts to go bad. And just like an apple, sun tea can be affected by things like temperature and exposure to air. So, if you want to keep it fresh for as long as possible, make sure to store it in an airtight container and keep it refrigerated at a temperature of around 40°F (4°C).
Now, you might be wondering, what happens if you leave sun tea out at room temperature for too long? Well, let's just say it's not a pretty sight - bacteria can start to grow, and before you know it, your tea has turned into a science experiment. So, it's always best to play it safe and keep it in the fridge, where it's cool and bacteria-free.
