Now, I know this is a very bizarre question, and I tried to find a correct exchange for this, but it might relate to biology/science as it being our taste buds and everything.
I am so sorry if there is a better exchange for this, but (I hate using this excuse) I'm new to StackExchange, so please be gentle and point me in the right direction.
Now, to meat and bones (Unintended pun; meat...bones...biology hehe), over the last few days I have noticed that after my drink returning to room temperature, it is so much sweeter than it originally tasted.
Hot Tea - I normally only add 1-2 teaspoons of sugar into my tea and it tastes just right, though after taking a sip when it had returned to room temperature, it tastes about 3 or 4 times sweeter than when it was hot/warm. (Milk)
Iced Tea (Bubble Tea) - Just today I had a bubble tea with the smallest amount of sugar possible, it was still too sweet but I stuck with it, and again when it reached room temperature, it was almost unbearably sweet. (No milk)
Slurpee - Again, after returning to room temperature, it is extremely sweet, with it being much lighter with respect to sweetness.
Hot Coffee - Come to think of it, I have also had the same experience with sugared coffee.
Coke - Also, when coke (or any other soft drink) is flat and room temperature, it also produces the same super sweet taste.
So, I tried to think of possible reasons why this happens but, I cannot think of any possible explaination other than magic.
If anyone knows why this might happen, it would be greatly appreciated since I am tripping out trying to figure out why this happens!
