Well I discovered this on accident one day when I forgot that I made tea. So I come downstairs in my robe and discover my tea brewing along side my stainless steel stove. I go over take out the bag and have a sip. The tea was colder than normal, but it tasted much better. Due to the fact that the teas temperature was reduced, the acidity from the orange was cut down and also diminished some of that powerful orange taste. After doing this I decided to make some more to see if it was coincidence, it wasn’t though.
