Freeze dried tea

Freeze dried coffee does not use cold! Well, it may do, but there is a better way! Freezing coffee may take out water – but I am not interested!
If you reduce air pressure, the temperature at which water boils is depressed! Even a chemistry vacuum pump will get the pressure down enough fro warm water to boil at 30 C – I was shown this 30 years ago!
This temperature will not ruin the taste of tea, so this is what we do! Apply low pressure to the brewed tea.
So we get a concentrated liquor of tea. We could totally dry this off to a powder, but I would tend to go with a tea concentrate, like Camp coffee!
A lot of the world likes a nice drew of tea, and we can give this drink, independent of the local water taste!
