Bio Tea is a total new type of green tea. It has been particularly developed to be brewed in cold water as well as a traditional hot brewed tea. This is a significant break through, because commercialisation of a cold water brew tea had been considered extremely difficult for many centuries. It is cultivated and processed by optimising full advantage of natural energies such as sun and water. Bio Tea is named after natural biorhythm. Now you can enjoy a delicious cold water brewed green tea any time.
