Mychai is an innovative tea maker concept which allows you make your favorite teas on the go. No matter what you like, simply open and load the device with your favorite leaves and select one of four tea categories displayed on top. Yes, this smart device divide tea into four different categories, and each category has its own perfect brewing time, for example, 2 mins for green/white/yeallow tea and 3 mins for oolong tea. Then, drop it in 1-2 cups of water and it will automatically heat the water to ideal brewing temperature. After the water reaches the desired temperature, the hatch will open – exposing leaves to the hot water and starting brewing process. After certain minutes (depending on the category of tea you select), hatch will automatically open and the tea is ready for you to enjoy.
