Segawa Seicha proudly recommends this new product. Sun Rouge is a rare Japanese tea that also changes color. It is a mysterious Japanese tea that changes color. When brewed, it is an ordinary green Japanese tea, but when lemon, lime, or soda water is added, it instantly changes to a beautiful red color! This is due to the action of anthocyanin, a black tea ingredient. This natural color change makes this tea visually pleasing. It is also delicious as a cold tea!
