Oolong tea is semi oxidized, giving it a unique taste different from green tea and black tea. Ito En's Unsweetened Golden Oolong Tea is brewed from a unique blend of whole oolong tea leaves - flowery, fragrant Huan Jin Guei "Golden Cinnamon", and hearty, ripe Tieguanyin "Iron Goddess". Enjoy its robust and clean taste, with no added flavors or colors, not from tea powders or concentrate.
