Oolongs are mid-range in oxidation, between green and black teas. Our loose leaf oolong selection contains premium Chinese oolongs, including a traditional tie guan yin and milk oolong blend. Medical research suggests that oolong aids in weight loss through fat burning mechanisms, beyond that of green tea. Wu long tea, well known for weight loss, is simply a different way of spelling oolong in english. Our whole leaf oolongs are available in bulk and sachets.
