An International Tea Moment has a very interesting review up on 'The Implications of Roasting'. The Eco-Cha 3 Pack comes with an unroasted, a lightly roasted, and a heavily roasted tea. This review takes you through the three types and compares the flavor profile of different roasts. Have a read to learn which roast is your 'cup of tea'. See the great photo below from An International Tea Moment of these three different teas. 

"My appreciation for Oolongs has grown exponentially over the past few years, and these examples only reinforced that appreciation. There's an oolong for every mood. The heavily roasted Dong Ding for the morning, the Shan Li Xi for a mid afternoon pick-me-up, and the light, sunny Jin Xuan to end your day with a smile."
