Example Input: This is more than just a tea, drinking a cup is like a beautiful experience. It has a multi-dimensional flavor, it really does. I never considered myself a tea drinker, but I ordered it once at a Starbucks and was hooked ever since. On special occasions or even when I am down, I treat myself to a cup of this warm and delicous tea.
