This tea is EU Certified Organic. It is a high grade of some of the finest and cared for leaves. The difference in grades depends on the quality and size of the leaf. On the higher grades the leaves are quite large, some more than 2 inches. All these teas have a sweet taste you would expect from a quality Tieguanyin. It is easy to get "intoxicated" from the sublime floral aromas. These teas can compete with some of the best Taiwanese oolongs, but with a distinctely spicy mainland China bouquet. They can be infused 4-8 times gongfu style. This is the best way to taste the subtle notes of this thick leaved oolong. Try one or all of them, you won't be sorry. Grown in Anxi, Fujian Province.
