First of all, there are three types of Osmanthus oolong:

1. The most common type is the spray type: tea is sprayed with aroma. This is commonly available at the airport and at the tea house for tourists. Because of tea is sprayed with fragrance, so the tea leaf used is of lower cost material too. The fragrance is strong but easily escaped from nostile and cannot feel the depth or aftertaste when drinking it. This is so-called fragrant tea.

2. Tea is directly mixed with dried Osmanthus flowers. Osmanthus flowers are well-distributed even in dry conditions. The fresh osmathus flowers is hard to obtain, and it is easily withered and may developed odd-flavor if it is not handle with care. So, the dried osmanthus flower is easier to handle. But, the flavor is different from fresh osmanthus flower.

3. Finally, the most exclusive type is "fresh osmanthus flower" mixed directly with oolong tea, and the tea leaves naturally absorb the fragrance of fresh flowers. Hojo's Alishan Osmanthus Oolong is this type. It is characterized by a distinctively sweet and refreshing aroma reminiscent of mangoes or peaches.
