Oolong Tea: Frequently asked questions

What types of Oolong Tea are there and what determines a good product?

The most common types of Oolong Tea are Tieguanyin, Dong Ding and Shui Xian. Other varieties include Baozhong, Jin Xuan and Alishan. Each type has its own unique characteristics depending on the region where it is grown as well as how long it is oxidized during processing (the longer the oxidation period, the darker in color). Some tea connoisseurs even believe that different regions produce teas with their own distinct flavor profiles due to differences in soil quality or climate conditions such as temperature variations between day and night.

The most important factor is the tea leaves themselves. A good Oolong Tea should have a nice balance of floral aroma, sweetness and aftertaste. It must also be well-processed to ensure that it has no astringent or bitter taste.

Who should use a Oolong Tea?

Oolong Tea is a great tea for anyone who wants to drink more green tea, but doesn’t want the caffeine. It can also be used as an alternative to coffee and black teas that are not recommended during pregnancy or breastfeeding.

Based on what criteria should you buy a Oolong Tea?

You should primarily look at the grade of the tea. The best Oolong Tea is made from leaves that are hand-picked, and then naturally dried in the sun. These teas can be very expensive because they take a lot more time, effort, skill and experience to make them right. But if you want quality – this is what you should buy.

When you are looking to buy a Oolong Tea, make sure you check out the quality of material used in making it. The best ones will be made from high-quality tea leaves and natural ingredients with no artificial additives or preservatives. Also look for packaging that is airtight and opaque so as to protect the contents inside from moisture damage while being transported over long distances.

What are the advantages and disadvantages of a Oolong Tea?


Oolong Tea is a great alternative to coffee. It contains less caffeine than green tea and black tea, but more than herbal teas like chamomile or peppermint. The taste of oolong is also very similar to that of coffee without the bitter aftertaste.


Oolong teas are not as well known in the west, so they may be harder to find. They also have a lower caffeine content than black or green tea.
