Which is quite a shame, actually. Oolong tea is a wonderful choice for making a milk tea.

What is oolong milk tea?

Oolong milk tea can be made in different ways. The most popular one may be boba or bubble tea, made with tapioca pearls. This type originates from Taiwan, and it’s very popular. Bubble tea can be made with any type of tea and comes in hundreds of flavors. The other type of oolong tea is similar to regular milk tea – made with pure tea leaves, milk and sugar. Although boba milk tea can be both hot and cold, cold is the more usual way of serving it. On the other hand, regular milk tea will taste better hot. Extra idea: Another great way of making a milk drink with oolong tea is making an oolong tea syrup first, then mixing it with milk and ice cream to make a unique milkshake. Oolong tea is a semi-oxidized type of tea that can be more or less oxidized. Less oxidation will make oolong more similar to green tea, and more oxidation will move it closer to black tea. Oolong tea is special for its unique range of aromas – from very fruity to very floral. Some oolong teas can mimic flavors in such a way you may even think there are other natural or artificial flavors present in your tea leaves. However, not all oolong teas have a strong flavor – some are more delicate and may not be the best choice for making milk tea. For making the best oolong milk tea, choose teas with more body, with darker color and stronger flavor.

Caffeine level in milk tea

Caffeine in a cup of tea depends on many factors – from tea plant to growing conditions, harvesting and processing methods, and brewing. Oolong tea can have caffeine content lower than green tea, or even higher than some black teas. Expect moderate levels of caffeine.
