Jasmine tea is a scented tea traditionally made by blending green tea leaves with blossoms from a jasmine plant.

Its popularity both in Asia and abroad has much to do with jasmine tea health benefits and the drink's fragrant, delicate aroma.

What Is Jasmine Tea?

Jasmine tea is a flavored or scented tea. When scented teas are made, traditional tea leaves from the Camellia sinensis bush are infused with flowers, fruit, spices, oils, extracts, or other ingredients to provide additional flavor. Jasmine tea is usually made from green tea leaves or leaves that have not been fermented. But the tea can also be made from black tea leaves (that have been fully oxidized), oolong tea leaves (partially oxidized) or white tea made from new growth buds and young leaves.

As a result of the added scent, jasmine tea has a flavor that most people describe as delicate and sweet. According to some sources, the most famous traditional jasmine tea comes out of the Fujian region of China where it is made with jasmine blossoms. Commercially produced jasmine teas may be made with jasmine oil or another flavoring. 

You'll see different types of jasmine tea advertised online. These include ​jasmine pearl tea, which is hand rolled tea blended with jasmine blooms or jasmine milk tea which is brewed jasmine tea that has been blended with milk.

Caffeine in Jasmine Tea

Many people who enjoy this drink want to know if they'll get a boost of energy after drinking a cup. Does jasmine tea have caffeine? In most cases, it does. But the amount of caffeine in jasmine tea depends on the leaves that were used to make it.

  • Jasmine green tea will have a modest amount of caffeine. Traditional green tea has about 35 milligrams of caffeine per cup.
  • Jasmine tea will have more caffeine if it is made with black tea leaves. Traditional black tea contains approximately 50-90 milligrams of caffeine per cup.
  • Jasmine tea will have less caffeine if it is made with oolong tea leaves. Oolong tea contains about 30 milligrams of caffeine per cup. 
  • Jasmine tea made with white tea may have as little as six milligrams of caffeine per cup (some tea drinkers assume that white tea is decaffeinated) but can have more depending on the kind that you buy.

The actual amount of caffeine in your cup of jasmine tea will depend on a few factors, such as how the tea leaves were processed, where the tea leaves come from, and how you prepare your tea. For example, tea bags usually provide more caffeine than whole tea leaves. Also, steeping the tea longer will give you a more caffeinated beverage.
