The jasmine used for tea is almost always Jasminum sambac, commonly called Arabian jasmine. A second species, Jasminum officinale (common jasmine or poet’s jasmine), is also used in production, but sambac dominates commercial jasmine tea, especially the Chinese varieties most people encounter. Out of more than 200 jasmine species in the world, these two are the only ones routinely used to scent tea leaves.
Jasminum Sambac: The Primary Tea Jasmine
Jasminum sambac is a tropical plant grown widely across Asia, Africa, and the Americas. You may see it called mogra in India or sampaguita in the Philippines. It produces larger, often double-petaled white flowers with a rich, sweet, intensely floral scent. That boldness is exactly why tea producers favor it: the flowers contain high concentrations of the aromatic compounds benzyl acetate, linalool, and indole, which together create the unmistakable jasmine tea fragrance.
Sambac is the species at the heart of Chinese jasmine tea production, particularly in Fuzhou, the city recognized by the UN Food and Agriculture Organization as the most important jasmine tea production center in China. Fuzhou’s climate is ideal for growing sambac, and the tea scenting method was first developed there more than 1,000 years ago.
How Jasminum Officinale Compares
Jasminum officinale, native to Iran and Central Asia, is the other species used in tea. Its fragrance is lighter, more ethereal, and often described as fresh and green, with none of sambac’s heavy sweetness. It thrives in temperate climates and is widely cultivated across Europe, Central Asia, and China. Its scent peaks during summer and the flowers are typically harvested at night, when fragrance release is strongest.
Some tea drinkers prefer officinale’s subtlety, but most commercial jasmine teas use sambac for its more powerful aroma. If you buy jasmine tea from a Chinese producer, you’re almost certainly getting sambac-scented tea. Officinale is more common in teas from other regions or in specialty blends.
How Jasmine Flowers Scent the Tea
Jasmine tea isn’t brewed from jasmine flowers. It’s regular tea, usually green tea, that has absorbed the fragrance of fresh jasmine blossoms through a labor-intensive layering process. Fresh buds are spread evenly over tea leaves in a controlled environment, then left undisturbed overnight. As temperatures drop, the buds naturally bloom and release their fragrance directly into the tea leaves.
After several hours, the tea is gently turned to ensure even scenting and prevent moisture buildup, and the spent flowers are removed. For everyday jasmine tea, this might happen once or twice. Premium grades go through six to nine rounds of scenting, each time with a fresh batch of flowers. Research published in the journal Foods confirmed that aroma freshness, concentration, purity, and persistence all intensify with each additional round. The first two rounds make the biggest difference, but the final rounds add a refined quality that distinguishes high-grade jasmine tea from ordinary versions.
What Creates the Fragrance
The characteristic smell of jasmine tea comes from a specific group of volatile compounds that transfer from the flowers to the tea leaves during scenting. Linalool contributes the core “jasmine” note. Benzyl acetate and a compound called hexenyl benzoate add fruity and floral layers. Indole, despite being pungent on its own, rounds out the fragrance at low concentrations. Nerolidol brings a fruity-floral quality, and germacrene D adds a faint woody undertone.
Chinese tea researchers have even developed a “jasmine tea flavor index” based on five of these compounds to measure scenting quality. Linalool in particular has been studied for its calming effects: research on jasmine tea aroma found that linalool can influence autonomic nerve activity and mood, which may partly explain why jasmine tea feels relaxing to drink.
Health Benefits of Jasmine Tea
Because the base is typically green tea, jasmine tea carries all the benefits of green tea’s polyphenols. A cup contains 15 to 60 mg of caffeine depending on steeping time and the base tea used. The catechins in green tea, particularly one called EGCG, have been linked to improved blood sugar control, heart health, and oral health. Reviews of multiple studies suggest green tea may increase metabolism by 4 to 5 percent and fat burning by 10 to 16 percent, which translates to roughly 70 to 100 extra calories burned per day.
The antioxidants in jasmine green tea help neutralize free radicals, and regular consumption has been associated with lower risk of heart disease and mental decline. The jasmine fragrance itself adds a mild calming benefit that plain green tea doesn’t provide.
Toxic Plants That Are Not True Jasmine
Several plants with “jasmine” or “jessamine” in their common name are not true jasmine and should never be used for tea. The most dangerous is Carolina jessamine (Gelsemium sempervirens), a yellow-flowered vine native to the southeastern United States. Every part of this plant is highly toxic. Its alkaloids cause sweating, nausea, muscular weakness, dilated pupils, convulsions, and respiratory failure. Star jasmine (Trachelospermum jasminoides) and night-blooming jasmine (Cestrum nocturnum) are also unrelated to true jasmine and not safe for consumption.
If you’re foraging or growing jasmine for tea, make sure you have a plant from the Jasminum genus. The safest approach is to purchase Jasminum sambac from a reputable nursery.
Growing Tea Jasmine at Home
Jasminum sambac is a tropical plant that grows in USDA hardiness zones 9 through 12 and tolerates only occasional light frost. It needs a warm, humid environment and does well in mildly acidic to mildly alkaline soil. In cooler climates, it grows happily in containers that can be brought indoors during winter. Give it full sun, consistent moisture, and something to climb or trail over.
The flowers open in the evening and are most fragrant overnight into early morning. To scent your own tea at home, pick fresh buds just before they fully open, layer them with loose-leaf green tea in a sealed container, and let the tea absorb the fragrance overnight. Remove the spent flowers the next day. Repeating this process with fresh buds two or three times will produce a noticeably more aromatic result, following the same principle that commercial producers use at a larger scale.
