Does Jasmine Green Tea Have Caffeine?

If you’re hoping jasmine tea is a gentle, caffeine-free option, check the label first. Jasmine green tea has caffeine, because the jasmine is added to real green tea.

Why does jasmine green tea have caffeine?

The caffeine comes from the tea leaves, not the flowers. Twinings lists the ingredient in its Jasmine Green Tea as “green tea scented with jasmine flowers.”

A 2022 study in Molecules describes how traditional jasmine tea is made. Tea leaves are repeatedly mixed with jasmine blossoms (Jasminum sambac), the mixture is spread out, reheated and scented, and then the flowers are separated from the tea. The tea in that study was green tea. Scenting adds aroma. We found no source saying it changes the caffeine.

How much caffeine is in jasmine green tea?

We couldn’t find a figure measured on jasmine green tea itself, so the best guide is green tea in general. These sources give a sense of the range:

Source	Caffeine	Serving
Mayo Clinic, brewed green tea	About 29 mg	8 oz
Twinings FAQ, green tea	19 to 45 mg	1 tea bag in 7 oz
Lab study of 20 commercial teas (range for the white, green and black teas)	14 to 61 mg	6 or 8 oz
Mayo Clinic, brewed coffee (for comparison)	About 96 mg	8 oz

Twinings doesn’t list a separate number for its jasmine blend on the pages we read, and its FAQ says its values are for guidance only. Its figures vary with the blend, the amount of tea in the bag, the tea’s origin and the steep time. For its other green teas, see Twinings green tea caffeine.

By these figures, a cup of jasmine green tea would likely land somewhere in the same range as other green tea. That is our reading of the sources, not a measured result.

What changes the caffeine in your cup?

• Steep time. Twinings says the longer tea steeps, the more caffeine is extracted. The lab study also found that steep time affected caffeine levels.
• How much tea you use. Two bags in one mug will give more than one.
• The tea itself. Twinings notes that growing conditions, harvest timing and soil all change caffeine in the leaf.

How do you know if a jasmine tea is caffeine free?

Read the ingredients. If “green tea,” “tea” or “black tea” is listed, it has caffeine. A drink made without tea leaves is an herbal infusion. Twinings says herbals such as peppermint and camomile are naturally caffeine free because they don’t come from the tea plant. In the lab study, herbal teas had no detectable caffeine.

Some labels say only “jasmine tea.” The Molecules study used green tea as its base, but we can’t tell you what other products use, so check the ingredient list.

Want less caffeine but the same flavor? Decaffeinated green tea exists, though it isn’t completely caffeine free. See our guide to decaf green tea.

How much caffeine is too much?

The FDA cites 400 mg a day as an amount not generally linked to negative effects for most adults. It also notes that people vary widely in how sensitive they are, and that body weight, medications and some conditions can change what counts as too much. If you’re pregnant, trying to become pregnant, breastfeeding or taking medicine, ask your health care provider about limiting caffeine.
