Does chai have caffeine?

Yes — a home-brewed cup of chai has about 50 mg of caffeine from black tea (published figures: 47–55 mg). See chai latte and dirty chai comparisons.

Yes — chai has caffeine, and it comes from the black tea it's brewed with, not the spices. A home-brewed 8 oz cup of chai typically lands around 50 mg, in line with black tea generally. Published figures for black tea vary by source: the FDA lists 71 mg per 12 oz serving (about 47 mg per 8 oz), while Healthline reports a range of 25–110 mg per 8 oz, averaging around 55 mg. A café chai latte runs higher still, roughly 70–95 mg, since it's made from a stronger concentrate.

How much caffeine is in a cup of chai?

Traditional chai — properly called masala chai — is black tea (usually Assam) simmered with milk, water, and whole spices like cardamom, ginger, cinnamon, cloves, and black pepper. The spices add flavor, not caffeine; all of chai's caffeine comes from the tea leaf. That puts a home-brewed 8 oz cup of chai in the same range as black tea generally — around 50 mg is a typical figure, though published black-tea numbers vary by source: the FDA's 71 mg per 12 oz works out to about 47 mg per 8 oz, while Healthline puts black tea at 25–110 mg per 8 oz, averaging roughly 55 mg.

Within that range, what moves the number is how much tea goes into the pot, how long it simmers, and how strong you brew it. A quick steep with a light hand on the tea leaves lands toward the low end; a long-simmered, tea-heavy batch (the kind used for chai concentrate) lands toward the high end. See our full masala chai recipe and chai vs masala chai guide for how the traditional version is actually made.

Does a chai latte have caffeine?

Yes — a café chai latte has caffeine, and typically more of it than a home-brewed cup. Café chai lattes are built from a pre-made tea concentrate rather than fresh-steeped tea, and that concentrate is stronger per ounce. Per Starbucks' published beverage nutrition data, a Classic Chai Tea Latte runs about 70 mg at 12 oz (Tall) up to about 95 mg at 16 oz (Grande). See our full chai latte breakdown for how it's made and how it compares to traditional masala chai.

So a chai tea latte — and a chai tea latte made at a different chain — does have caffeine; the size and the concentrate's strength are what push it above a home-brewed cup, not a different kind of tea.

Chai vs coffee, black tea, green tea, matcha, and espresso

Use the calculator above to compare any drink by the cup or across a full day — its "black tea" setting is the same range brewed chai falls in — or check the static reference table below:

Three things stand out. First, brewed chai and plain black tea occupy the exact same range — chai's spices season the tea, they don't change its caffeine. Second, café chai lattes and dirty chai sit well above home-brewed chai, mostly because of concentrate strength and serving size, not a different caffeine source. Third, a "chai" made with rooibos instead of true tea is naturally caffeine-free, since rooibos isn't from the tea plant at all.

Dirty chai: how much caffeine when you add espresso

A dirty chai is a chai latte with a shot of espresso added; a filthy chai uses a double shot. Combining Starbucks' published chai latte figures (about 70–95 mg) with an espresso shot (roughly 60–80 mg, in line with the ~63 mg average espresso figure used across this site), a dirty chai commonly lands around 130–175 mg total — squarely in coffee territory. See our full dirty chai latte recipe for how to build one at home.

What changes chai's caffeine

• Tea-to-water ratio. More loose tea (or more tea bags/sachets) per cup pulls out more caffeine, the same way a stronger pour-over has more caffeine than a weak one.
• Steep/simmer time. Caffeine extracts quickly from black tea; a longer simmer (the method used for chai concentrate) pulls more of it out than a quick steep.
• Concentrate vs. fresh-brewed. Café concentrates and bottled chai bases are formulated to be strong per ounce, since they're diluted with milk at the point of service — that's the main reason a café chai latte outranks a home-brewed cup.
• Milk dilution. Milk doesn't remove caffeine, but a milkier pour (more milk, less tea/concentrate) spreads the same caffeine across more liquid, which can change how strong a cup tastes without changing its total mg.
• Decaf or rooibos base. Swapping in decaffeinated black tea or rooibos (which was never tea to begin with) removes most or all of the caffeine — see below.

Rooibos and decaf "chai": caffeine-free alternatives

If you want the spice blend without the caffeine, two options get you there. Rooibos "chai" swaps the black tea for rooibos, an herbal tisane from a South African shrub that isn't related to the Camellia sinensis tea plant — it contains 0 mg of caffeine naturally, spices and all. Decaf chai uses decaffeinated black tea instead; decaffeination removes most, not all, of the caffeine, so a decaf cup carries a small residual amount rather than being truly caffeine-free.

Chai, caffeine, and L-theanine

Because chai is built on real tea, it also carries L-theanine, an amino acid concentrated in tea leaves. Published research has looked at how L-theanine and caffeine interact: Kelly and colleagues (2008, Journal of Nutrition) reported that the combination was associated with changes in alpha-band brain activity and attention-task performance compared with either compound alone. That describes what the study measured, not a promise about how any individual cup will make you feel — responses vary by person and by how much you drink.

Is chai's caffeine a lot?

For most healthy adults, a single cup of chai (around 50 mg, up to roughly 70 mg on the higher end of published black-tea figures) or even a full café chai latte (70–95 mg) is a modest share of the general daily reference published for healthy adults — the U.S. FDA has cited about 400 mg per day as a level not generally associated with negative effects for most healthy adults. That reference covers everything you drink in a day, not any single cup, so it's worth counting chai alongside coffee, other tea, and any other caffeinated drinks. People who are pregnant, caffeine-sensitive, or managing a health condition should talk to a healthcare provider about what caffeine level is appropriate for them.
