A dirty chai is a chai latte with a shot of espresso dropped in: spiced tea concentrate, steamed milk, and coffee in one cup. "Dirty" is the espresso. Order it anywhere that makes both drinks, since it is an assembly, not a recipe; a double shot makes it a "filthy" or "extra dirty" chai. It exists because chai's spice and espresso's roast flavor genuinely work together, and because a regular chai latte does not carry enough caffeine for a work morning.
What is actually in the cup
| Component | Brings |
|---|---|
| Chai concentrate or brewed masala chai | Black tea plus cinnamon, cardamom, ginger, clove; most cafe versions are pre-sweetened |
| Steamed milk | Body, any milk works; oat holds spice well |
| 1 espresso shot (2 for filthy) | Roast depth and most of the caffeine |
Caffeine, honestly
The espresso shot adds about 63mg per USDA data, on top of whatever the chai base carries from its black tea, which varies by concentrate and typically lands a chai latte in the low double digits to near 100mg at chain strength. So a single dirty chai usually sits in the 130 to 160mg zone at a chain, similar to a latte with an extra shot. Chain-specific chai numbers are in our caffeine database with sources; for context, the FDA cites 400mg a day as generally not associated with negative effects in healthy adults.
Making one at home
Heat and froth a cup of milk with 2 to 3 oz of chai concentrate (or strong-brewed masala chai plus honey), then pour a fresh espresso shot on top; moka pot or Aeropress coffee substitutes fine per our no-machine espresso guide. Concentrate sweetness varies wildly between brands, so taste before adding anything.

FAQ
What does dirty mean in a dirty chai? The espresso. A chai latte is "clean"; adding a shot makes it dirty, and two shots make it filthy.
Does a dirty chai have more caffeine than coffee? Usually a bit less than a large drip. One shot plus the tea base lands around 130 to 160mg at chain strength, versus roughly 140mg for a 12 oz drip at the USDA average rate.
Does a dirty chai taste like coffee? The spice leads and the espresso sits underneath as roast depth. If you want the coffee louder, order it filthy.
