How to Make Chai Concentrate at Home for Lattes All Week
Share
A café chai latte is mostly milk plus a few ounces of strong, sweet, spiced tea. Make that spiced tea yourself in one 30-minute batch and you can pour a chai latte in under two minutes every morning. Here is how to make chai concentrate at home with loose-leaf black tea and whole spices, plus the ratios for hot, iced and dirty chai.
The idea is simple: brew tea and spices much stronger than you would drink them, sweeten, strain, chill. Then dilute with milk when you serve.

Ingredients
Spices
- 2 cinnamon sticks
- 10 green cardamom pods, lightly crushed
- 8 whole cloves
- 1 teaspoon black peppercorns
- 2 star anise (optional)
- 2 inch (5 cm) piece fresh ginger, sliced
Tea and liquid
- 4 1/2 cups (1.1 liters) water
- 1/4 cup (about 20 g) loose-leaf black tea, such as Assam, or a spiced masala chai blend
Sweetener
- 1/2 cup (100 g) packed brown sugar, or 1/3 cup (110 g) honey or maple syrup
- 1 teaspoon vanilla extract (optional)
- A pinch of salt
If you use a ready-spiced masala chai tea, you can halve the whole spices and still get a bold result.
How to make chai concentrate at home
- Toast the spices. Put the cinnamon, cardamom, cloves, peppercorns and star anise in a dry saucepan over medium heat for 1 to 2 minutes, until fragrant. Do not let them smoke.
- Simmer. Add the water and ginger, bring to a boil, then lower the heat and simmer gently, covered, for 15 minutes. The spice flavor builds here, not in the tea step.
- Steep the tea off the heat. Turn off the heat, stir in the tea and steep for 5 to 7 minutes. Steeping black tea longer than this tends to add bitterness rather than strength.
- Strain. Pour through a fine-mesh sieve, pressing the spices lightly. You should have about 3 1/2 cups (830 ml); some water evaporates during simmering.
- Sweeten. While hot, stir in the sugar or honey, vanilla and salt until dissolved.
- Cool and bottle. Let it cool, then pour into a clean glass jar or bottle and refrigerate.
Why it works
Whole spices release their flavor slowly and need simmering; tea releases flavor fast and turns harsh if boiled for long. Splitting the process into a spice simmer and a short tea steep gives you strong spice and strong tea without the bitter, tannic edge that ruins many homemade concentrates.
Serving ratios: hot, iced and dirty chai
| Drink | Concentrate | Milk | Extra |
|---|---|---|---|
| Hot chai latte | 1/2 cup (120 ml) | 1/2 cup (120 ml), steamed or heated | Dust with cinnamon |
| Iced chai latte | 1/2 cup (120 ml) | 1/2 cup (120 ml), cold | Full glass of ice |
| Lighter chai | 1/3 cup (80 ml) | 2/3 cup (160 ml) | Good for afternoons |
| Dirty chai | 1/2 cup (120 ml) | 1/2 cup (120 ml) | 1 shot espresso |
| Chai cold foam topping | 2 tablespoons (30 ml) | 1/4 cup (60 ml) cream or milk | Froth and spoon over iced coffee |
For a hot latte, heat the concentrate and milk together in a small pan or the microwave, or warm the concentrate and add steamed milk. Our guide on how to froth milk covers foam without an espresso machine.
Dirty chai with real espresso
A dirty chai is a chai latte with a shot of espresso. A bold coffee holds its own against the spices: Italian Roast brings smoky, dark chocolate depth, and if you want it in the evening, Decaf Espresso is water-process decaf roasted dark for espresso. For the full drink and its story, see our dirty chai latte recipe.
Make it your own
Choosing the tea
Use a strong black tea that can stand up to milk and spices. Our Masala Chai is a bold, spiced loose-leaf blend in the Indian tradition, so it gives you a head start on flavor. English Breakfast, a blend of African and Indian black teas, makes a plainer, malty base if you want to control every spice yourself. For an earthier twist, Chaga Spice Chai combines Assam black tea and chaga mushroom with cinnamon, ginger, cardamom and vanilla.
Spice and sweetness variations
- Extra warming: double the ginger and peppercorns.
- Sweeter, softer: add an extra cinnamon stick and the vanilla.
- Fennel and nutmeg: add 1 teaspoon fennel seeds to the simmer and grate nutmeg on top when serving.
- Unsweetened: skip the sugar in the batch and sweeten each cup to taste. Unsweetened concentrate is also handy for baking.
- Lower caffeine: replace half the black tea with rooibos, or use a decaf black tea.
Dairy-free
Oat milk is the closest match to dairy in a chai latte because it froths well and has natural sweetness. Almond milk is lighter; coconut milk adds richness. Our article on the best milk for coffee compares how each behaves when heated.
Storage and troubleshooting
Keep the concentrate in a sealed glass jar in the fridge. Recipe developers commonly give up to two weeks, but flavor is brightest in the first week, and fresh ginger fades over time, so this recipe is sized to be finished in about seven days. Shake before pouring, since fine spice particles settle.
To keep it longer, freeze it in ice cube trays. Two or three cubes melted into hot milk, or dropped into cold milk for an iced chai, make a single serving.
| Problem | Likely cause | Fix |
|---|---|---|
| Bitter or astringent | Tea steeped too long or boiled | Steep 5 minutes off the heat next time |
| Weak spice flavor | Spices not simmered long enough, or old ground spices used | Use whole spices and simmer the full 15 minutes |
| Tastes watery with milk | Too little tea, or less water evaporated than expected | Use more tea or serve at a 2:1 concentrate-to-milk ratio |
| Cloudy after chilling | Tea compounds cloud when cold (normal) | Harmless; it clears when heated |
| Sour or fizzy smell | Spoiled | Discard and make a fresh batch |
Chai concentrate FAQ
How long does homemade chai concentrate last?
About a week in the fridge for best flavor; some recipe writers keep theirs up to two weeks. Freeze it in cubes for longer storage.
What is the ratio of chai concentrate to milk?
Start at 1 to 1 for a café-style latte, then adjust. Use more milk for a lighter drink.
Can I use tea bags instead of loose-leaf tea?
Yes. About 8 to 10 standard black tea bags replace 1/4 cup of loose tea. Loose leaf usually gives a fuller flavor.
Does chai concentrate have caffeine?
Yes, because it is made with black tea. A serving made with half concentrate generally contains less caffeine than a cup of brewed coffee; see coffee vs tea caffeine for typical ranges.
Can I use ground spices?
You can, but they make the concentrate gritty and cloudy. If you do, use about one third the amount and strain through a paper filter.
