Homemade Spiced Chai Syrup for Lattes and Coffee
Make your own homemade spiced chai syrup with ginger, cardamom, and mandarin. Rich, aromatic, and perfect for crafting café-style chai lattes at home.
This homemade spiced chai syrup brings together black tea, fresh ginger, and warming spices like cardamom, cinnamon, and clove, balanced with a touch of vanilla and mandarin. The result is a smooth, aromatic concentrate that stirs easily into hot or iced milk.
With winter rolling in, we naturally crave deeply warming comfort drinks. Spiced chai lattes are extremely popular, yet every supermarket chai tea bag I have tried fall short of that rich, aromatic depth and are hugely disappointing.
This syrup delivers a concentrated, café-quality flavour that’s easy to make at home — and just as easy to make in bulk and bottle up as a thoughtful homemade Christmas gift.
Ingredients for Homemade Spiced Chai Syrup
Black Tea
Provides the base bitterness and tannin structure that balances the syrup’s sweetness. You can use loose-leaf tea or tea bags — most tea bags contain around 2 grams of tea, but check the label if unsure. It goes to say that you should use the best quality tea you can here. Low quality black tea usually results in grey flavourless water.
Brown Sugar and Maple Syrup
Sweeten and thicken the syrup while adding mild caramel depth. Adjust to taste if you prefer it less sweet.
Fresh Flavours
Fresh Ginger
Adds heat and brightness that keeps the syrup from tasting flat. Scrub but don’t bother peeling if the skin is clean.
Mandarin Zest and Juice
Provides a clean citrus lift that brightens the syrup and complements the warm spices. I use mandarin because it feels tied to winter and the festive season, but oranges work just as well.
Lemongrass
Adds a subtle citrus-herbal freshness that balances heavier spices. Roughly chop and lightly crush the stalk before simmering.
Vanilla Pod
Softens the spice intensity and gives the syrup a more luxurious feel. Vanilla extract can be used in a pinch.
Dried Spices
The spice blend is highly customisable. This balance is my preference, but you can easily adjust it to suit your taste. I love the licorice and aniseed notes, so I tend to go heavy on the star anise. I’d recommend trying this blend because it’s awesome, but feel free to omit anything you’re not fond of.
The key is to use enough of the spices you include. Too little, and the syrup won’t have the depth needed for the flavour to come through in the finished latte.

Step-by-Step Instructions
Toast the spices
Place the cinnamon, cardamom, cloves, peppercorns, star anise, fennel, allspice mace, and turmeric in a small, heavy-based saucepan. Toast over medium heat for about 2 minutes, shaking the pan occasionally, until fragrant.
Prepare the ginger and lemongrass
Rinse the ginger thoroughly and trim any rough ends, but there’s no need to peel it. Roughly slice it or chop it up. There is no need to precisely chop it here.
For the lemongrass, cut off the dry tip and root end, then peel away the outer layer if it feels tough. Lay the stalk flat on your board and gently crush it with the back of a knife or rolling pin — just enough to split the fibres and help the citrus oils infuse into the liquid.
Simmer the base
Add 1 litre of water along with the sliced ginger, lemongrass, and the toasted spices. Bring to a gentle boil, then reduce to a low simmer. Leave uncovered for 30–35 minutes, topping up with a little water if the level drops too much.
Look for a deep amber colour and a warm, spiced aroma — this signals proper extraction.
Reduce and sweeten
Keep the pan on a low simmer and continue cooking until the liquid reduces to about 450–500 ml. Stir in the brown sugar, maple syrup, and a pinch of salt, letting everything dissolve fully.
Add the tea and aromatics (off the heat)
Remove from the heat. Add the black tea (loose-leaf or tea bags), vanilla pod and seeds, mandarin zest, and mandarin juice. Cover and let infuse for 10–15 minutes, stirring once or twice to ensure even steeping.
Strain and adjust
Pour the mixture through a fine sieve or muslin-lined strainer into a clean jug or bowl, pressing gently to extract every drop. Taste and adjust — add a touch more sugar for sweetness, a squeeze of mandarin for brightness, or a splash of water if it’s thicker than you prefer.
Bottle and store
Transfer the syrup into a sterilised glass bottle or jar and seal. Keep refrigerated for up to 4 weeks. Shake before using.
How to Use Homemade Spiced Chai Syrup
For a hot chai latte, stir 2–3 tablespoons of syrup into a mug of steamed or foamed milk. Adjust to taste depending on how strong or sweet you like it. A spoonful in coffee adds a nice warmth but without overpowering it.
For iced chai, mix the syrup with cold milk and plenty of ice, or combine it with sparkling water for a light chai soda.You can also use the syrup to add chai flavours to baking, such as spice cakes, muffins, or granola, or stir a little into a poaching liquid for fruit like pears or apples.

Notes
Substitutions
- Sweeteners: Use all brown sugar for a heavier caramel profile or all maple syrup for a lighter, more aromatic sweetness.
- Tea: Any strong black tea works; English Breakfast or Ceylon are reliable if you don’t have Assam
Flavour Variations
- Citrus swap: Replace mandarin with orange for a rounder, more classic chai flavour, or use lime for a brighter, sharper edge.
- Extra warmth: Add a slice of fresh turmeric, a few coriander seeds, or a pinch of nutmeg for a deeper, earthier finish.
- Floral twist: A few rose petals or a drop of orange blossom water stirred in at the end gives a softer, more fragrant note
