What Is Thai Iced Tea?
Thai iced tea — Cha Yen, ชาเย็น — is a strongly brewed Thai tea sweetened with sugar and condensed milk, poured over ice, and finished with evaporated milk or fresh cream. The color is deep orange. The taste is sweet, cold, and unmistakably Thai. At the market it came in a plastic bag. At home my mother made it in a glass.
Note From Susie
Sawasdee Kha, and Hello.
This was always just there.
Not a special occasion drink. Not something that appeared only at celebrations or at restaurants. Thai iced tea was part of our regular life — at home, at the street markets, wherever we found ourselves on a warm day, which in Thailand is most days. My mother made it at home. The markets had it too, sometimes handed to you in a plastic bag with a straw pushed through the top, the orange color bright through the plastic, condensed milk still swirling at the bottom.
That plastic bag. If you have been to a Thai street market you know exactly what I mean. The drink sealed in, the straw in, the bag twisted closed and handed over. It is one of the most specific things I can picture from those market days — the Cha Yen in a bag, cold and sweet, something to hold while we moved from stall to stall.
At home it was a glass. My mother brewed the tea strong and sweetened it properly and poured it over ice and added the condensed milk herself, the way she wanted it. It was a regular drink. It was simply what we had.
Sweet and cool and completely Thai. That is still exactly what it is.

— Her Hands His EyesWhat Is Thai Iced Tea?
Thai iced tea — ชาเย็น, Cha Yen — is one of the most recognized drinks in Thai cuisine and one of the most immediately distinctive. A strongly brewed Thai tea — made from a blend of black tea and spices including star anise, tamarind seed, and sometimes food-grade orange food coloring that gives it its signature deep orange color — is sweetened with sugar while still hot, then poured over ice and finished with sweetened condensed milk and evaporated milk or fresh cream poured slowly over the top. The condensed milk sinks and swirls through the orange tea before it is stirred, making every glass as visually specific as it is flavorful.
Thai iced tea recipe is distinct from regular iced black tea in several ways: the tea blend itself is specific — Thai tea mix, sold at Asian grocery stores, is a pre-blended combination of Ceylon tea and spices that produces the orange color and the particular flavor that no simple black tea replicates. The sweetness level is higher than most Western iced teas. The condensed milk provides both sweetness and richness that milk or cream alone cannot. And the temperature — served very cold, over a full glass of ice — is non-negotiable.
At street markets across Thailand, Cha Yen is served in plastic bags sealed with a rubber band and a straw pushed through the top. The bag keeps the drink cold as you move. The color through the plastic is exactly the orange it should be. According to the Oxford Companion to Food, tea was introduced to Thailand through Chinese trade influence and has been part of Thai street food culture for generations, with the sweetened iced version becoming one of the country’s most beloved everyday drinks.
At the market it came in a plastic bag. At home my mother made it in a glass. Both were the same drink.
What You’ll Need
Thai tea mix — this is the foundation and it is not substitutable with regular black tea. Thai tea mix is a pre-blended combination of Ceylon black tea, star anise, and other spices, often with food-grade orange coloring added, that produces the specific deep orange color and flavor of Cha Yen. It is sold at Asian grocery stores in bags or loose — Cha Tra Mue is the most widely recognized brand, the one with the gold elephant on the packaging. One brand may be slightly more orange, another slightly spicier — but all Thai tea mix produces a result that a plain black tea cannot approximate.
Water — two cups, just off the boil. The tea brews strong — three to four tablespoons of loose Thai tea mix or two to three tea bags per two cups of water. Steep for five minutes. No longer. Over-steeped Thai tea turns bitter rather than strong, and the bitterness fights the sweetness in a way that is not correct.
Sugar — two tablespoons, stirred into the hot brewed tea while it is still hot so it dissolves completely. The sweetness is part of what Thai iced tea is. This is not a drink that benefits from reducing the sugar significantly — the balance between the sweet tea, the rich condensed milk, and the cold ice is calibrated. Adjust at the table by adding less condensed milk rather than reducing the sugar in the brew.
Sweetened condensed milk — two to three tablespoons per glass, poured over the ice and tea at the end. It provides sweetness and the creamy richness that makes Thai iced tea what it is. It sits at the bottom of the glass and swirls up as it is stirred — that swirling is part of what the drink looks like and part of why it is worth making at home.
Evaporated milk or fresh cream — one to two tablespoons, poured slowly over the top of the finished glass before serving. It floats briefly before being stirred in, creating the layered look of the drink that appears in every photograph of Thai iced tea. Evaporated milk is traditional. Fresh cream produces a richer result. Both are correct.
Ice — a full glass, crushed or cubed. The drink should be very cold. The ice is not a background element — it is what makes the tea Cha Yen rather than just Cha.
VISUAL WALK THROUGH
Step 1. Brew the Thai tea strong and hot.
Bring two cups of water to just below a boil. Add three to four tablespoons of Thai tea mix — loose, placed in a fine mesh strainer or tea sock over a pot or pitcher. Pour the hot water over and steep for five minutes exactly. Do not squeeze the tea leaves — it adds bitterness. Remove the strainer and discard the leaves. The tea should be a deep, rich orange-brown at this stage. While still hot, add the sugar and stir until completely dissolved. The tea needs to be hot for the sugar to dissolve properly — it will not dissolve correctly once the tea has cooled.
Step 2. Cool the tea completely before pouring over ice.
Let the sweetened tea cool to room temperature — or refrigerate it until cold. This step matters: hot tea poured directly over ice melts the ice immediately and dilutes the drink significantly. The tea should be at least room temperature before the ice goes in, and cold from the refrigerator is better. My mother always brewed the tea ahead and kept it cold. That is the right approach — brew a batch, refrigerate, pour over ice when it is needed.
★ Step 3. Fill the glass with ice, pour the cold tea over, then add the condensed milk. This is What Makes the Difference.
Fill a tall glass completely with ice. Pour the cold sweetened tea over the ice — the glass should be nearly full. Then add the sweetened condensed milk: two to three tablespoons, poured slowly over the back of a spoon or directly from the can. It will sink through the orange tea and settle at the bottom, swirling slowly upward. That swirl — orange tea and white condensed milk moving through each other — is the visual that makes this drink immediately recognizable. Do not stir yet.
Step 4. Add the evaporated milk or cream on top. Then serve.
Pour one to two tablespoons of evaporated milk or fresh cream slowly over the top of the drink — over the back of a spoon to keep it floating on the surface for a moment. The layered look of the drink — deep orange below, pale cream above — is part of what Cha Yen is. Then hand it over with a straw and let the person drinking it stir it themselves. Or stir it yourself. Either way, the moment the condensed milk and evaporated milk swirl through the tea is the moment the drink becomes what it is.
Ultamate Thai Iced Tea (Cha Yen) Recipe
Ingredients
- 2 cups water
- 3 tablespoons Thai tea mix
- 1/2 cup sugar
- 1/2 cup sweetened condensed milk
- 1/4 cup evaporated milk
- Ice cubes
Instructions
- Prepare the Tea: Boil 2 cups of water in a medium-sized pot. Once boiling, add 3 tablespoons of Thai tea mix. Stir and let it simmer for about 5 minutes. The tea leaves will release their bold, fragrant aroma, filling your kitchen with a hint of vanilla and spice. After simmering, strain the tea using a fine mesh sieve to remove the leaves, leaving you with a rich, amber-colored brew.
- Sweeten the Tea: While the tea is still warm, add 1/2 cup of sugar and stir until fully dissolved. The warmth of the tea helps the sugar integrate seamlessly, creating a smooth and sweet base for your iced tea. Allow the sweetened tea to cool to room temperature before proceeding to the next step. This cooling period is crucial as it ensures your tea won't melt the ice too quickly, keeping your drink perfectly chilled.
- Mix with Condensed Milk: Pour into a large pitcher once your tea has cooled. Add 1/2 cup of sweetened condensed milk and 1/4 cup of evaporated milk. Stir well until the milks are thoroughly combined, giving the tea its signature creamy texture and sweetness. The condensed milk adds a luscious, velvety consistency, while the evaporated milk enhances the richness without overpowering the tea's flavors.
- Serve Over Ice: Fill tall glasses with ice cubes almost to the top. Pour the creamy tea mixture over the ice, allowing the liquid to cascade through the cubes, creating a beautiful, layered effect. The contrast between the dark tea and the milky swirls is visually appealing and sets the stage for a refreshing experience.
- Garnish and Enjoy: Top each glass with a splash of evaporated milk or whipped cream for an extra touch of elegance. Serve immediately and enjoy your homemade Thai Iced Tea. Each sip offers a perfect balance of solid tea, sweet milk, and refreshing coldness, making it an irresistible treat for any occasion.1/4 cup evaporated milk
Notes

LET’S GET THIS RIGH
Why is my Thai iced tea not orange?
The wrong tea was used, or not enough of it. Thai tea mix contains food-grade orange coloring that is responsible for the drink’s distinctive deep orange color. Regular black tea — even brewed very strongly — will not produce this color. Use Thai tea mix, specifically — Cha Tra Mue is the most widely available. Use the full amount: three to four tablespoons per two cups of water. Less tea produces a paler, less vibrant color.
Why does my Thai iced tea taste bitter?
The tea was steeped too long. Five minutes is the correct steep time for Thai tea mix — beyond that, the tannins in the tea leaves release into the water and produce a bitterness that the condensed milk cannot fully correct. Set a timer. Remove the tea leaves at exactly five minutes. Do not squeeze the strainer — squeezing also releases bitter compounds.
Can I make Thai iced tea without condensed milk?
You can use regular milk or a dairy-free milk, but the drink will taste different — lighter, less rich, less sweet. The condensed milk provides both sweetness and a thick, creamy richness that thinner milk cannot replicate. If you are avoiding condensed milk, use coconut condensed milk as a substitute — it produces a similar richness with a slight coconut note. Regular milk alongside extra sugar is the least satisfying substitute.
How do I make Thai iced tea less sweet?
Use less condensed milk — one tablespoon per glass instead of two to three — and reduce the sugar in the brewed tea by half. The tea itself should still be slightly sweet from the brew; the condensed milk provides the additional sweetness at the glass. Adjusting the condensed milk rather than the brew gives you more control at the point of serving.
Can I make a big batch of Thai iced tea ahead of time?
Yes — and it is the practical approach. Brew a large batch of strong sweetened Thai tea, cool it completely, and refrigerate for up to three days. Pour over ice and add condensed milk and evaporated milk per glass as needed. The brewed tea keeps well cold. Do not add the condensed milk or evaporated milk to the batch — add them fresh to each glass. A batch of brewed Thai tea in the refrigerator means Cha Yen is available whenever it is wanted. That is how my mother kept it.
FLAVOR PROFILE
The color arrives before anything else. Deep orange — vivid, specific, unlike the color of any other tea. In a glass it catches the light. In a plastic bag at a market stall it is bright through the plastic and unmistakable from twenty feet away.
Then the cold — the glass full of ice, the tea already chilled, the condensed milk at the bottom still swirling. Everything about the drink signals cold before the first sip.
The taste is sweet first. Not gently sweet — properly sweet, the condensed milk and the sugar in the brew working together to produce a sweetness that is the point of the drink rather than a background note. Then the tea comes through underneath — strong and slightly spiced, the star anise present without being sharp, the black tea holding the whole drink together. Then the cold, which is its own flavor at this temperature. Then the cream, the evaporated milk or fresh cream sitting over everything and making each sip slightly richer than the last.
It is not a complicated drink. It is not trying to be subtle. It is sweet and cold and orange and completely Thai, and it has been exactly this at every market and every kitchen table where it was made and handed over.
SUSIE’S KITCHEN NOTES
A tea sock — a cloth strainer designed specifically for brewing loose leaf tea — is the correct tool for brewing Thai tea mix. It allows the full amount of tea to steep freely in the hot water without the fine particles that pass through a metal strainer. Thai tea mix can be finely ground and will pass through many standard strainers, ending up in the finished drink as sediment. A tea sock strains it completely. They are inexpensive and available at Asian grocery stores alongside the tea mix itself.
The condensed milk should be poured slowly. If you pour it quickly from any height it will mix into the tea immediately rather than sinking and swirling. The visual — orange tea and white condensed milk in slow motion through each other — requires a gentle pour. Over the back of a spoon is the traditional technique for keeping it from mixing too fast. Take the five seconds to do this correctly. The drink is worth the five seconds.
At the market in Thailand, Cha Yen in a plastic bag is sealed with a rubber band and a straw is pushed through. The bag keeps the drink cold as you walk. It also keeps the ratio of tea to ice exactly right — the ice cannot melt into more space the way it can in a cup. If you want to recreate the market experience at home, use a zip-lock bag, fill it with the finished drink and ice, seal it, and push a straw through. It is exactly what it sounds like and it is exactly right.
My mother made a batch when she made it — not one glass at a time. She brewed the tea strong, sweetened it, let it cool, and kept it in the refrigerator. We poured it over ice when we wanted it. That system is still the right one. Make more than you need. It keeps for three days. And on a warm afternoon — which in Florida is most afternoons — a cold glass of Cha Yen available without any preparation is one of the better things a kitchen can offer.
PAIRING SUGGESTIONS
Thai iced tea belongs alongside spicy food — the sweetness and cold temperature of the drink against the heat of a Thai dish is not accidental. It is the reason Cha Yen appears at every Thai restaurant table and at every market stall alongside the food. For a full Thai meal at home, Thai iced tea pairs with the Tom Yum Goong the way the sweet softens the sour — not competing, correcting. Alongside the Thai beef red curry ,the cold sweetness of the tea cuts through the richness of the coconut milk the way a palate cleanser does, without being one. For a dessert pairing, the Thai pumpkin custard is the natural companion — sweet and fragrant and cold against sweet and cold, the pandan in the custard and the spice in the tea finding each other quietly. My mother had this drink at home and at the market. She had it whenever she wanted it. That is the right approach. Make it. Keep it cold. Reach for it when the day is warm and the food is spicy and the glass is right there.
FAQ
What is Thai iced tea (Cha Yen)?
Thai iced tea — Cha Yen, ชาเย็น — is a strongly brewed Thai tea sweetened with sugar and poured over ice, finished with sweetened condensed milk and evaporated milk or fresh cream. The tea is made from Thai tea mix — a blend of Ceylon tea, star anise, and spices with food-grade orange coloring — which gives it its distinctive deep orange color. It is one of the most recognized drinks in Thai cuisine and a staple of Thai street markets and home kitchens alike.
How do you make Thai iced tea step by step?
Brew three to four tablespoons of Thai tea mix in two cups of very hot water for five minutes. Remove the tea leaves and stir in two tablespoons of sugar while the tea is still hot. Cool the tea completely. Fill a tall glass with ice, pour the cold sweetened tea over, then add two to three tablespoons of sweetened condensed milk — pour slowly so it swirls through the tea. Add one to two tablespoons of evaporated milk or cream on top. Serve with a straw.
What tea is used in Thai iced tea?
Thai iced tea is made with Thai tea mix — a pre-blended combination of Ceylon black tea, star anise, and other spices, typically with food-grade orange coloring added. It is not the same as regular black tea and cannot be substituted for it without changing the color and flavor of the drink entirely. Cha Tra Mue, the brand with the gold elephant on the packaging, is the most widely available and recognized Thai tea mix. It is sold at Asian grocery stores.
Why is Thai iced tea orange?
Thai iced tea gets its distinctive deep orange color from the food-grade orange coloring added to Thai tea mix, combined with the natural color of the strongly brewed Ceylon black tea and spices. The color is specific to the Thai tea mix blend and cannot be replicated with plain black tea. This is the color that makes Cha Yen immediately recognizable — in a glass, in a plastic bag at a market stall, through any container it is served in.
What is the difference between Thai iced tea and regular iced tea?
Thai iced tea uses a specific Thai tea mix blend rather than plain black tea, producing a deep orange color and a spiced flavor that regular iced tea does not have. It is significantly sweeter, with sweetened condensed milk providing both sweetness and richness. Evaporated milk or cream is added on top rather than regular milk. The overall flavor profile — sweet, spiced, creamy, very cold — is distinct from Western iced tea in every dimension.
Can I make Thai iced tea dairy-free?
Yes. Coconut condensed milk is the best substitute for sweetened condensed milk — it provides similar sweetness and richness with a slight coconut note. Coconut milk or coconut cream works in place of evaporated milk on top. Oat milk or almond milk are thinner substitutes that produce a lighter result. The tea itself and the Thai tea mix are dairy-free. The dairy components can all be replaced while keeping the essential character of the drink.
How long does brewed Thai iced tea keep in the refrigerator?
Brewed and sweetened Thai tea keeps in the refrigerator for up to three days in a covered container. Do not add the condensed milk or evaporated milk to the batch — add them fresh to each glass when serving. A batch of brewed Thai tea in the refrigerator means the drink is ready to pour at any time. My mother always kept it this way. Make more than you need. It keeps well and it is always the right temperature when you want it.
