What is Thai Tea? Defining a Unique Beverage

Thai tea refers to a sweetened black tea infusion flavored with spices and herbs. Its distinguishing orange-reddish color comes from food coloring. While “Thai tea” is used colloquially to describe this drink, its formal Thai name is cha ron.

The base of Thai tea is high-quality black tea, most often the Assam variety from India and Sri Lanka. This black tea brings a rich, malty flavor and supplies caffeine. The tea leaves are blended with distinctive Thai spices, including star anise, crushed tamarind, and orange blossom flowers. The result is a hearty black tea balanced by bright, citrusy aromas.

Thai tea stands out from other tea beverages like chai or bubble tea. Unlike chai, Thai tea does not contain milk or masala spice blends. And while it can be served chilled like bubble tea, Thai tea is brewed using tea leaves rather than powder and contains no tapioca pearls. The unique infusion process and addition of food coloring give Thai tea its signature reddish-orange hue.

The Evolution of Thai Tea in Thailand

Thai tea is deeply intertwined with the culture and cuisine of Thailand. Its roots can be traced back to the mid-19th century when King Rama III began importing black tea during Thailand’s Bowring Treaty with Britain. The Chinese population in Thailand, many of whom worked as traders or as laborers for the East India Company, likely introduced spices like star anise to flavor the black tea.

Drinking Thai tea soon became embedded in Thai culture. The drink was traditionally served during family gatherings and celebrations. Vendors selling icy glasses of Thai tea became fixtures at Thai markets and shops. As Thai tea gained popularity internationally, its status as a national symbol and point of pride grew for Thais. Today, Thai tea can be found on menus at restaurants worldwide as an ambassador of Thai cuisine and culture.

What’s Actually in Thai Tea? A Look at the Ingredients

Authentic Thai iced tea starts with a base of strong black tea. Traditional Thai tea uses a specific type of indigenous black tea called Bai Miang, but Assam black tea is more commonly used outside of Thailand.

The tea leaves are simmered for a prolonged time to extract maximal flavor and tannins, which gives Thai tea its characteristic orange hue when milk is added. The ratio of tea to water is much higher than typical black tea.

Condensed or evaporated milk provides a creamy texture and orange color. Traditional recipes use full-fat dairy, but low-fat or skim milk are common substitutes. Sweetened condensed milk has the most intense flavor.

Sugar or simple syrup balances the tannic tea and also thickens the texture. White sugar or cane sugar is the most common. The sweetness level varies, but Thai tea is usually quite sweet.

Spices like star anise, crushed tamarind, and orange flower water provide exotic aromas. Cardamom, cinnamon, vanilla, and cloves are also sometimes added. The spices are simmered together with the tea.

Finally, the tea is chilled and poured over ice to make a refreshingly cold drink. It’s garnished with a splash of cream floating on top.

Does Thai Tea Have Caffeine?

Yes, Thai Iced Tea does contain caffeine. It is made with black tea as the base, which naturally contains caffeine. On average, a 237 ml cup of black tea contains around 47 milligrams of caffeine. Despite its caffeine content, Thai Iced Tea is a popular and refreshing beverage enjoyed in Thailand and around the world. It is important to note that Thai Iced Tea also contains sugar, contributing to an energy boost along with the caffeine. If you are looking for a caffeine-free version of Thai Iced Tea, it may be challenging to find as it is not a common request in Thailand due to the traditional preparation methods using black tea.

How Does the Caffeine in Thai Tea Compare to Other Beverages?

To put the caffeine content of Thai tea into context, let’s see how it compares to the caffeine in other popular beverages.


  • An 8 oz Thai tea with 30-50mg caffeine has around half the caffeine of a typical 8 oz coffee, which averages 100mg.
  • However, caffeine concentration varies hugely in coffee based on the roast, grind, and brew methods. Espresso has the most caffeine of any coffee style.
  • Thai tea and coffee both supply caffeine, but have very different flavor profiles. Coffee is bitter and acidic, while Thai tea is malty, tannic, sweet, and creamy.

Matcha Green Tea

  • Matcha is a powdered green tea with very high caffeine content. A 4 oz serving can have around 70mg of caffeine.
  • Matcha has more caffeine than Thai tea when comparing equal volumes. But the serving size of matcha is usually smaller.
  • Matcha also contains L-theanine, which moderates the effects of caffeine and promotes alert calmness rather than jittery energy.

Other Black Teas

  • Thai tea likely has modestly more caffeine than most black tea varieties like English Breakfast or Earl Grey.
  • This is because Thai tea is brewed very strongly for a prolonged time to extract maximal flavor and tannins.
  • However, high-caffeine Ceylon or Assam black tea brewed for several minutes can come close to Thai tea caffeine levels.

Nutritional Value and Health Impacts

Thai tea can be a healthy beverage choice with some caveats. Black tea contains antioxidants like flavonoids, which may help reduce inflammation and lower the risk of chronic diseases. Traditional Thai ingredients like ginger, turmeric, and tamarind also have antioxidant and anti-inflammatory properties.

However, the high sugar content detracts from Thai tea’s nutrition. A 12-ounce serving can contain up to 50 grams of added sugar. Too much-added sugar is linked to obesity, diabetes, and heart disease. When brewing Thai tea, cut the sugar content in half or substitute a non-nutritive sweetener. Agave, honey, and monk fruit extract offer alternatives. Sweeten to taste ‒ the spices already provide plenty of flavor.

The caffeine in Thai tea provides a lift, but those with anxiety, sleep issues, or medication interactions should limit intake. Pregnant women should restrict caffeine. Overall, when consumed in moderation without added sweeteners, Thai tea can be a flavorful, moderately caffeinated component of a balanced diet.

Enjoying Thai Tea Responsibly

As Thai tea gains devoted fans worldwide, its consumption should be thoughtful and moderate. Follow brewing directions carefully – over-steeping or boiling Thai tea can extract unpleasantly bitter flavors. Choose organic, ethically sourced tea blends to support sustainability.

Reduce added sugars by experimenting with alternative natural sweeteners at lower amounts. Be mindful of caffeine intake to avoid side effects. Sip mindfully and savor the aromatic spices and flavors. Share feedback or creative recipes with fellow Thai tea lovers.

Most importantly, appreciate the centuries of Thai culture embodied in each cup of Thai tea. At its origins, it represents Thai traditions of community, celebration, and hospitality. As we consume this drink responsibly, we can ensure Thai tea’s unique legacy endures for generations to come.

How to Make Authentic Thai Iced Tea at Home?

To get that perfect taste and color, here’s a quick guide to brewing authentic Thai iced tea at home:


  • 3-4 Thai black tea bags or 2 Tbsp loose tea
  • 1 1⁄2 cups water
  • 1⁄2 can sweetened condensed milk
  • 1⁄4 cup heavy cream
  • White sugar or simple syrup to taste
  • Star anise, cinnamon stick, and/or crushed tamarind for flavor (optional)

Brewing Method:

  1. Simmer the tea bags or loose tea in the water for 5-7 minutes with your choice of spices.
  2. Remove tea bags or strain the loose tea leaves.
  3. While the tea is brewing, prepare the milk mixture. Heat the condensed milk and heavy cream in a small saucepan over low heat until just warmed through, about 3-5 minutes.
  4. Add sugar or simple syrup to taste. Start with 1-2 Tbsp and add more if desired.
  5. To assemble, fill a glass with ice and pour the hot brewed tea over the ice.
  6. Add the warm milk mixture and stir gently to combine. The ice will cool down the tea and thicken the milk.
  7. Top with an extra drizzle of cream and garnish with cinnamon or star anise if desired.

Tips for Controlling Caffeine:

  • Use a lower-caffeine black tea like Darjeeling or Decaf Assam.
  • Reduce the brewing time to 3-4 minutes for less potent tea.
  • Use fewer tea bags or teaspoons of loose-leaf tea.
  • Substitute up to half of the black tea with herbal hibiscus or rooibos tea for a floral note.
  • Add extra milk or cream to mellow the caffeine effect in each cup.

With the right techniques and ingredients, you can brew Thai iced tea at home that’s as fresh, flavorful, and colorful as your favorite restaurant.

6 thoughts on “Does Thai Tea Have Caffeine? What You Need to Know?”

  1. Well, you could find the caffeine content if you have access to a HPLC instrument and some pure caffeine solution. But every batch is going to be a bit different depending on how much tea you use and how long you steep it. All I can say is that the amount of caffeine is probably less than there would be in the same volume of coffee.

  2. Everyone knows what Thai tea is. I’ve been to Thailand and had a thousand Thai teas. You’re just being difficult. It’s orange because of food coloring.

  3. My question comes since I read that it is “Red Tea Powder”. From my understanding, red tea does not have caffeine, am I wrong?

  4. I drink these whenever I find them at the store. These are actually pretty good. It’s not the quality your going to get from an actual restaurant though. It’s more of a ‘quick and easy’ on the go thing.
