Best Thai Tea Mixes – Authentic Orange Cha Yen Blends Reviewed

By • Updated August 2026

What Makes Thai Tea Different?

Unlike Indian chai, which leans on cardamom, ginger, and black pepper, Thai tea relies on star anise, sometimes tamarind, and a black-tea base that's closer to Ceylon or Assam. The signature orange colour comes from food-grade dye or natural annatto, and the brew is always sweetened before serving—usually with condensed milk and sugar syrup. The result is bold, aromatic, and unmistakably South-East Asian.

That lurid orange glow, the sweet vanilla-spice kick, the contrast of ice against creamy condensed milk—proper Thai iced tea (cha yen) is one of the world's most photogenic and crave-worthy brews. Yet making it at home in the UK has long meant hunting down the right tea mix, because Thai tea is not chai, and it's not your standard milk tea either. It's a distinct beast: typically a robust Ceylon-style black tea spiked with star anise, tamarind seed, and often food colouring, designed to be brewed strong, sweetened heavily, and served over crushed ice with a float of evaporated or condensed milk.

In 2026 the Amazon.co.uk selection has matured, and you can now get hold of imports that Thai restaurants swear by—as well as a few shortcuts. We reviewed four readily available Thai tea mixes to see which deliver that authentic tangerine hue and aromatic depth, and which fall flat. Whether you're after the heritage recipe from 1945 or the convenience of single-serve sachets, this round-up will steer you to the real deal.

A quick note on colour: the electric orange you see in café windows often owes as much to food dye as it does to tea leaf. That's part of the tradition, not a flaw—but it does mean what gives tea its orange tones can be either natural tannins or a squeeze bottle of E110. We haven't penalised mixes for using colourant, because authenticity here includes the gaudy visual theatre. What we have judged is flavour balance, brewing ease, and how closely each mix mirrors what you'd be served in Bangkok or Chiang Mai.

Best Overall
Number One Brand Original Thai Iced Tea Mix 400g bag with red and gold packaging

1. Number One The Original Thai Iced Tea Mix - Number One Brand Imported From Thailand - Great for Restaurants That Want to Serve Authentic and Thai Iced Teas, 400g Bag

★★★★★ (The Heritage Champion)

Number One Brand's 400 g bag is the gold standard—the same mix Thai restaurants have trusted since 1945. It delivers a deep, malty black-tea backbone laced with star anise and a faint vanilla sweetness, and the colour blooms into that unmistakable cha yen orange when you add condensed milk. Brewing instructions are printed on the back (boil, steep, strain), and the larger format means you can batch-brew for a crowd. If you want authentic Thai iced tea at home, this is the one to beat.

Pros:
  • Established 1945 formula—proven restaurant favourite
  • Rich, aromatic spice blend with genuine depth
  • 400 g bag offers excellent value per cup
  • Clear brewing instructions included
Cons:
  • Loose mix requires straining (not beginner-friendly)
  • Larger pack size may daunt occasional sippers

Best for Beginners
Number One Brand Thai Tea Mix 200g tin with tea bags inside

2. Original Number One Brand Thai Tea Mix - 200g

★★★★☆ (The Tidy Tin)

Same heritage brand, smaller tin, tidier format. This 200 g version comes in tea-bag form, which means no messy straining and a gentler learning curve for first-timers. The flavour profile is nearly identical to its big sibling—spiced, robust, and genuinely Thai—but the convenience of bags does mean a slightly less intense extraction. Still, if you value ease and portion control over maximum punch, this is a smart pick. Serve hot or cold, and you'll still get that classic orange-hued brew—just with half the faff.

Pros:
  • Tea-bag format eliminates straining
  • Compact 200 g tin stays fresh longer
  • Same trusted Number One recipe
  • Perfect for occasional or beginner brewers
Cons:
  • Slightly less intense than loose-leaf version
  • Higher cost per gram than the 400 g bag

Best for Portability
Thai Tea Mix No.1 tin containing 50 sachets of original Thai tea

3. Thai Tea Mix No.1 Thai Tea Original (50 Sachets)

★★★★☆ (The Grab-and-Go)

Fifty 3 g sachets make this the most portable option in the line-up. Each single-serve pouch is pre-measured, so you can toss a few in your desk drawer or take them camping. The flavour is colourful, aromatic, and blends beautifully with cream, though it leans a touch sweeter and less complex than the Number One loose mix—think mid-tier café rather than specialist vendor. The tin keeps sachets sealed and fresh, and the format is ideal if you're introducing friends to Thai tea without committing to a bulk bag. Just don't expect the same cha qi punch as a traditional boil-and-strain brew.

Pros:
  • 50 individually wrapped sachets for ultimate convenience
  • Sealed tin preserves aroma
  • Consistent, sweet, and aromatic
  • Great for gifting or office use
Cons:
  • Less complex than restaurant-grade mixes
  • Single-use sachets generate more packaging waste

Best 3-in-1
Ranong Tea 3 in 1 Thai Mix box with 7 sachets, 210g total

4. Ranong Tea 3 in 1 Thai Mix 7 Sachets 210 g

★★★☆☆ (The All-in-One Shortcut)

Ranong Tea's 3-in-1 sachets bundle black-tea powder, creamer, and sugar into one tear-and-stir pouch—no condensed milk, no measuring, no fuss. It's wildly convenient and delivers a mild, sweet cup that's popular across Europe and Asia. The downside? You lose the ritual and the ability to tweak sweetness or creaminess to taste. The flavour is pleasant but one-note, lacking the star-anise complexity and layered maturity of a traditional mix. Serve it hot or iced when you need a quick Thai-tea hit, but don't expect to fool any spice-blend purists.

Pros:
  • True 3-in-1: tea, creamer, and sugar pre-mixed
  • No additional ingredients needed
  • Mild, accessible flavour
  • Hot or cold versatility
Cons:
  • No control over sweetness or milk ratio
  • Less aromatic depth than traditional mixes
  • Only 7 sachets per pack—runs out fast
