Thailand's everyday drinks are sweet, cold and cheap: cha yen (orange iced tea with milk), oliang (iced black coffee) and cha manao (iced lime tea) are sold at almost every market. Ask for "wan noi" if you want less sugar. For good coffee, look for beans from the northern hills, where Thailand grows its own Arabica.
This page covers the non-alcoholic drinks you will meet on a street corner or in a café, how to order them the way you like, and where the coffee itself comes from. Food has its own page in our guide to Thai dishes worth trying, and Chang, Leo and Singha are covered in our article on beer in Thailand.

Cha yen: the orange tea in a plastic bag
Cha yen means "cold tea", and it is the drink most visitors try first. A vendor pours strong, dark black tea over a cup or bag of crushed ice and finishes it with sweetened condensed milk, sometimes with evaporated milk on top. The color is the giveaway: most cha yen is a vivid orange that tea does not produce on its own, because the tea mixes sold to vendors usually contain added coloring. If you prefer to avoid it, ask what is in the mix or choose a café that brews plain tea.
Expect it to be very sweet. That is the point for many Thai drinkers on a 35-degree afternoon, but it can be a lot for anyone used to unsweetened tea. Street stalls often hand it over in a plastic bag with a straw and a loop to carry it by, which looks strange the first time and works well.
Two lighter versions are worth knowing. Cha dam yen is the same tea without milk, still sweetened. Cha manao adds lime juice, which gives a sweet and sour iced tea that many people find easier to drink in the heat than the milky version. Hot tea exists too (cha ron), but you will see far more iced drinks than hot ones outside air-conditioned cafés.
Oliang and the old-style coffee shops
Before espresso machines reached every mall, Thai coffee meant the drinks served in Chinese-Thai shophouse cafés and at market stalls. Oliang is the classic: iced black coffee, strong and sweet, brewed the old way (often through a cloth filter you will see hanging at the stall). Ask for "oliang" by name, or for "kafae yen" if you want iced coffee with milk, which usually means condensed milk and plenty of sugar.
These old-style shops are also where Thais eat breakfast: toast with condensed milk, rice porridge or dim sum. In Phuket the tradition is especially strong, and the shophouse streets of Phuket's old town are known for morning dim sum with local coffee. In Bangkok, shophouse cafés in Chinatown (Yaowarat) keep the same style alive.
Say "wan noi" before the vendor reaches for the condensed milk. Thai iced drinks are sweetened as they are made, so the request has to come first. "Wan noi" gets you less sugar, "mai wan" asks for none, and "mai sai nom" means no milk. The phrases for ordering Thai food page has more words for spice and allergies.
Northern hill coffee: where Thailand's Arabica grows
Thailand grows two kinds of coffee in two different places. Arabica grows in the cool highlands of the north, at around 1,000 meters and higher. Robusta grows in the south, in provinces such as Chumphon and Ranong, at much lower altitudes. So neither "all Thai coffee is Robusta" nor "all Thai coffee comes from the northern hills" is true.
The Department of Intellectual Property counts 11 registered coffee GIs (geographical indications, a protected origin name like Champagne for wine) from eight provinces, as of January 2026. They are:
| Region | Registered coffee names | Type |
|---|---|---|
| Chiang Rai | Doi Tung, Doi Chang | Arabica, highland |
| Chiang Mai | Thep Sadet | Northern highland |
| Nan | Doi Suan Ya Luang Nan | Arabica, 1,000–1,500 m |
| Tak | Doi Musoe Tak | Northern highland |
| Nakhon Ratchasima | Wang Nam Khiao, Dong Mafai | Northeast |
| Chumphon | Khao Thalu, Tham Sing Chumphon | Robusta, low altitude |
| Ranong | Ranong coffee | South |
| Krabi | Mueang Krabi coffee | South |
According to the department, GI coffee sold for more than 1,497 million baht in 2025, and Doi Suan Ya Luang Nan from Nan province was the best seller. Doi Chang, grown at 1,000 to 1,700 meters in Chiang Rai, is also registered as a protected name in the EU and Japan, and its beans averaged about 1,600 baht per kilo at retail in 2025.
Doi Tung, also in Chiang Rai, has a history visitors often ask about. The Mae Fah Luang Foundation began the Doi Tung Development Project in 1988 to give hill villages an income other than opium, and coffee and macadamia were the first crops planted along with new forest. Coffee from the project is sold under the DoiTung brand. Doi Tung and Doi Chang are separate places and separate GIs, although they are often confused.
Where to drink good coffee in the north
If coffee is part of your reason for going north, base yourself in Chiang Mai or Chiang Rai. Chiang Mai's café scene is centered on the Nimman area, which our Chiang Mai guide describes along with the rest of the city. Chiang Rai is the province of Doi Tung and Doi Chang; the Chiang Rai city page describes the town, and the bus between the two cities is explained in Chiang Mai to Chiang Rai.
The village of Mae Kampong east of Chiang Mai grows coffee too, and it appears among our favorite excursions out of Chiang Mai. When you buy beans, the useful things to read on the bag are the origin (one named hill, or a GI name from the table above), the roast date and whether it is Arabica or Robusta. A GI name on the label is a protected claim; "mountain coffee" on its own is not.
Specialty cafés in the cities serve espresso, pour-over and cold brew much as they would in Singapore, Kuala Lumpur or Shanghai, and payment by Thai QR code is common; if you rely on a card, Alipay or WeChat Pay, ask at the counter before you order. If you plan to work from a laptop for hours, a coworking space is fairer to the café and usually has better Wi-Fi.
Convenience-store coffee and other everyday drinks
The cheapest reliable cup is often the coffee counter inside a convenience store. Most 7-Eleven branches have one, and our piece on what makes 7-Eleven special explains the rest of the shop. Fridges in every store also hold canned coffee, bottled green tea (usually sweetened, so read the label) and soy milk.
Beyond tea and coffee, fresh fruit shakes and fresh coconuts are everywhere at markets; our Thai fruit guide covers what is in season. Our article on Thai tap water explains what Thais drink instead of tap water.
Sweet iced drinks are not a substitute for water. On a hot day it is easy to drink three cha yen and little else. Carry plain water as well, especially if you are walking around temples at midday. The warning signs of heat illness are listed in our hot-weather health advice.
Frequently asked questions
Why is Thai tea orange?
Black tea alone turns brown, not orange. The bright color of most street cha yen comes from the commercial tea mixes vendors use, which usually contain added coloring. Cafés that brew their own tea often serve a browner drink.
How do I order a Thai iced coffee or tea with less sugar?
Say "wan noi" (a little sweet) when you order, before the drink is made. "Mai wan" means no sugar, and "mai sai nom" means no milk. Condensed milk is already sweet, so a drink with milk will never be fully unsweetened.
Is Thai coffee Arabica or Robusta?
Both. Arabica grows in the northern highlands, for example Doi Chang and Doi Tung in Chiang Rai and Doi Suan Ya Luang in Nan. Robusta is the southern coffee, grown at low altitude in provinces such as Chumphon and Ranong.
What is oliang?
Oliang is the traditional Thai iced black coffee from shophouse cafés and market stalls. It is strong and served sweet over ice. If you want milk in it, ask for kafae yen instead, and say "wan noi" if you want it less sweet.
Where can I buy Thai coffee beans to take home?
Cafés and shops in Chiang Mai and Chiang Rai sell beans from named hill areas, and supermarkets in the big cities stock several Thai brands. Look for a GI name or a single origin on the bag, a recent roast date, and check your home country's rules for bringing food in.
