Thai Tea
Thai tea, known in Thailand as cha yen ('cold tea'), is a strong, sweet iced drink of black tea with condensed and evaporated milk, famous for its bright orange color. The tea is brewed very strong, heavily sweetened with sugar and sweetened condensed milk, then poured over ice and topped with a float of evaporated milk that gives the classic two-tone look. The signature orange hue does not come from the tea itself but from added food coloring in the traditional Thai tea mix.
A good Thai tea is brewed genuinely strong, so the black tea (and its slightly spiced, sometimes vanilla-tinged character in the traditional mix) holds up against heavy sweetening. Look for a balance where the condensed milk reads as creamy rather than cloying, and where the evaporated-milk top adds richness without drowning the tea. The traditional 'Thai tea mix' contains added coloring (and sometimes flavorings such as star anise or tamarind), which is authentic to the style, though some modern shops use uncolored black tea for a more natural russet-brown cup. Sweetness is rarely adjustable in the classic version, since the condensed milk is the sugar, so expect it sweet. Freshly brewed and freshly built over ice beats a pre-mixed batch that has been sitting and diluting.
Thai tea in its modern condensed-milk form is associated with Thailand's twentieth-century street and restaurant culture, where strong black tea met imported sweetened condensed and evaporated milk. The most recognizable commercial tea mix is the long-running 'Number One Brand' (ChaTraMue), whose orange-dyed blend defines the look and flavor most people picture. Served cold as cha yen or hot as cha ron, it is a staple of Thai eateries and night markets, and it travelled worldwide alongside Thai restaurant cuisine.
Steep Thai tea mix (or a strong black tea) in very hot water for several minutes to get a deep, concentrated brew, then strain, traditionally through a cloth sock filter. Stir in sugar and sweetened condensed milk while hot until fully dissolved. Pour the sweet tea over a tall glass of ice, then float evaporated milk (or a little half-and-half) on top for the two-tone effect. For the hot version, skip the ice and serve the sweetened, milked tea warm.
At a Thai restaurant or cafe, Thai tea usually runs €3.50-6 (about $4-6.50) per glass. Made at home, a bag of Thai tea mix yields many servings for a low per-glass cost, with condensed milk the other main ingredient. The convenience and the proper strong brew are most of the shop value.

Hong Kong Milk Tea
A close regional cousin: both brew black tea very strong and enrich it with evaporated or condensed milk, though Hong Kong's is un-dyed and cloth-strained rather than colored, and less aggressively sweet.
Milk Tea
Thai tea is a specific, intensely sweet member of the milk-tea family, defined by condensed milk and its signature coloring.
Ceylon
A robust Sri Lankan black tea of the kind that suits Thai tea's heavy sweetening; the classic mix is a broken black tea built for strength.
The vivid orange of classic Thai tea is created by added food coloring in the traditional tea mix, not by the tea leaves, which is why a cup made from plain black tea comes out a more ordinary brown.
