Iced tea is the everyday American thirst-quencher: strong black tea brewed, chilled, and poured over ice, most often unsweetened outside the South and frequently served with a wedge of lemon. Clear and brisk, it is the default non-soda drink at diners and dinner tables across much of the country, distinct from the syrupy-sweet sweet tea of the South. It is brewed by the pitcher and drunk all day, especially in summer.
Tea was drunk hot in America from colonial times, but pouring it cold over ice became practical only once commercial ice was widely available in the nineteenth century, and early cookbooks printed iced-tea recipes (often made with green tea and spiked with liquor) well before 1900. The drink's mass popularity is widely tied to the 1904 St. Louis World's Fair, where a tea promoter is often credited with serving it iced to a sweltering crowd; that fair-origin story is a popular simplification, since iced tea recipes clearly predate it, but the fair did help spread it nationally. Through the twentieth century black tea displaced green as the American standard, and the drink split into a sweetened Southern style and an unsweetened pour elsewhere.
Brisk, clean, and astringent, with the tannic grip of strong black tea and a cooling bitterness that lemon brightens. Unsweetened, it is refreshing and slightly drying on the tongue; the flavor is all tea, with no distraction. Over-brewed or stale tea turns cloudy and harshly bitter, while a good glass stays clear, brisk, and faintly aromatic. Best served very cold over plenty of ice.
Brewing extracts tannins (polyphenols), caffeine, and aroma compounds from the leaf, and the trick is controlling that extraction: hotter water and longer steeping pull more tannin and turn the tea bitter, so a clean iced tea is brewed strong but not over-steeped, then diluted by the melting ice. The common 'cloudiness' of refrigerated tea is caused by tannins and caffeine binding into tiny insoluble complexes as the tea cools; this is reduced by not over-brewing, by a pinch of baking soda to alter the acidity, or by a small splash of hot water to redissolve the haze. Cold-brewing — steeping the leaf in cold water for hours — extracts fewer tannins and yields a smoother, less bitter, naturally clear tea.
Variations
The great divide is sweetened Southern sweet tea versus the unsweetened standard elsewhere; an Arnold Palmer cuts it half-and-half with lemonade. Green-tea and herbal iced teas are common, as are peach, raspberry, and mint infusions. Cold-brew iced tea is smoother and clearer; a 'sun tea' is brewed in a jar in direct sunlight (though food-safety guidance warns of bacterial growth); and Thai iced tea and Hong Kong-style milk tea are distinct, dairy-rich traditions of their own.

Bring the water to a boil, then remove from the heat and add the black tea bags or loose leaves.
- 24 min
Steep 3 to 5 minutes for a strong but not over-extracted brew, then remove the tea promptly.
Watch outPull the tea at 3 to 5 minutes — long enough for a strong brew, but leave it longer and the tannins turn it bitter, and no dilution fixes that.
- 31 min
Stir in sugar now if making a sweetened version, while the tea is still hot.
- 430 min
Let the brewed tea cool to room temperature to limit cloudiness.
Watch outLet the brew cool to room temperature before chilling — dropping hot tea straight into cold makes the tannins cloud it; a slow cool keeps it clear.
- 52 min
Pour into a pitcher over ice, or refrigerate until cold, then serve over fresh ice.
- 61 min
Garnish each glass with a lemon wedge and a sprig of mint if desired.
