About Black Tea
Black tea is fully oxidized: after picking, the leaves are withered, rolled, and left to oxidize until they turn a dark copper-brown, then dried. Oxidation develops the malty, rich flavors and deep color most people picture when they think of a cup of tea. Major producers include India (Assam, Darjeeling, Nilgiri), Sri Lanka (Ceylon), China (Keemun, Dian Hong), and Kenya. Black tea is also the base of most blends, such as English Breakfast and Earl Grey.
What it tastes like
Flavors range from malty and brisk (Assam) to bright and citrusy (Ceylon) to cocoa-like or smoky (Chinese black teas). Black tea has more body than green or white tea and stands up well to milk and sugar.
Other ways to brew Black Tea
In a mug, with an infuser or a bag
Use one teaspoon (2–3 g) of loose black tea or one bag per 8 oz (240 ml) cup and pour water straight off the boil. Steep 3 minutes if you drink it plain, 4–5 minutes if you take milk. Then lift the infuser or bag out. Don't squeeze the bag; it presses out the most bitter, tannic liquid.
In a teapot
Warm the pot first with a splash of hot water. Add one teaspoon per cup, fill with boiling water, cover, and steep 4 minutes. If you want the pot to last, pour the tea off the leaves into a second pot or a thermos once the time is up, or use a pot with a removable infuser basket.
Iced black tea
Brew double strength, two teaspoons or two bags per 8 oz (240 ml) of boiling water for 4–5 minutes, then pour over a full glass of ice. Hot tea poured over ice can turn cloudy; it's harmless, and cooling the tea for a few minutes first helps. For a pitcher, brew a strong concentrate and dilute it with cold water.
Cold brew
Use about two teaspoons (5 g) per 8 oz (240 ml) of cold water and refrigerate for 8–12 hours, then strain. Cold-brewed black tea is smooth and naturally sweeter, with very little bitterness, and it stays clear. It keeps two to three days in the fridge.
Can you re-steep Black Tea?
Whole-leaf black tea will usually give a second good cup. Steep it a minute or so longer than the first, around 5 minutes, with fresh boiling water. Broken-leaf tea and tea bags give up almost everything the first time, so a second steep tastes thin. Chinese black teas such as Dian Hong are the exception: brewed with more leaf and short steeps in a small pot, they'll go four or five rounds.
Ways to drink Black Tea
With milk and sugar
Strong, malty teas like Assam and breakfast blends take milk best. Steep for the full 4–5 minutes so the tea isn't lost under the milk, and add milk after brewing so you can judge the color.
With lemon
Brighter teas like Ceylon and Darjeeling are better with lemon than with milk. Never add both, because the lemon curdles the milk.
Masala chai
Simmer one to two teaspoons of strong black tea per cup with crushed cardamom, a cinnamon stick, sliced ginger, and a few cloves or peppercorns for 3–5 minutes. Add milk and sugar, bring it back to a simmer, and strain. Because the tea simmers, chai is the one place black tea is cooked rather than steeped.
Sweet tea
For a Southern-style pitcher, steep about six bags in 4 cups (1 l) of boiling water for 5 minutes, remove them, stir in sugar while it's hot, then top up with 4 cups of cold water and chill.
