The scoop: Black tea is the most common variety and accounts for about 75 percent of global tea consumption. Like many of the teas here,
it’s made from the leaves of the Camellia sinensis plant, which are typically rolled and fermented, then dried and crushed. Black tea has a slightly bitter flavor and contains
the most caffeine—about 40 milligrams per cup. (A cup of coffee has 50 to 100.)
Health benefits: Black tea has high concentrations of the antioxidant compounds known as theaflavins and thearubigins, which have been linked
to lower levels of cholesterol, says Rebecca Baer, a registered dietitian in New York City. Research has shown that people
who drink three or more cups of black tea daily may cut their risk of stroke by 21 percent.
