![]() white tea has between 6 and 60 milligrams of caffeine. green tea has between 24 and 45 milligrams of caffeine. black tea has between 14 and 70 milligrams of caffeine. How much caffeine is in tea versus coffee?Ĭoffee has between 95 and 200 milligrams of caffeine. Most specialty coffee drinks, such as lattes and cappuccinos, are made with a double shot of espresso, containing 116 mg of caffeine. For example, a “single” espresso from Starbucks has about 58 mg of caffeine per 1-ounce (30-ml) shot.

That said, since dark roast coffees are less dense than light roast ones, you may use greater amounts of beans or grounds when brewing this type, yielding more caffeine per cup. However, since caffeine isn’t affected much by roasting, this may not be the case. It’s a common belief that coffee made from dark-roasted beans has more caffeine than coffee from light-roasted beans. How much caffeine is in an average coffee cup?Īn average 8-ounce (237-ml) cup of coffee contains 95 mg of caffeine. This amount rises to 59 mg after 3 minutes. For example, a mug of Earl Grey contains 40 mg of caffeine after 1 minute of steeping in 6 ounces (177 ml) of water heated to 194–203☏ (90–95☌). Teas that steep for longer and in hotter water tend to produce a more potent cup. The preparation method greatly impacts the caffeine content of tea. How does tea preparation affect its caffeine content? Second, black tea is oxidized, which increases how much caffeine is extracted during steeping. When the tea is picked impacts its caffeine levels. First, black, green and white teas all come from the same plant but are picked at different times. The variance in caffeine levels in tea comes from the harvesting and processing of tea. Robusta varietals have about twice as much caffeine as Arabica varietals. The variance in coffee comes mainly from the two species of plants. In comparison, caffeinated sodas tend to have between 20 and 50 milligrams of caffeine. white tea has between 6 and 60 milligrams of caffeine. ![]() green tea has between 24 and 45 milligrams of caffeine.black tea has between 14 and 70 milligrams of caffeine.coffee has between 95 and 200 milligrams of caffeine.Caffeine levels vary a lot, though, in both beverages. Typically, you also use more coffee beans than you’d use tea leaves for a drink.Īs a rule of thumb, coffee has about twice as much caffeine as tea. However, the coffee brewing process uses hotter water, which extracts more of the caffeine from the beans. Tea leaves contain 3.5% caffeine, while coffee beans have 1.1–2.2%. The amount of caffeine in tea or coffee can vary significantly depending on the origin, type, and preparation of the drink. ![]()
