Nearly half of the world population drinks tea every day. The most popular kinds of caffeinated teas are green, black, and oolong teas, and the popularity of each tea varies geographically. Black tea consumption far exceeds the other two types of tea. In contrast, green tea is the most common variety in Asia. Oolong tea topped the charts in southern China.

Black tea includes more caffeine than green tea. However, the caffeine content is also related to the cooking process. The steeper the tea, the higher the caffeine content. Caffeinated teas usually contain less caffeine than coffee:

  • One 8-ounce cup of coffee contains about 95 milligrams of caffeine.
  • The same amount of black tea is roughly 48 milligrams.
  • A cup of green tea contains only 29 milligrams.
  • Oolong provides about 38 milligrams of caffeine per cup
  • Decaffeinated black green oolong tea contains very little caffeine.
  • Many herbal teas are decaffeinated.

Caffeine and herbal teas contain small amounts of minerals such as potassium, phosphorus, magnesium, sodium, copper and zinc. The actual amount will vary depending on the age and growing conditions of the tea plant. For example, a cup of herbal tea like chamomile contains only about 5 milligrams of calcium. Tea is also a source of fluoride, but the amount can vary depending on the type and amount of water used to make it.
