Does Tea Have More Caffeine Than Coffee?


It is estimated that roughly 80% of the population all over the world consumes a caffeinated product daily. The stimulating effects of caffeine have been connected to health benefits such as elevated mood, increased alertness, and increased metabolism. Caffeine is one of the most popular stimulants, and can be found in a variety of foods and beverages, although caffeine content varies depending on the particular type of beverage.

Beverage Type and Preparation Affect Caffeine Content

The amount of caffeine in a cup of coffee or tea can vary depending on the type and preparation of the beverage. Tea leaves contain approximately 3-4% caffeine, whereas coffee beans contain only approximately 1-2% caffeine. However, that does not mean tea contains more caffeine than coffee. The coffee brewing process uses hotter water than tea preparation, which pulls more of the caffeine from the coffee beans. Therefore, a single cup of brewed coffee contains more caffeine than a steeped cup of tea.

Tea Varieties

Black, green, and white teas are all prepared from the leaves of the Camellia sinensis plant. The difference between the teas is the time of harvest and the amount of oxidization the leaves go through. Black tea leaves are fully oxidized, green tea leaves are oxidized very little, and white tea leaves are not oxidized at all. The oxidization provides black tea with bold characteristics and a sharp flavour, and increases the amount of caffeine pulled from the tea leaves into the hot water. An average cup of black tea contains roughly 47mg of caffeine, but can contain up to 90mg. Green tea contains less caffeine at roughly 20-45mg per cup. White tea may contain anywhere from 6-60mg per cup. Many people believe tea has more caffeine than coffee, but the average cup of coffee contains approximately 95mg of caffeine. That is twice as much caffeine compared to the average cup of black tea. This makes tea a great afternoon drink when you need a small energy boost to get through the rest of the day.

Tea Preparation

The method the tea is prepared has a significant impact on the amount of caffeine in the tea. The more loose tea leaves added to a cup, the more caffeine will be released. Teas that are steeped for a longer amount of time will draw out more caffeine than teas that are steeped for the minimal amount of time. The temperature of the water also plays a factor in how much caffeine will be in the cup of tea. The higher the temperature of the water, the higher the caffeine content will be.


Although both coffee and tea contain caffeine, and the amount of caffeine can vary for both beverages, coffee contains more caffeine than tea. Tea is the perfect beverage when you need the energy boost, but do not want to take a large amount of caffeine. The different types of tea all have different caffeine levels, which is ideal when you want to choose how much caffeine you consume. Whether you want lots of caffeine, just a little caffeine, or maybe none at all, there is a tea that will suit your needs.
