Caffeine In Tea

Welcome to our hub page on the caffeine content of tea. Tea is a popular beverage enjoyed around the world for its flavor, aroma, and potential health benefits. There are a plethora of teas available to choose from. These include green tea, black tea, oolong tea, rooibos, peppermint, chamomile and many, many more. And, of course, each type of tea has its own unique characteristics, flavor profile and caffeine content.

Tea drinkers often ask how much caffeine is in their favorite beverage. While most types of tea do contain some caffeine, the amount can vary drastically across different varieties.

As a general rule of thumb, black tea tends to have the most caffeine, followed by oolong, green, and white teas, which have progressively lower caffeine content. Herbal teas such as rose, mint and lavender are not made from the leaves of the tea plant, and thus, do not contain caffeine.

On this page, you will find a brief overview of the caffeine content of different types of tea. If you want to learn more about a specific type of tea, you can follow the links to our more detailed tea-specific pages.
