How Much Caffeine in Tea?Posted Date:3-Mar-2023
So-called “real” Tea (in other words, NOT Herbal or Fruit Tisanes) comes from the Camellia sinensis plant. This is but one of around 60 plants to naturally contain caffeine, with others including Coffee (Coffea), Cocoa (Theobroma cacao) and Yerba Mate (Ilex paraguariensis).
However, depending on the specific brew you choose, there will be varying caffeine levels in tea. This is because of its processing, which alters the chemical makeup of the leaves.
White Tea, the least processed variety, has about 15-mg per 8-oz cup. Next, there is Green Tea with 30-mg. Oolong Tea, on the other hand, contains approximately 35-37-mg, while Black Tea boasts 40-mg.
