Caffeine in Chinese Tea
How much caffeine is in green tea, oolong, black tea, and pu'er? A practical guide for every category.
Guide
Caffeine Varies by Leaf, Not Just Category
Caffeine content depends on the cultivar, harvest time, leaf grade, and brewing method more than the category alone. Buds and young leaves generally contain more caffeine than mature leaves.
Guide
Green and White Tea
These are often lower in caffeine when brewed gently, but high-quality silver-tip whites can be surprisingly high because they are made almost entirely from buds.
Guide
Oolong and Black Tea
Oolong ranges widely depending on oxidation and roasting. Black tea is typically moderate to high in caffeine, especially when brewed strong with boiling water.
Guide
Pu'er and Dark Tea
Raw sheng pu\'er can be high in caffeine. Ripe shou pu\'er is often lower due to microbial fermentation, making it a popular evening choice.
Guide
Controlling Your Brew
Use less leaf, cooler water, and shorter steep times to reduce caffeine. For more caffeine, use more leaf, hotter water, and longer steeps.
