Caffeine in Chinese Tea

How much caffeine is in green tea, oolong, black tea, and pu'er? A practical guide for every category.

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.

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.

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.

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.

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.
