How much caffeine is in your tea?

Pick a tea and your cups per day to see the caffeine per cup, the daily total, and how it stacks up against coffee — with every common tea on one chart.

Caffeine per ~8 oz cup (representative)

Rooibos / herbal: 0 mg (naturally caffeine-free)

White tea: ~15–30 mg

Green tea: ~25–45 mg

Oolong tea: ~30–50 mg

Black tea: ~40–70 mg

Pu-erh: ~30–70 mg

Matcha (1 tsp): ~60–80 mg

Espresso (1 shot): ~60–80 mg

Brewed coffee: ~80–100 mg

Representative figures per ~8 oz cup; brewing strength, leaf grade and steep time all change the real number. The ~400 mg/day figure used for context is a reference the U.S. FDA has cited for healthy adults, not a recommendation. This is general information, not medical or dietary advice.
