Frequently asked questions

Which teas are highest in caffeine?

Black teas, pu-erh and some green teas such as matcha are usually the strongest. Each product page lists the caffeine level per gram.

How do I brew a stronger cup?

Use a little more leaf and water just off the boil, 95–100°C (200–212°F), and steep black tea for 4–5 minutes.

Does tea have as much caffeine as coffee?

Usually less. Even a strong cup of black tea typically has less caffeine than a cup of brewed coffee.
