Understanding the Caffeine in Earl Grey Tea
Earl Grey tea's caffeine content comes from its base, which is traditionally black tea made from the leaves of the Camellia sinensis plant. Caffeine is naturally present in this plant. The distinctive Earl Grey flavor, derived from caffeine-free bergamot oil, does not contribute any caffeine.
How Much Caffeine Is Actually in Earl Grey?
The exact caffeine amount in Earl Grey varies depending on several factors. An 8-ounce cup typically contains between 40 and 70 milligrams. Key factors influencing this amount include:
- Brewing Time: Longer steeping extracts more caffeine.
- Water Temperature: Hotter water leads to more efficient caffeine release.
- Tea Leaf Form: Loose-leaf tea may release caffeine slower than tea bags containing smaller leaf pieces.
- Tea Variety: The type of black tea used as the base affects the initial caffeine level.

- Herbal Teas with Bergamot Flavor: Some herbal blends achieve the bergamot taste using caffeine-free ingredients.
