Yes, you absolutely can get caffeinated tea.
Tea enthusiasts often categorize beverages based on their source plant. According to the provided reference, all true tea comes from a single plant, Camellia sinensis. This is the key differentiator.
True Teas Contain Caffeine
The reference clearly states that the main varieties derived from the Camellia sinensis plant all contain caffeine. These popular types include:
- Green tea: Known for its grassy or vegetal notes.
- Oolong tea: Ranging from lightly oxidized to darker, offering a wide flavor spectrum.
- Black tea: Fully oxidized, providing robust and often malty flavors.
- White tea: The least processed, typically offering delicate and subtle tastes.
These true teas inherently contain caffeine as a natural component of the Camellia sinensis leaf.
Herbal Teas Are Generally Caffeine-Free
In contrast, the reference notes that herbal teas can come from any other plant that is not Camellia sinensis. Examples include chamomile, peppermint, rooibos, and hibiscus. Most of these do not contain caffeine. While there are exceptions (like Yerba Mate), the vast majority of beverages marketed as "herbal tea" or "tisane" are caffeine-free.
Quick Summary of Tea Types and Caffeine
| Tea Type | Source Plant | Contains Caffeine? |
|---|---|---|
| Green Tea | Camellia sinensis | Yes |
| Oolong Tea | Camellia sinensis | Yes |
| Black Tea | Camellia sinensis | Yes |
| White Tea | Camellia sinensis | Yes |
| Herbal Tea | Various (not C.s.) | Generally No |
Therefore, if you are looking for a caffeinated beverage from the tea family, focus on the "true teas" derived from the Camellia sinensis plant.
