QUICK ANSWER
Pure rooibos is naturally caffeine-free. Unlike black, green, white or oolong tea, rooibos does not come from Camellia sinensis, so caffeine is not naturally present and no decaffeination process is needed.
If you're trying to cut back on caffeine, rooibos is unusual for one simple reason: unlike black or green tea, it never contained caffeine to begin with.
Rooibos comes from Aspalathus linearis, a South African plant that is completely different from Camellia sinensis — the plant used to make black, green, white and oolong tea. Because caffeine is not naturally present in rooibos, no decaffeination process is needed.
Is Rooibos Actually Tea?
Not in the strict botanical sense.
Black, green, white and oolong teas all come from Camellia sinensis. Different processing methods create very different styles and flavours, but they all begin with the same tea plant.
Rooibos comes from Aspalathus linearis instead.
It is commonly called “rooibos tea” or “red bush tea”, but technically it is an herbal infusion rather than a true tea.
| Drink | Plant | Naturally contains caffeine? |
|---|---|---|
| Black tea | Camellia sinensis | Yes |
| Green tea | Camellia sinensis | Yes |
| White tea | Camellia sinensis | Yes |
| Oolong tea | Camellia sinensis | Yes |
| Rooibos | Aspalathus linearis | No |
Rooibos vs Decaf Tea
Rooibos and decaf tea may both suit someone looking to reduce caffeine, but they are not the same thing.
Rooibos starts without caffeine.
Decaf tea starts with caffeine.
A decaffeinated black or green tea is still made from Camellia sinensis, but most of its naturally occurring caffeine is removed during processing.
So the distinction is straightforward:
Caffeine-free means caffeine was not naturally present to begin with.
Decaf means most of the original caffeine has been removed.

Can a Rooibos Blend Still Contain Caffeine?
Yes.
Pure rooibos contains no caffeine naturally, but a finished blend depends on every ingredient that goes into it.
Many rooibos blends combine it with fruits, flowers, herbs or spices that are also caffeine-free. Others may include ingredients that naturally contain caffeine, such as:
- black tea
- green tea
- yerba mate
So if avoiding caffeine matters to you, check the complete ingredient list rather than relying only on the word “rooibos” on the front of the pack.
How We Look at Caffeine-Free Blends at IMPRESSA
At IMPRESSA, we look at the full blend rather than the base ingredient alone.
A rooibos base does not automatically make the finished tea caffeine-free. The other ingredients need to be considered too.
That same principle guides how we approach our Caffeine-Free Tea Collection: we look at the complete ingredient list, not simply the base ingredient.
It is a small distinction, but it makes choosing tea clearer — especially when comparing flavoured blends.
If you are cutting back on caffeine but still want the ritual of a brewed cup, rooibos offers a naturally caffeine-free place to start.
