Yerba mate vs black tea
The comparison a reader makes when they want caffeine from something that is not tea or coffee — and the one case in this catalogue where a botanical genuinely contains it, because yerba mate is a caffeinated holly rather than a herbal infusion.
What is being compared
These are not the same kind of thing, which is usually why they get confused. Each one is labelled with what it actually is.

Why these get confused
Yerba mate is shelved with herbal infusions, which are defined by containing no caffeine. It is the standing exception, and a reader who has learned 'herbal means caffeine-free' will get it wrong here.
Point by point
| Aspect | Yerba mate | Black tea |
|---|---|---|
| The plant | Ilex paraguariensis, a South American holly. One of three caffeinated hollies of the Americas, alongside guayusa and yaupon. | Camellia sinensis, an evergreen of the tea family. |
| Caffeine | Present. This is what separates yerba mate from every other botanical on the herbal shelf, and it is a fact about the leaf. | Present, in a range that depends far more on how the cup is made than on the category it comes from. |
| How it is drunk in its own tradition | From a gourd through a metal straw, refilled many times from the same leaf, and passed round a group by a designated server in a fixed order. The vessel and the sharing are the practice. | By the individual cup, in almost every tradition that drinks it, whether from a pot, a glass or a bag. |
| Water temperature | Warm rather than boiling, in the traditional preparation. | Near-boiling for black tea, which is the category most tolerant of a hot pour. |
| Taste | Green, grassy and markedly bitter, closer to an unsweetened green vegetable than to tea. Sweetening is common outside Argentina and Uruguay. | Malty, brisk, astringent, and enormously variable by origin and grade. |
| Where the tradition is | The Southern Cone and the Guaraní homelands — and, unexpectedly, Syria and Lebanon, carried home by returning emigrants and now an ordinary household drink there. | China first, and now most of the world. |
The short answer
Both contain caffeine, which is a compositional fact and the only one of these rows that is about content rather than practice. The choice between them is a choice between a shared, refilled, bitter drink and an individual cup, and the Western product sold on mate's tradition keeps neither the gourd nor the sharing.
