## What is yerba mate?

Yerba mate is both a plant product and the drink prepared from it. The accepted botanical species is Ilex paraguariensis, an evergreen shrub or tree in the holly family. Producers harvest leaves and young stems, then heat, dry, mill, and often age them before packing.
The plant is native across parts of northeastern Argentina, Brazil, Paraguay, and Uruguay. Preparation traditions differ across the region, but the shared pattern is repeated infusion through a filtered straw called a bombilla.

## How to prepare hot yerba mate

### Fill and tilt

Add yerba to the vessel, cover the opening, and tilt it so the dry leaf forms a slope with a lower wet side.

### Protect the dry side

Moisten the lower side first. This helps the leaf bed hold its shape and keeps part of the yerba dry for later pours.

### Place the bombilla

Insert the filtered end into the moistened pocket and leave it in place instead of stirring the whole vessel.

### Pour in one area

Add hot, not boiling, water beside the bombilla. Refill the same pocket and gradually wet more leaf as the flavor fades.


## Regional style signals

- Argentine styles: Often balance leaf, stems, and some powder, with aged profiles that can range from gentle and cereal-like to woody and smoky. (/yerba-mate/origins/argentina)
- Paraguayan styles: Frequently lean bold, herbal, or refreshing and are strongly associated with both hot mate and cold terere preparation. (/yerba-mate/origins/paraguay)
- Brazilian and chimarrao styles: Often look greener and fresher, with very fine cuts that call for a suitable cuia, bomba, and careful water placement. (/yerba-mate/origins/brazil)
- Uruguayan-style cuts: Commonly use a fine, powder-rich cut and a strong profile. Style and production origin should be checked separately on each product. (/yerba-mate/guides/uruguay)
