PARANÁ · BRAZIL / MATEROS UNIDOS
THE ORIGIN · THE CRAFT
A sense of place, in every gourd.
We believe great yerba maté should express where it comes from. Ours begins in Paraná, Brazil: cultivated without pesticides, dried without smoke and patiently aged for nearly seven years.
ON THE NOSE
Lemongrass, pennyroyal, earth and gentle wood.
ON THE PALATE
Explore the tasting notes
Expressive body, integrated bitterness and a lingering finish.
From Paraná 🇧🇷 to your gourd
We don't just source yerba. We show you where it comes from.
No vague claims, just specifics. Our yerba is grown without synthetic pesticides or GMOs, then air-dried instead of smoked, so nothing masks the leaf's natural flavor. The farm, the harvest, the drying method: all documented, nothing hidden.
Where it begins
Our partner farm in Paraná, Brazil: producers we work with directly, not a supplier lost in a catalog.
The leaf itself
This is Ilex paraguariensis, the plant behind everything we sell. Shade-grown, no pesticides, no GMOs: exactly as it grows in Paraná.

Why this exists
A shared tradition. A common standard.
Materos Unidos started with one conviction: a shared mate can bridge any gap. We took that idea from Montréal to Buenos Aires, entered our yerba in the first Mundial de la Yerba Mate, and came home with Gran Oro.
The award changed nothing about how we work. We still inspect every lot, still answer every message, still pour every morning. It just proved what the circle already knew.
