Guayakí Yerba Mate | 16,077 followers on LinkedIn. Big News. We have a new name. Still the one you love, now Yerba Madre. | Yerba Madre—formerly Guayakí Yerba Mate—is the nearly 30-year pioneer of regenerative yerba mate [yer-bah ma-tay] and the category leader in ready-to-drink mate beverages across North America. The name Yerba Madre, meaning “Mother Herb,” is a tribute to Mother Earth and the ancestral wisdom of the Indigenous communities who have cultivated yerba mate for generations —a reflection of the values the brand has championed since day one. Headquartered in Sebastopol and Venice, California, Yerba Madre sources organic, shade-grown yerba mate in direct partnership with 255 family farmers and Indigenous communities across Argentina, Brazil, and Paraguay.
