Yerba Mate Tea Set refers to the two-piece kitchen utensil which was discovered by the Guarani indians of South America to drink a Yerba Mate tea. Popularized in Argentina and Paraguay, Yerba Mate tea is made from Yerba Maté (lex paraguariensis) leaves steeped in hot water. To prepare, the ground leaves are soaked in cold water, then hot water is repeatedly added until the Yerba Maté’s components are extracted. Between each addition of hot water, the tea is sipped through a wooden or metal straw, called a Bombilla, that filters out the leafy material.
