Mate (mah-tay) also known as chimarrão (Portuguese) or cimarrón, is a traditional South American infused drink. It is prepared from steeping dried leaves of yerba mate (llex paraguariensis) in hot water.

It is the national drink in Argentina, though Paraguay and Uruguay also happen to claim nationality over the beverage, Drinking it is a common social practice in parts of Brazil, Chile, eastern Bolivia, Lebanon and Syria. In Brazil, it is considered to be a tradition typical of the "Gauchos", residents of the pampas (chacos, Patagonian grasslands).
