Mate or maté ( MAH-tay, Spanish: [ˈmate], Portuguese: [ˈmatʃi]) is a traditional South American caffeine-rich infused herbal drink. It is also known as chimarrão or cimarrón, and ka’ay in Guarani. It is made by soaking dried yerba mate (Ilex paraguariensis) leaves in hot water and is traditionally served with a metal straw (bombilla) in a container typically made from a calabash gourd (also called the mate), but also made from a cattle horn (guampa) in some areas. A very similar preparation, known as mate cocido, removes some of the plant material and sometimes comes in tea bags. Today, mate is sold commercially in tea bags and as bottled iced tea.
Mate has been originally consumed by the Guaraní and Tupi peoples, native from South America. After European colonization, it was spread to different people and became later the national beverage of Argentina, Paraguay and Uruguay and is also consumed in the Bolivian Chaco, Brazil and Northern and Southern Chile. It was later introduced to Lebanon and Syria, where it was brought from Paraguay and Argentina by immigrants.
