Mate is a warm or cold infusion prepared from the dried leaves of the yerba mate plant (Ilex paraguariensis). It is widely consumed across South America, especially in Argentina, Paraguay, Uruguay, Chile, Bolivia and parts of Brazil. The prepared drink has stimulating properties due to xanthine alkaloids often referred to colloquially as mateine, closely related to caffeine and theobromine. Mate is consumed both as an everyday beverage and as part of social rituals.
The basic preparation is an infusion (yerba leaves steeped in hot or cold water) served in a hollowed gourd or container. Traditional serving vessels include the calabash gourd known as a mate or guampa, and in Brazil the cup is called a cuia. The brewed liquid is sipped through a metal straw called a bombilla, which functions as both straw and filter. Bombillas can be simple tubes or incorporate a widened end with perforations acting as a sieve (filter), and are made from various metals including silver or stainless steel.
Preparation, utensils and common variants
- Yerba: Leaves are dried, sometimes smoked, then chopped and ground into a coarse powder (yerba).
- Water temperature: Hot mate uses near-boiling water; cold mate (tereré) uses chilled water or herbal infusions.
- Bombilla design: Some bombillas have slotted ends, spring sleeves, or built-in filters for sediment control (sieving).
- Naming and language: Terms vary by language and region; the word bombilla in Spanish literally can mean a small light ("light bulb") but locally denotes the drinking straw, reflecting varied Spanish usages.
Regional styles differ: in southern Brazil a finely milled, moist style called chimarrão is common; in Paraguay and parts of northern Argentina the cold infusion called tereré is popular. A tea-bag style, sometimes called mate cocido, is sold prepackaged for convenient brewing in cups. Modern production includes bottled ready-to-drink mate beverages and energy drinks that use mate extract.
Historically, indigenous Guaraní peoples used yerba mate long before European contact; its cultivation and wider adoption expanded during colonial and missionary periods. Commercial cultivation and trade spread throughout the region and later to immigrant communities. Today mate consumption has also spread internationally through migration and trade: for example, it became popular in parts of the Middle East after South American emigration, where communities in the Levant, including Middle Eastern populations and countries such as Syria and Lebanon, maintain the custom.
From a chemical and health perspective, mate contains stimulants similar to caffeine together with polyphenols and antioxidants. These compounds contribute to increased alertness, mild diuretic effects and appetite modulation; as with other caffeinated drinks, moderation is advised and certain medical conditions may warrant caution. Socially, mate is notable for its ritualized sharing: one person (the cebador) fills the gourd and passes it in a circle, a practice that emphasizes community, hospitality and conversation.
