MATE

also called Yerba Mat, Paraguay Tea, or Brazilian Tea, tealike beverage, popular in many South American countries, brewed from the dried leaves of an evergreen shrub or tree (Ilex paraguariensis) related to holly. It is a stimulating drink, greenish in colour, containing caffeine and tannin, and is less astringent than tea. Although mat is an ancient Indian beverage, the plant, growing wild in Paraguay and southern Brazil, was first cultivated by Jesuit missionaries. In the wild state the plant becomes a round-headed tree; under cultivation, which improves the quality of the brew, it remains a small, multi-stemmed shrub, requiring a minimum of two years between harvests for regrowth. Drying methods vary. In Brazil the leafy branches are placed on a six-foot square of beaten earth, called a tatacua, and a fire is kindled around the area, providing preliminary roasting; the branches are next heated on an arch of poles over a fire; and the dried leaves, placed in pits in the earth, are ground into coarse powder, producing a mat called caa gazu, or yerva do polos. In Paraguay and parts of Argentina the leaves, with midribs removed before roasting, are made into a mat called caa-mri. Caa-cuys, a Paraguayan mat of superior quality, is made from leaf buds. In a newer method, similar to the Chinese procedure for drying tea leaves, the leaves are heated in large cast-iron pans. In brewing mat, the dried leaves (yerba), placed in dried hollow gourds, are covered with boiling water and steeped. The gourds, called mats or culhas, are decorated, sometimes silver mounted; the vessel may even be made entirely of silver. The tea is sucked from the gourd with a bombilla, a tube about 6 inches (15 cm) long, often made of silver, with a strainer at one end to keep leaf particles from the mouth. Mat, usually served plain, is sometimes flavoured with milk, sugar, or lemon juice. When tightly covered, it retains flavour during storage.
