Drinking mate is a common social practice in Paraguay, Uruguay, Argentina, Chile, and southern Brazil among people of all ages, and is often a communal ritual following customary rules. Friends and family members share from the same container, traditionally a hollow gourd (also called a , , or simply in Spanish, a or in Portuguese, or a in Italian), and drink through the same wooden or metal straw (a in Spanish or in Portuguese). The gourd is given by the brewer to each person, often in a circle, in turn; the recipient gives thanks, drinks the few mouthfuls in the container, and then returns the mate to the brewer, who refills it and passes it to the next person in clockwise order. In southern Chile the ritual is different in the sense that the recipient is not supposed to give thanks until he's done drinking the beverage. Although traditionally made from a hollowed calabash gourd, these days mate "gourds" are produced from a variety of materials including wood, glass, bull horns, ceramic, and silicone.
