Uruguay Mate: The Drink, the Kit and How a Round Works

The Drink and the Leaf

Mate is an infusion of yerba mate, the dried and ground leaves of Ilex paraguariensis, a holly tree native to southern South America. It is the national drink of Uruguay, Argentina and Paraguay, and it contains caffeine, which is why a thermos gets refilled from morning to night. The city's official tourism site notes that mate was drunk by Charrúas, Guaraníes and criollos before the nation existed, and that it later became the national drink across all social classes.

That last point matters for the visitor. Mate is not a rural curiosity or a tourist ritual. Spanish Wikipedia notes it is drunk every day at home and at work, where a thermos and a gourd often sit beside the computer.

If someone offers you theirs, that is inclusion, not a sales pitch.

The Biggest Drinkers Grow None

Here is the odd part of the story. Uruguay drinks about 8 kg of yerba per person per year, the highest figure in the world, yet it has imported practically all commercially consumed yerba since 1920. The plant itself is not foreign to the country.

It grows wild in Uruguay's hill forests, but local production never scaled to match the national habit, so the yerba in almost every gourd you see is imported. Small-scale projects to grow it commercially in the east of the country are under way. For you the consequence is simple.

The yerba you buy in Montevideo was packed for Uruguayan taste, not grown there.

The Gourd

The vessel is also called a mate, and the classic one is a porongo, a gourd of Lagenaria siceraria, hollowed and cured. Uruguayan gourds are usually big, with a large opening, which suits the local habit of generous pours and constant sipping. You will also find mates in wood, ceramic and metal, and silver-decorated versions that belong on a display shelf rather than in a backpack.

One rule of the house matters if you plan to keep drinking at home: a gourd cured for bitter mate stays bitter mate. The bitter gourd is not used for sweet mate, because it keeps the flavour of the leaf. A dedicated gourd for sweet versions is the usual solution.

The Bombilla

The bombilla is a metal straw with a filter at the drinking end. It does two jobs at once. It carries the infusion to your mouth and it strains out the fine yerba dust that would otherwise come with it.

The straw sits in the gourd before the first pour and stays there through the whole round. Quality runs from plain steel to fine silver, and silver bombillas are collectors' pieces that turn up in museum cases as much as in kitchens. For a first set, any sturdy steel bombilla from the fair does the same work as an ornate one.

The Termo and the Matera

Uruguay turned mate into a walking drink by switching from the kettle to the thermos. Wikipedia describes the national scene plainly: people walk the streets with mate and thermos, the gourd in one hand and the flask under the arm. Older kits used cork-topped flasks called picos cebadores, some shaped like a horse's head, with a spout for pouring straight into the gourd.

The word you need at a shop is matera, the Uruguayan term for the bag that keeps the thermos and the mate upright and together. Materas range from simple canvas slings to tooled leather, and they answer the one practical problem of street mate, which is that a gourd tips over.

Preparation looks fussy the first time and takes a minute once your hands know it. The steps below follow the method described on Wikipedia's mate articles, with the Uruguayan temperature rule. What matters most is the water. Hot, never boiling, or you scald the leaf and the roof of your mouth.

1. Fill the gourd half to three-quarters with yerba. 2. Cover the mouth with your palm, invert and shake, then tilt the gourd so the yerba piles up on one side and a slope runs down the other. 3. Pour a little cool water into the empty space to wet the bottom of the slope and wait two or three minutes so the leaf settles without washing away. 4. Insert the bombilla into the cleared space, filter end down, and leave it there for the whole session. 5. Pour water at 70-85°C, never boiling, into the space beside the yerba pile and sip through the bombilla. 6. Keep refilling the same spot until the mate is lavado and tastes of water, then move the pile to the other side to revive it, which is called reformar el mate.

The Cebador Serves

One person runs the round. The cebador prepares the mate, usually drinks the first fill to check the temperature and the taste, then passes the gourd and refills it as it comes back. The gourd travels in turn around the circle, and in Uruguay the direction is clockwise.

Drink everything in the gourd before handing it back. Country custom adds a note of courtesy: the owner of the mate prepares it, and preparing someone else's mate without asking is considered rude. As a guest your only job is to accept, drink, pass back and keep the circle moving.

Gracias Means Stop

The word that governs the round is gracias. You do not thank the cebador for each refill. Handing back the gourd and saying gracias is the signal that you want no more, and a polite cebador will skip you from then on.

Drink it all before you pass it back, empty gourds keep the count honest. Is it rude to refuse mate? No. Decline politely with a gracias, and nobody minds.

The saying un mate no se le niega a nadie, a mate is refused to no one, describes hospitality, not an obligation. First-timers who worry about this rule worry more than their hosts do.

Bitter, Not Sweet

Uruguayans drink mate hot and bitter, called amargo, and that is the standard you will be offered. Sweet mate exists, but it belongs more to Argentina, and a gourd cured for bitter stays bitter, which is why the two rarely share a vessel. Children in Uruguay often grow up on mate de té, black tea with lemon drunk through a bombilla from a cup rather than the gourd, a gentle entry point if straight yerba strikes you as too much.

The traditional companions are bizcochos and tortas fritas, the fried rounds with a hole in the middle, which turn any mate round into a snack. Read more in our guide to Uruguayan food.

On a Tour

Several walks put a mate in your hands with someone to explain the ritual. The street food walk with five tastings and traditional mate tea runs three hours from FAUNA Montevideo and costs $62.91. Cruise passengers with half a day can take the small-group shared tour with an optional mate stop at $65, which adds a chance to try mate, possibly with churros, at the oldest bar in downtown Montevideo. For the cheapest entry, the Ciudad Vieja walking tour at $20 has a guide who covers mate among other local customs such as football.

Tristán Narvaja Sunday Fair

The Feria de Tristán Narvaja runs every Sunday from about 9:00 to about 16:00 on Tristán Narvaja street at 18 de Julio in Cordón. It opened in 1909 selling fruit and vegetables and now sells almost everything, from fresh pasta for Sunday lunch to books, antiques, records and old household goods, which makes it the likeliest place in the city to find a used gourd, a silver-trimmed bombilla or a leather matera with some years on it. Go in the morning for the widest choice and bring small notes in pesos.

Check a gourd for cracks before you pay, and ask whether it has been cured. The rest of the week's shopping is on the Montevideo shopping page.

Souvenir Lanes and Markets

Ciudad Vieja makes the shopping easy because the lanes are close together. Peatonal Pérez Castellano runs from Peatonal Sarandí down to the Mercado del Puerto, lined with souvenir shops and food places, and it ends at the Mercado de Artesanos, the crafts market, so one short walk covers several places to compare gourds and bombillas. Further inland, the Mercado Agrícola de Montevideo, opened 1913 as a wholesale market and reopened restored in 2013, holds about 100 stalls plus a food court, with craft and souvenir shops among them.

Entry is free and there are four step-free entrances with ramps, so it works in any weather. Details in our Ciudad Vieja guide.

Museo del Gaucho y la Moneda

For mate as heritage rather than shopping, the Museo del Gaucho y la Moneda moved in October 2024 to the central hall of the Banco República headquarters in Ciudad Vieja. Its collection covers silverwork and knives, paintings, sculpture and historic pieces of gaucho life, and Spanish Wikipedia says it holds the country's largest display of mates and bombillas. Hours and entry are not published on the official news page announcing the move, so check before you go.

The hall sits in the heart of Ciudad Vieja, so pair it with the lanes nearby.

Mate contains caffeine. Wikipedia notes that mateína, the substance long credited with special properties in mate, is in fact caffeine itself, so the effect you feel is the familiar one: alertness and, in a round that lasts all afternoon, a slow steady dose rather than one big hit. The health question that research does flag is temperature, not the leaf.

Wikipedia links drinking very hot beverages, above 65°C, to oesophageal cancer, and notes that smoke-dried yerba carries PAHs, compounds also found in smoked foods. The practical translation is already the Uruguayan rule. Use water at 70-85°C, never boiling, and let the first pours settle and cool a little before you sip.

There are no medical promises to be made either way, so treat mate as a pleasure and a caffeine source, and mind the heat.
