Yerba Mate Guide: What It Is, How to Drink It & Best Brands

Yerba mate is the caffeinated herbal drink of Argentina, Uruguay, Paraguay and southern Brazil. It is sipped from a gourd through a metal straw, passed around a circle of friends, and consumed by the kilo: Argentines alone drink more than 260 million kilos of it a year.

It is also, increasingly, in American refrigerators. Canned mate now sits next to cold brew in every convenience store, and a bag of loose yerba is an easy find at any Latin grocery.

This guide covers the whole picture: what yerba mate actually is, how much caffeine is in it, the different types by country, the gear you need, how to prepare and share it properly, what science says about its benefits, and which brands to buy first.

What Is Yerba Mate?

Yerba mate (pronounced YER-bah MAH-teh) is made from Ilex paraguariensis, an evergreen holly native to the subtropical forests where Argentina, Paraguay and Brazil meet. Left alone it grows into a 50-foot tree; on plantations it is pruned into a shrub so the leaves can be picked by hand.

The word breaks into two parts. Yerba is the dried, chopped leaf. Mate comes from the Quechua mati, the gourd it is drunk from. In the Southern Cone, “mate” also means the drink, the gourd, and the whole ritual of sharing it.

It is one of the 15 staples in our guide to Argentine ingredients, and the country’s undisputed national drink.

From Leaf to Bag: How Yerba Mate Is Made

What separates one yerba from another is mostly processing, not the plant. Every bag goes through the same five stages:

1. Harvest. Branches are cut by hand between April and September, once the leaves have matured.
2. Sapecado. Within hours, the leaves pass over open flame for a few seconds. This flash-heating stops oxidation and keeps the leaf green rather than brown.
3. Drying. The leaves are dried with hot air, or in the traditional barbacuá method, over wood smoke for up to 24 hours. Smoke-dried yerba has the deeper, tobacco-like flavor of classic Argentine brands.
4. Canchado. The brittle leaves are coarsely crushed.
5. Aging (estacionamiento). The yerba rests in bags for 6 to 24 months. Aging mellows the bitterness and rounds out the flavor. Brazilian chimarrão skips this step, which is why it stays bright green and tastes fresher and sharper.

After aging, the yerba is milled to its final cut and blended. That cut, and whether stems are left in, is where the styles below come from.

A Very Short History

The Guaraní people were drinking mate long before Europeans arrived, chewing the leaves and steeping them in gourds. Spanish colonists picked up the habit in the 1500s, and the Jesuit missions of Paraguay turned it into the region’s first cash crop, so much so that it was nicknamed “Jesuit tea.”

Syrian and Lebanese immigrants who came to Argentina in the late 1800s carried the habit home, which is why Syria is one of the world’s top importers of Argentine yerba today. For the full story, read our history of yerba mate.

What Does Yerba Mate Taste Like?

Nobody falls in love with mate on the first sip. It is bitter and grassy, somewhere between strong green tea and a cup of very earthy vegetable broth, with a smoky or tobacco note in smoke-dried Argentine styles.

The first few refills of a gourd are the strongest and most bitter. As the water washes through, the flavor softens and turns sweeter and rounder. Many drinkers say the third and fourth refills are the best ones.

Things that change the taste:

• Stems. Yerba with stems (con palo) is milder. Stem-free yerba (sin palo or despalada) is stronger and more bitter.
• Water temperature. Boiling water scorches the leaf and makes it harsh. Cooler water gives a smoother cup.
• Drying method. Smoke-dried yerba tastes deeper and woodier; air-dried tastes cleaner and greener.
• Add-ins. Sugar, honey, orange peel, mint or the herb blends sold as yerba compuesta all take the edge off.

Yerba Mate Caffeine: How It Compares to Coffee and Tea

Yerba mate has about as much caffeine as coffee per cup. What is different is how you drink it. A gourd is refilled 10, 15 or 20 times, and a full session with a thermos can easily deliver more caffeine than a couple of coffees, spread over an hour or two.

Mate drinkers often describe the lift as smoother and less jittery than coffee. The usual explanation is the theobromine, a gentler stimulant also found in dark chocolate, plus the fact that the caffeine arrives in small sips over a long time rather than in one 12-ounce hit.

Types of Yerba Mate by Country

Ask for “yerba mate” in Buenos Aires, Montevideo, Asunción and Porto Alegre and you will get four different bags. Here is how they differ.

The Gear: Gourd, Bombilla and Thermos

You can brew yerba mate in a French press or a tea bag, and we get to that below. But the traditional setup is three things, and it is worth owning them.

The Mate (Gourd)

• Calabash. The original: a dried squash shell, often with a leather or metal rim. Best flavor over time, but it must be cured, dried after every use, and can crack or mold if neglected.
• Wood (palo santo or algarrobo). Adds a resinous aroma. Also needs curing and care.
• Ceramic or glass. Neutral taste, no curing, easy to clean. A good first gourd.
• Stainless steel. Indestructible and dishwasher-safe. Zero flavor contribution, which some people prefer.
• Silicone. Cheap and travel-friendly; the least traditional option.

Two of our most-read articles cover this in depth: how to select a yerba mate gourd and whether you need to cure it.

The Bombilla (Straw)

A bombilla is a metal straw with a filter at the bottom. The classic Argentine model has a flat spoon-shaped tip with small holes; Uruguayan and Brazilian versions use a wider bulb or spring filter to handle finer yerba. Stainless steel is the norm; alpaca (nickel silver) and silver are the traditional upgrades. Buy a spare. They clog, and they get lost.

The Thermos

Mate is a long drink, and nobody wants to walk back to the kettle 15 times. A good thermos with a pouring spout (Stanley is the cult favorite in Argentina; Lumilagro is the local classic) keeps water at the right temperature for hours. In Uruguay, walking down the street with a thermos wedged under one arm and a gourd in hand is simply what people look like.

Preparing Mate in a Gourd: The Short Version

This is the Argentine method, and it works for any hot mate. The whole point is to wet only part of the yerba at a time so the flavor lasts through many refills.

1. Heat the water to 150–170°F (65–77°C). Boil a kettle and let it sit 3 to 4 minutes, or pull it when the first small bubbles form. Boiling water burns the leaf and kills the flavor after two refills.
2. Fill the gourd two-thirds to three-quarters full with yerba. More than you think. This is not a teaspoon-per-cup drink.
3. Cover the top with your palm, flip it upside down and shake. This lifts the fine dust to the top (now the bottom) so it does not clog the bombilla.
4. Tilt the gourd so the yerba forms a slope. One side high and dry, the other side low. Argentines call the high side the montañita, the little mountain.
5. Pour a splash of cool or warm water into the low side. Wait a minute for it to soak in. This “wakes up” the yerba gently and protects it from the heat to come.
6. Insert the bombilla into the wet side, pushing it to the bottom, filter first. Once it is in, do not stir it and do not move it.
7. Pour hot water into the same wet spot, right beside the bombilla, and stop before the mountain gets wet. Sip until the gourd gurgles, then refill.
8. Keep refilling until the flavor fades, usually 10 to 20 times. When it goes flat, it is lavado (washed out). Dump it, rinse the gourd and dry it upside down.

Tereré, Chimarrão and Mate Cocido

Hot mate from a gourd is only one way to drink yerba. Three others are national institutions in their own right.

Mate Etiquette: How to Share a Gourd

Mate is almost never a solo drink in South America. It is shared, one gourd and one bombilla among everyone, and the sharing follows real rules. Break them and you will be forgiven as a foreigner, but you will be noticed.

• The cebador serves. One person prepares the mate, drinks the first (harshest) gourd, then refills and passes it. They keep serving for the whole session.
• It goes in a circle, always the same direction, and always back to the cebador between drinkers.
• Drink the whole gourd before passing it back, until it gurgles. Handing back a half-full gourd is bad form.
• Don’t touch the bombilla. Never stir with it, never adjust it. That is the cebador’s job.
• Don’t say “gracias” until you are done. In mate, “thank you” means “no more for me.” Say it too early and you are out of the rotation.
• Don’t hold it and talk. Mate is not a microphone. Drink and pass.
• Don’t wipe the bombilla before drinking. It is considered an insult to the host.

There is far more to it, including what to say when the mate is too hot, too cold or too washed out. We wrote about it in the yerba mate ritual.

Yerba Mate Health Benefits and Risks

Yerba mate has a reputation as a health drink, and some of that is earned. But a lot of what circulates online overstates what the research shows. Here is a fair summary.

What Is Reasonably Supported

• It is rich in antioxidants. Yerba mate is high in polyphenols, especially chlorogenic acid, along with saponins. Its antioxidant content is comparable to, and by some measures higher than, green tea.
• It gives sustained energy and focus. This is the caffeine and theobromine, and it is the reason most people drink it.
• It contains real nutrients. Small amounts of vitamin C, B vitamins, magnesium, potassium, zinc and manganese.
• It may help cholesterol and blood sugar. Small human studies have found modest improvements in LDL cholesterol and post-meal glucose. Cleveland Clinic describes these as promising but in need of larger trials.
• It may support exercise performance and fat burning. Several small trials found mate increased fat oxidation during moderate exercise. Weight-loss results in humans, though, are inconsistent.

What to Be Careful About

• It is caffeine. Expect the usual effects if you overdo it: trouble sleeping, jitters, fast heartbeat, heartburn, headaches. A long thermos session can add up to 300 mg or more.
• Pregnancy and breastfeeding. Mayo Clinic advises checking with a health care provider first, as with any high-caffeine drink.
• Drug interactions. Yerba mate can interact with some antidepressants (MAOIs), stimulants, blood thinners and diabetes medications. Ask a pharmacist if you take any of these daily.
• Kids. In Argentina children drink mild mate cocido with milk, but a full-strength gourd is an adult drink.

Cleveland Clinic dietitian Michela Palma sums it up well: think of yerba mate as an interesting addition to a healthy diet, not a treatment. For a deeper look at the studies, read our article on yerba mate health benefits.

Best Yerba Mate Brands for Beginners

The right first bag is an Argentine con palo yerba, ideally labeled suave. It is forgiving of water temperature, easy on the bombilla and mild enough to keep drinking. These are the five we hand people most often. All are on Amazon.

Guayakí, Yerba Madre and other American brands sell blends and canned drinks that are fine as an entry point, but they are a different (and much pricier) product from a kilo bag of Argentine yerba. Our brand comparison is in the 16 yerba mate brands.

Where to Buy Yerba Mate

Any Latin grocery with an Argentine, Uruguayan or Paraguayan shelf will carry two or three brands by the kilo. Amazon carries all of the above plus gourds and bombillas, and we keep a curated yerba mate shopping list updated with the ones we actually drink. Buy a 500 g or 1 kg bag rather than a tin; you will go through it faster than you expect.

What to Eat With Yerba Mate

Mate is the drink of the merienda, the late-afternoon snack, and of long breakfasts. It goes with anything bready, buttery or filled with dulce de leche. The classics:

• Medialunas and facturas: Argentine croissants and the whole family of bakery pastries.
• Tortas fritas: fried dough discs, sprinkled with sugar, made whenever it rains.
• Chipa: Paraguayan cheese bread, the standard companion to tereré.
• Alfajores: dulce de leche sandwich cookies.
• Sandwiches de miga: crustless tea sandwiches, for a savory merienda.
• Bizcochos, galletitas and pastelitos: the everyday crackers and pastries of an Argentine breakfast.
