Yerba Mate: History, Benefits, Side Effects, And How To Make It

How does a South American drink take off like wildfire, becoming a buzzword in tearooms worldwide? It’s not the drink itself that’s catching a craze; it’s the unique way tea drinkers enjoy it and the benefits it delivers that fuel the hot trend of this potent tisane.

What Is Yerba Mate?

Yerba mate tisane (herbal tea) is made from parts of the yerba mate plant (Ilex paraguariensis.) This plant belongs to the holly family and is native to parts of Asia and South America. Most yerba mate plants are cultivated as understory plants in the wild. 

Where Did Yerba Mate Come From?

The yerba mate drink is a tea rooted in Paraguay; however, it grows in tropical areas in northern Argentina, south Brazil, Uruguay, Paraguay, and Asia. It has a rich history that adds to the mystique of this tea.

There are several theories on what “yerba mate” translates to. One mentions it got its name from a combination of Spanish and the language of Quechua people (Indian people of Peru, Bolivia, Chile, Colombia, and Ecuador), which translates to “calabash herbs” (calabash is a South American gourd.) 

The other theory claims yerba mate got its name from the Guarani Indians. The gourd used by the Guaranis to drink the tea translates to “water” in their language. It was the Quechua people who dubbed “mate” as “cup” in their language. 

Likewise, the Aztec people chimed in with their term for “mate” by using a gourd to drink from (known as “hahuatl tecomatl” meaning “solid container.”)

The South American Guarani Indians were the first on record to create a tea from yerba mate. Although the exact time of this occurrence is not known, it is speculated to have happened during the late 15th to early 16th century.  

Regardless of the various claims, the tea was termed “yerba mate” by Spanish conquerors who arrived in South America in the 16th century. 

By the 1670s, cultivation of the yerba mate plant began, which later came to ruin by the dissolution of the monks who ran them. It wasn’t until the early 1900s that cultivation was up and going again. Today, there are three countries (Argentina, Brazil, and Paraguay) honing in on growing, processing, and exporting yerba mate. 

Modern ready-to-drink (such as Guayaki Yerba Mate,) tea bag yerba mate, and fine loose-leaf yerba mate is an integral part of most any tea retail.

How To Drink Yerba Mate – Cultural Traditions

How To Drink Yerba Mate

It helps to know a few relative terms used in the yerba mate tea culture. 

  • Matero – the vessel yerba mate is prepared in and consumed from.
  • Bombilla – a tube (straw) with a filter at the bottom that yerba mate drinkers sip the tea through.
  • Cocido or Chimarrao – hot brew of yerba mate
  • Terere – cold brew of yerba mate
  • Cebador – the ceremonial act of sharing yerba mate from one matero with friends or guests.

Customs in the various South American natives depict how yerba mate is prepared and consumed. No matter what tribe or country one belongs to, yerba mate is often shared ceremonially (cebador) among others as an act of hospitality. 

Traditional Yerba Mate

There are two traditional ways yerba mate drinkers enjoy their tea, and depending on where someone is from; it may be a hot or cold brew tea. 

“Mate Cocido” or “Mate Chimarrao” – Hot Brew

This is the traditional way of consuming yerba mate by South Americans. The tea is prepared (brewed) in a “matero” (calabash gourd or a wooden or porcelain vessel.) Dried tea leaves are placed inside the matero, and hot water is added. The tea inside the matero is steeped for about 5 minutes.

A “bombilla” (tube-like straw) is inserted into the matero. While sipping through the bombilla, the filter at the bottom of the tube filters out the tea leaves/particles.

“Terere” – Cold Brew

Paraguayans and Brazilians prefer yerba mate cold. The tea leaves are placed in the matero, and cold water is added—the tea steeps for a few minutes. Next, the bombilla is inserted. Before drinking the tea, citrus fruit is often added to the tea.

Modern Yerba Mate

While drinking yerba mate from a gourd may offer a rustic, traditional quality to teatime, there are other ways to enjoy this tisane (herbal tea) in a more contemporary fashion. Tea producers process yerba mate in tea bag form to make it more convenient to enjoy. It’s also available as a loose-leaf tisane.

What Does Yerba Mate Taste Like?

Now we get to the meat of the article, where the dying question of what this tisane tastes like. Expectations are usually within the earthy range because it does, after all, come from an herbaceous plant. 

Envision all of the attributes of a dense subtropical forest bottled up into a myriad of tastes. The canopy of the thick trees above and the vegetation that carpets the forest floor tickle the palate with an intriguingly earthy, bitter, sweet flavor. The fresh, woody element of the terroir adds a nice finish to every sip.

Not all yerba mate tisanes are going to have the same taste. Terroir (where it’s cultivated) differs because of climate and elevation. Some may be higher in tannins, imparting a bit more bitterness, while others are more toasty.

The way the tea is processed plays a vital role in the taste of the tea as well. 

How Is Yerba Mate Processed?

The leaves of the yerba mate plant are harvested during certain months according to where it is cultivated. One country may harvest early spring to late summer, while others may opt for late winter to late summer or summer harvesting.

While there is a basic method used in processing, there may also be minor differences applied to the method because of the region or culture processing it.

Processing Method

  • Once the leaves/stems are harvested, they are brought back to a building to be processed.
  • To stop oxidation, the leaves/stems are briefly heated. This may be in an oven, open fire or hot air dryer.
  • The tea leaves/stems are allowed to cool.
  • Next, they go on to be dried in chambers where heat is produced by burning wood. This lasts for up to 24 hours.
  • The dried tea leaves/stems are then crushed.
  • Now, it’s time for storage for up to a year, where the tea ages and produces its well-known concentrations of phenols.
  • Upon coming out of storage, the tea may go through sorting to distribute stems to leaves evenly or be infused with citrus.
  • The finished yerba mate goes on to be packaged (tea bags or loose-leaf) and sent to market.

Yerba Mate Caffeine

According to a research article in the Nutrients Journal, a cup of yerba mate yields about 80 mg of caffeine (about the same as a cup of coffee.) Caffeine in yerba mate plants will, of course, vary depending on how it was processed and if the plant is male or female. Female plants have less caffeine.
