Yerba Mate Loose Leaf Tea

Yerba Mate Tea: What is it and why is everyone talking about it?

Posted by Stephany Morgan


Yerba Mate, a traditional South American drink, has gained so much popularity that it can be found in everything from energy drinks to mate lattes. I've also seen it mentioned more and more However, there are still a lot of misconceptions about this delicious traditional beverage.

In this article, I'm going to share:

 

  • What is yerba mate tea? Where does it come from?
  • How much caffeine is in yerba mate + why it's different from coffee
  • The health benefits of yerba mate tea
  • How to brew yerba mate & what it tastes like, with traditional vs modern, hot vs cold brewing
  • Yerba mate recipes, to drink and to eat!
  • Myth-busting: yerba mate + cancer. Is it safe to drink?
  • Why yerba mate is a true superfood

 

What Is Yerba Mate?

Yerba mate comes from the evergreen shrub Ilex paraguariensis. Indigenous peoples across South America traditionally consumed an infusion of this plant as a delicious beverage to help combat fatigue and to settle gastrointestinal discomfort. It is still an extremely popular drink today too (Taylor, 2005). 

It is a member of the holly family, though not quite like your typical Christmas decorations! For one, its leaves aren't prickly, and it also only grows in Argentina, Brazil, Paraguay and parts of Chile.

Yerba mate has a smooth, woody taste; somewhat similar to green tea, but richer and more herbaceous. 

Since "yerba mate" is a term created by Spanish-speaking countries, "mate" has two syllables. Thus, you pronounce it as "yer-ba ma-tay."

Yerba Mate Caffeine Content - How much?

Some sources suggest that yerba mate contains no caffeine, but rather a chemically-similar compound called “mateine”. However, this is pure semantics! 

Mateine is a synonym for caffeine, and they are chemically identical. Yerba mate contains almost the same amount of caffeine as a cup of coffee, in addition to theobromine and theophylline.

In small amounts, these latter two chemicals prevent jitters, settle the stomach, and promote muscular relaxation. In large amounts, they can act similarly to caffeine and have a stimulating effect. 

Mate can contain up to 85-90 mg of caffeine per 8 oz cup! For that reason, and due to other phytochemicals, it is a popular substitute for coffee (which contains 95 mg of caffeine per 8 oz cup) (Petre, 208). (Here's a handy list we made of caffeine levels of other popular drinks and teas)

Caffeine Molecule

As with coffee, though, it is best to drink no more than 3-4 cups of yerba mate per day.

From our own experience, and the reviews and feedback from our customers, mate doesn't give the 'coffee jitters,' and also doesn't cause the dreaded 'coffee slump' where you crash an hour after having a cup of joe. Instead, we've found it helps with steady concentration and alertness throughout the day. Yay antioxidants, combining for a great energy drink!

The Health Benefits of Yerba Mate Tea

Yerba mate is a panacea of goodness! Full of minerals like zinc, potassium, iron and vitamins B1, B2 and C, it makes for a nutritious beverage (Petre, 2018).

Yerba mate also contains saponins - a group of compounds that decrease blood lipids, lower blood glucose response, decrease cancer risk, and are commonly found in adaptogenic herbs (Herb Wisdom, 2022; Akaripour, 2014). (If you're not sure what those are, check out my post about adaptogens!)

Mate is anti-inflammatory and full of antioxidants, scoring a 1700 on the ORAC scale (for comparison, matcha clocks in at 1384 and green tea at 1253). For more info about the ORAC scale and how it measures antioxidants, read my post on the subject.

 

Some of yerba mate's main health benefits include:

    • Can stimulate immune cells, to help prevent infections, such as skin rashes and food poisoning, as well as boosting your immune system due to its anti-inflammatory properties (Petre, 2018)
    • Pain relief, with tradtional use for treating nerve pain and rheumatic pain, and headaches (Herb Wisdom, 2022)
    • Helping with allergies by reducing inflammation (Ibid)
    • Helping with arthritis, again by reducing inflammation (Ibid) 
    • Can help with obesity by reducing the appetite, increasing metabolism and some research suggests mate even decreases total number of fat cells, and how much fat each cell can store. Plus it helps burn more energy thanks to its high caffeine levels (Petre, 2018)
    • Mentally, mate may help boost memory, focus and cognition. Mate's antioxidants can help reduce or avoid plaque deposition in the brain, which could help prevent dementia (Nagdeve, 2020)
    • Helps prevent and manage iron deficiancy, as well as improve blood circulation, as mate contains high iron levels  (Wrobel, 2000)
    • The antioxidants in yerba mate can help prevent early aging, cell death, and DNA damage (Nagdeve, 2020)

 

In short, yerba mate's antioxidants do some amazing things! As with all teas and tisanes, it is an ideal addition to your normal tea routine, so you can enjoy mate's antioxidants and caffeine alongside your other brews. A varied and balanced diet applies to teas as well as food! ;-)

How to Brew Yerba Mate & What Does Mate Taste Like?

There are three main ways to brew mate. In all cases, remember that mate burns easily, so be gentle when brewing it! 

 

What does is the flavor of yerba mate?

  • Unroasted green mate tastes beautiful: Soft, lightly roasted, no bitterness or astringency, smooth, with a lemon-like aftertaste, it is almost minty and cooling. If you brew it in too-hot water, though, it can go bitter.
  • Roasted mate has a completely different flavor profile: Soft, sweet, like maple syrup, with no bitterness and strong notes of caramel and brown sugar.
  • Mate in teabags: Because the leaves are ground up into a fine dust, they release all their flavor very quickly and it is hard to brew teabag mate without it going bitter. It tends to have a stronger taste than looseleaf green mate, because every single part of the leaf is brewing instantly. Top tip: avoid mate in teabags! (Plus, it's better for the environment, win-win)

We use these two mates above as the bases for all our mate blends, depending on if we want a light lemony flavor or richer, more wintery notes. 

 

Modern Mate Brewing

These steps will make sure you end up with the perfect mate tea, without any special equipment:

 

  • Pour a small splash of cold water over 1-2 tsp of the loose leaves in your tea strainer, just enough to completely wet them. This protects them from being scalded.
  • Steep the leaves in 8 oz (one mug) of water that has just started simmering (100-170F) for 2-3 minutes. Don't let the water boil - otherwise, you'll burn the fragile leaves, destroying their nutrients and giving them a bitter taste.
  • If you don't have a thermometer, take your kettle off the boil when it starts to simmer. When you pour it, hold the kettle up high to maximize how far the water needs to fall before it hits your leaves. 

 

Traditional Mate Brewing

The traditional way of preparing mate is in a hollowed out gourd (and very traditionally consumed over time as part of the 'ronda del mate' ceremony). The leaves stay in the tea as you drink it, and are filtered out via the bombilla, a straw with a filter at the end. The bombilla was traditionally made with hollow stalks, but now it is more common to find metal or bamboo bombillas. 

First, fill your gourd halfway with looseleaf yerba mate. Then, pour a little cold water over the leaves to moisten them (this also protects them from burning). Tilt the gourd on its side and tap it so the leaves fall to one side into a mound. Put your bomilla (straw) into the non-mounded side.

Now it's time for your hot water: Pour non-boiling water (100-170F) about halfway up the gourd. The top of the leaves should remain dry and uncovered!

Sip the mate through the straw until there's no more tea, then refill with your hot water and repeat. If you are with a group of friends for the Ronda del Mate, you drink the mate, refill, pass the gourd to your neighbor, they drink, and repeat.

How to Brew Iced Yerba Mate 

For iced mate, you have two methods:

A) Hot Brew Iced Mate

Follow the same approach as for hot brewing above, but triple the quantity of tea used and double the water. Let it steep for at least twenty minutes. Then put it in the fridge, or pour directly over ice and enjoy.

Antioxidants tend to disappear within 3-4 hours of brewing in hot water, so be sure to drink your iced mate promptly if you're after the antioxidants! The caffeine on the other hand doesn't degrade, so it will stay caffeinated until you drink it.

 

B) Cold Brew Yerba Mate

You can make cold brew yerba mate by putting the leaves in cold water overnight, with the result of a 'cleaner', rounder flavor. Plus, the antioxidants will last a lot longer, as they haven't been damaged by hot brewing (antioxidants are very susceptible to heat, so cold brewing can yield an antioxidant-rich tea that will keep its goodness for up to a few days in the fridge).

When you serve, simply pour through a sieve or, better yet, brew using a stainless steel teaball so you can simply remove it.

Does Yerba Mate Cause Cancer? Are there any risks?

There are questions and articles circulating about the rumor that yerba mate causes cancer. So let's dive in to myth-bust this fear-mongering!

The studies that started this rumor all connected drinking large amounts of scalding mate, plus smoking, plus drinking alcohol to an increase in certain types of cancer (Loria, 2009). By large amounts, I mean 1+ liters of extremely hot mate a day!

When such specific circumstances are met for consuming any hot liquid, such as yerba mate, the studies showed there can be an increased risk for certain kinds of cancer, due to burning and scalding the throat (Ibid). 

Scalding your own throat like an obvious thing to avoid anyway, but of course everything needs to be investigated!

Which is exactly what a team from the Institute of Oncology in Buenos Aires did: they did an enormous review of all studies looking for links between yerba mate and cancer. They found that across existing studies, the chance of cancer of esophagus, larynx, and oral cavity was increased for heavy smokers and drinkers who also regularly drank 1+ liters of scalding hot yerba mate a day (Ibid). 

So consuming large amounts of tea for prolonged amounts of time at very hot temperatures (149F+ when it actually hits your esophagus), can increase the risk for certain cancers.

This is a seriously scalding drink, by the way! Your normal cup of black coffee or tea or yerba mate is somewhere between 120-140F when you drink it.

And, as we just learned, mate is *brewed* at temperatures between 100-170F. It will, of course, start to cool even more by the time you drink it - you have to drink it really fast to even get to it when it's still so hot.

They theorized that the increased risk of cancer is due to the temperature of the liquid itself, burning and damaging the tissue, and then providing access for the carcinogens in tobacco and alcohol. 

Simply put, yerba mate happened to be the hot beverage investigated due to its popularity across South America, but the researchers found no connection between the type of tea and cancer risk. Taken cold, yerba mate showed zero increase in cancer risk, indicating that temperature is the defining factor across these studies (Ibid).

In short, rest easy, yerba mate lovers!

Is Yerba Mate the Next Superfood?

I certainly think so! Its health benefits, tonic action, immune support and nutritional value make yerba mate tea a valuable and delicious addition to the diet.

Mate is incredibly high in antioxidants, including xanthines (caffeine, theobromine), caffeoyl, saponins and polyphenols/phenolic compounds. These are different from the antioxidants found in Camellia sinensis (i.e. tea!) and have been shown to have multiple health benefits (see above list for details) (Nagdeve, 2020). 

Yerba mate has a rich history of traditional medicinal use, and is a healthy, safe, and beneficial drink ... unless you literally burn yourself with it (don't do that, please).

For all the details about what the antioxidants in yerba mate are and do, read my article covering that here.
