Check price →Read review ↓The short answer: the best yerba mate for cold brew (tereré) is Guayakí Organic Traditional loose leaf — smooth, low-dust, organic, and easy to find, which makes it the most forgiving leaf to drink ice-cold. If you want truly unsmoked and clean, Kraus is the pick; if you want the authentic Paraguayan tereré experience, reach for Pajarito, Paraguay's favorite.
Tereré is simply yerba mate drunk cold — packed in a cup or guampa and steeped with ice-cold water or fruit juice instead of hot water. It's the everyday way mate is consumed in Paraguay (and much of northern Argentina) in the heat, and it's having a moment elsewhere as a refreshing, caffeinated iced drink. One underrated bonus: because tereré is cold, it sidesteps the one well-documented caution around mate entirely — the temperature one (more on that below).
The leaves that shine cold are the smooth, low-dust ones: cold water extracts more slowly and less forgivingly than hot, so a clean, large-leaf, low-bitterness mate makes the best tereré. We rank on exactly that, and everything below is a real, currently-sold product.
The short version
- Best overall for cold brew: Guayakí Organic Traditional loose leaf — smooth, low-dust, organic, the most forgiving leaf to drink cold.
- Best unsmoked/clean: Kraus organic unsmoked — genuinely smoke-free and green, so nothing muddies a cold cup.
- Best authentic tereré: Pajarito Tradicional — Paraguay's favorite, the leaf tereré is traditionally made with.
- Tereré = yerba mate drunk cold, steeped with ice water or fruit juice instead of hot water — the Paraguayan tradition.
- Cold sidesteps the temperature caveat: the IARC's very-hot-beverage caution (above 65°C/149°F) doesn't apply to cold tereré.
- Smooth, low-dust leaves make the best tereré — cold water extracts slowly, so a clean, large-leaf mate beats a fine, powdery one.
| Product | Origin | Smoke | Cut | Best for |
|---|---|---|---|---|
| Guayakí Loose Leaf | Argentina (organic) | Unsmoked (air-dried) | Smooth, low-dust | Most forgiving cold |
| Kraus Unsmoked | Argentina (organic) | Truly unsmoked | Clean, low-dust | Cleanest cold cup |
| Pajarito Tradicional | Paraguay | Lightly smoked, aged | Smooth, aged | Authentic tereré |
The best yerba mate for cold brew (tereré) — smooth, low-dust leaves win cold.

First things first — what are you after with yerba mate?
01 · Best Overall for Cold Brew
Our PickOrganic Traditional Loose Leaf
Smooth, low-dust, organic, and everywhere — the most forgiving leaf to drink ice-cold.
Lab report: USDA Organic, air-dried (unsmoked) con-palo Argentine yerba mate. Rainforest-grown, widely available loose leaf.
Cold water is less forgiving than hot — it extracts slowly and pulls bitterness unevenly — so the best tereré leaf is a smooth, clean, low-dust one, and Guayakí's Organic Traditional fits exactly. It's air-dried (unsmoked), con palo (with stems, which keeps it mellow), USDA Organic, and the cut is clean enough that it won't turn your cold cup harsh or clog the bombilla.
It's not the most traditional Paraguayan choice (that's Pajarito, below), and experienced drinkers may want something bolder. But for sheer ease and availability when you're learning to drink mate cold, nothing beats it.

What we like
- Smooth and low-dust — ideal cold
- Unsmoked, clean base flavor
- USDA Organic
- Available almost everywhere
Worth noting
- Not the traditional Paraguayan choice
- Milder than bolder leaves
- Stems mean less raw strength
Who should buy it: Anyone trying cold brew or tereré for the first time who wants a smooth, forgiving, organic leaf that's easy to find.
What we don't like: It's not the authentic Paraguayan tereré leaf, and seasoned drinkers may find it milder than they'd like.
Bottom line: Guayakí's Organic Traditional is the easiest leaf to recommend for cold brew. It's smooth, low-dust, unsmoked, organic, and available almost everywhere — which makes it the most forgiving choice when you're steeping cold, where harsher leaves turn bitter. If you're trying tereré for the first time, start here.
02 · Best Unsmoked / Cleanest Cold
Organic Unsmoked Yerba Mate
Genuinely smoke-free and green — nothing muddies the crisp clarity of a cold cup.
Lab report: Certified organic, indirect-hot-air-dried (genuinely unsmoked) Argentine yerba mate. No smoke, no added flavor.
Most "traditional" mate is dried over a wood fire, which leaves a smoky note. Kraus is indirect-hot-air-dried — genuinely unsmoked — so the base flavor is clean, green, and unmuddied. Cold brewing tends to spotlight a leaf's underlying character, and Kraus's character is purity: nothing smoky, nothing harsh, just crisp green mate over ice.
It's a more specialist (and pricier per gram) choice than the everyday Guayakí, and it isn't the traditional Paraguayan tereré leaf. But for a clean, smoke-free cold cup, it's the best in this lineup.
- Origin
- Argentina
- Smoke
- Truly unsmoked (hot-air dried)
- Certified
- Organic
- Flavor
- Clean, green, no smoke
- Where to buy
- Amazon
What we like
- Genuinely unsmoked — crisp cold
- Clean, green base flavor
- Certified organic
- Refreshing over ice
Worth noting
- Pricier per gram
- Not traditional Paraguayan tereré
- Specialist rather than everyday
Who should buy it: Drinkers who want a genuinely smoke-free, crisp, clean cold cup and don't mind paying a little more for purity.
What we don't like: Pricier per gram than everyday leaf, and it isn't the authentic Paraguayan tereré choice.
Bottom line: Kraus is the gold standard for truly unsmoked mate, and that pays off cold: with no smoky note to muddy it, a cold cup reads crisp and clean. It's the pick if you want tereré that tastes purely of green leaf, nothing else.
03 · Best Authentic Tereré
Tradicional (1kg)
Paraguay's favorite — the long-aged, smooth leaf tereré is traditionally made with.
Lab report: Paraguayan yerba mate, long-aged, lightly smoked. The country's best-selling brand; sold by the kilogram.
Tereré is Paraguay's drink, and Pajarito is Paraguay's leaf — the country's best-selling brand. It's long-aged and only lightly smoked, which gives it a smooth, mellow profile that holds up beautifully cold. This is the mate that millions of Paraguayans pack into a guampa and steep with ice water (often with herbs, or yuyos, muddled in) through the heat of the day.
It comes by the kilo, so it's a commitment of volume (though great value per gram), and the light smoke means it's not quite as crystal-clean as Kraus. But for traditional, everyday tereré, it's the most authentic pick here.

- Lightly smoked

- Long-aged
- Format
- 1kg bag
- Where to buy

What we like
- Paraguay's #1 — authentic tereré leaf
- Long-aged and smooth
- Holds up well cold
- Great value per gram
Worth noting
- Only in large kilo bags
- Lightly smoked (not crystal-clean)
- Large commitment of volume
Who should buy it: Anyone who wants the authentic Paraguayan tereré experience with the leaf the tradition is actually built on.
What we don't like: It only comes in large kilo bags, and the light smoke makes it less crystal-clean than a truly unsmoked leaf.
Bottom line: For the real, authentic tereré, reach for Pajarito — Paraguay's most popular yerba mate, and tereré is Paraguay's national drink. It's long-aged and smooth, the leaf countless Paraguayans drink ice-cold every day. If you want tereré done the traditional way, this is the source.
How to make tereré (cold-brewed yerba mate)
- 1
Fill the cup
Pack a guampa or cup about two-thirds full with a smooth, low-dust yerba mate. Tilt it to bank the leaf to one side, leaving a small hollow at the low edge.
- 2
Chill your liquid
Use ice-cold water — or, for the classic Paraguayan version, cold fruit juice (lemon, orange, or pineapple are common). Some drinkers muddle in fresh herbs (yuyos) like mint. No hot water at all.
- 3
Wet the low spot
Pour a little of the cold liquid into the hollow first, then insert the bombilla (filtered straw) into that wet low spot so it doesn't clog.
- 4
Top up and steep
Fill the cup the rest of the way with the cold liquid. Because it's cold, extraction is slower — give it a moment to steep, then drink through the bombilla.
- 5
Refill and share
Refill with cold liquid many times; the leaf keeps giving for numerous rounds. Tereré is traditionally shared, the cup passed around the circle. No need to let it cool — it's already cold, so the temperature caveat never applies.
How we chose
We rank yerba mate for cold brew on how well the leaf performs cold: smoothness and low bitterness (cold water extracts harsh notes unevenly, so a forgiving leaf matters most), cut and dust level (large-leaf, low-dust mate steeps cleaner cold and clogs a bombilla less), and how clean the base flavor is (unsmoked and well-aged leaves read crisper over ice). We also factor authenticity — Paraguayan leaf for traditional tereré — and value, since this is a daily-drunk staple.
A note on health framing: yerba mate is a caffeinated beverage, not a supplement or a treatment. It naturally contains caffeine (commonly ~30–50mg per ~8oz brewed serving). The one well-documented caution around mate is temperature, not the leaf — the IARC classifies drinking *very hot* beverages above 65°C (149°F) as probably carcinogenic, a risk historically tied to drinking scalding mate through a metal straw. Tereré is the cold preparation, so it sidesteps that caveat entirely — there's no scalding water involved. This isn't medical advice.
Questions, answered
What is the best yerba mate for cold brew?
Guayakí Organic Traditional loose leaf, for most people — it's smooth, low-dust, unsmoked, and organic, which makes it the most forgiving leaf to drink ice-cold. For a genuinely unsmoked, crisp cup, Kraus is the pick; for authentic Paraguayan tereré, Pajarito (Paraguay's favorite) is the traditional choice.
What is tereré?
Tereré is yerba mate drunk cold — packed in a cup or guampa and steeped with ice-cold water or cold fruit juice instead of hot water, then sipped through a bombilla. It's the everyday way mate is consumed in Paraguay and northern Argentina, especially in the heat, and it's often shared around a circle.
Can you cold brew yerba mate?
Yes — that's exactly what tereré is. Pack a cup about two-thirds with smooth, low-dust yerba mate, wet the low spot first, insert the bombilla, then fill with ice-cold water or cold juice. Because cold water extracts more slowly, a clean, smooth leaf works best and you can refill many times.
Is cold-brewed yerba mate safer than hot?
On the temperature point, cold preparation avoids the one well-documented caveat. The IARC's caution about mate is specifically about drinking it very hot — above 65°C (149°F) — not about the leaf. Tereré is steeped cold, so there's no scalding liquid and that caveat doesn't apply. It still contains caffeine, so mind your total intake. This isn't medical advice.
What's the difference between cold-brewed mate and tereré?
They're essentially the same thing — tereré is the traditional name for yerba mate prepared cold. "Cold brew" is just the English framing. Classic tereré often uses cold fruit juice and muddled herbs (yuyos) rather than plain water, but both refer to steeping mate cold instead of hot.
Do you need special yerba mate for tereré?
Not special, but a smooth, low-dust leaf works best. Cold water extracts slowly and less forgivingly than hot, so a clean, large-leaf, low-bitterness mate (like Guayakí or Pajarito) makes a better cold cup than a fine, powdery, intense one, which can taste harsh and clog the bombilla when chilled.
