Check price →Read review ↓Short answer: yes, Guayakí is worth it — and for most Americans it's the best first yerba mate to buy. It's smooth, USDA Organic, Fair Trade, air-dried (unsmoked), and con palo (with stems), which is the exact combination that makes mate easy to like. It's also the one mate you can find at almost any grocery store, so you're never stranded.
Guayakí is the brand that introduced most of the US to yerba mate, and you'll now see the same company on shelves as 'Yerba Madre' — it's a rebrand, not a different mate. This review covers the three ways you can buy it: the loose leaf (the real thing, brewed in a gourd), the tea bags (no gear, no learning curve), and the cans (sweetened, ready-to-drink energy).
We rank on what's in the bag and how it's made — stems, smoke, origin, and certification — not on marketing. Here's where Guayakí earns its reputation, and where a kilo of imported Argentine leaf or a truly smoke-free brand like Kraus does it better.
The short version
- Worth it for: beginners and anyone who wants a smooth, unsmoked, certified-organic daily mate that's sold everywhere.
- The lead pick is the Organic Traditional loose leaf — air-dried (unsmoked) and con palo, so it's forgiving and clean-tasting.
- Tea bags are the no-gear way in: organic, unsmoked, unsweetened, ~40mg caffeine per bag — brew in any mug.
- Cans (Revel Berry, etc.) are sweetened ready-to-drink energy — convenient, but a different product from the loose leaf.
- Skip it if you want maximum strength (go Uruguayan/sin palo) or the cheapest per-serving cost (buy a 1kg import).
- Caffeine: loose-leaf ~30–50mg per ~8oz; the cans run higher, around 120–160mg. Let any hot mate cool below scalding (IARC flags very-hot drinks above 65°C/149°F).
| Format | Best for | Sweetened | Caffeine | Price |
|---|---|---|---|---|
| Organic Traditional loose leaf | The real gourd ritual | No | ~30–50mg / serving | $13–$18/lb |
| Organic tea bags | No-gear, no learning curve | No | ~40mg / bag | $10–$16/75ct |
| Revel Berry cans | Ready-to-drink energy | Yes | ~150mg / can | $30–$45/12pk |
Guayakí's three formats — same organic, unsmoked mate, very different experiences.

Question 1 of 6
First things first — what are you after with yerba mate?
01 · Best Overall — the format to start with
Our PickOrganic Traditional Loose Leaf
Smooth, unsmoked, organic, and everywhere — the mate that's both beginner-safe and genuinely good.
Lab report: USDA Organic and Fair Trade, rainforest-grown. Argentine style, con palo (with stems), air-dried/unsmoked. Now also sold as 'Yerba Madre.'
Most imported traditional mate is dried over a wood fire, which gives it a smoky, campfire note that newcomers either love or bounce off. Guayakí's traditional loose leaf is air-dried (unsmoked), so it's clean and green instead, and it's con palo — blended with stems, which mellows the brew and makes it more forgiving if you pour a little too hot or pack the gourd a little too full.
It brews well in a gourd or a French press, and the smooth profile is the right first impression of what mate can be. As a beverage it naturally contains caffeine (~40mg per serving by the brand's own measure) — let it cool below scalding before you drink.

What we like
- Smooth and beginner-friendly
- Unsmoked — clean, green flavor
- USDA Organic + Fair Trade
- Stocked almost everywhere
Worth noting
- Milder than bold traditional mates
- Costs more per pound than 1kg imports
Who should buy it: Almost anyone — first-timers who want a smooth, no-smoke introduction, and regulars who want a clean organic daily leaf they can buy anywhere.
What we don't like: It's milder than a bold Argentine or a stemless Uruguayan mate, so seasoned drinkers chasing intensity will want something stronger. Per-pound it costs more than the big imported 1kg bags.
Bottom line: If we could keep only one mate in the cupboard, this is it. Guayakí pairs the two things that make mate easy to love — air-drying (no smoke) and stems (a smoother, more forgiving cup) — with organic certification and grocery-store availability. It's the safest great place to start.
02 · No-Gear Option
Organic Traditional Tea Bags
Organic, unsmoked mate in a tea bag — no gourd, no bombilla, no learning curve.
Lab report: Argentine, USDA Organic, unsmoked, unsweetened. ~40mg natural caffeine per bag.
The gourd-and-bombilla ritual is wonderful, but it's also a barrier. These tea bags remove it entirely: drop one in a mug of hot (not boiling) water, steep, and you're drinking the same organic, unsmoked mate as the loose leaf — just milder, and without the endless refills.
Let it cool below scalding before drinking, as with any hot mate.

- Argentina
- Smoke
- Unsmoked
- Sweetened
- No (unsweetened)
- Caffeine
- ~40mg / bag
- Where to buy
- Amazon
What we like
- No gear required
- Organic and unsmoked
- Unsweetened — real mate flavor
- The easiest way to try Guayakí
Worth noting
- Milder than a gourd
- Less economical than loose leaf
- No refills / no ritual
Who should buy it: Total beginners and office/travel drinkers who want real Guayakí mate with no gear and no learning curve.
What we don't like: A bag is milder and less economical than loose leaf in a gourd, and you miss the ritual and the refills.
Bottom line: If you want to taste mate without buying a gourd and learning to pack it, start here. The tea bags are organic, unsmoked, and unsweetened — steep one in any mug and you've got real Guayakí mate with zero equipment.
03 · Ready-to-Drink Energy
Revel Berry Cans
Sweetened, berry-forward mate energy in a can — convenient, but a different product from the leaf.
Lab report: Ready-to-drink, organic, fruit-sweetened. Roughly 150mg caffeine per 15.5oz can (the brand's most popular RTD flavor).
The cans solve a real problem: you can't brew a gourd at your desk or in the car. Revel Berry is the most popular flavor — bright, berry-forward, and noticeably sweet — with roughly 150mg of caffeine per can, which lands in energy-drink territory. As a cleaner, organic swap for soda or a chemical energy drink, it does the job.
For a zero-sugar canned option, Mateina is the cleaner pick; for sparkling, CLEAN Cause. Revel Berry is the sweet, fruity one.

- Caffeine

- Amazon
What we like
- Organic ready-to-drink energy
- Tasty, berry-forward flavor
- Portable — no brewing
- A cleaner energy-drink swap
Worth noting
- Sweetened
- Expensive per serving
- Not the real gourd experience
Who should buy it: People who want mate's caffeine on the go and don't mind sweetness — a cleaner, organic energy-drink alternative.
What we don't like: It's sweetened and pricey per serving, and it loses the ritual, the refills, and the clean unsweetened flavor of brewed mate.
Bottom line: Guayakí basically created the canned-mate category, and Revel Berry is its signature: a sweet, fruity, organic energy drink built on mate. It's the convenience play — tasty and portable — but it's sweetened and worlds apart from a fresh gourd of loose leaf.
How we chose
We bought and brewed Guayakí across its three formats — loose leaf in a gourd, tea bags in a mug, and cold cans — and judged each on the things that actually define a mate: stems (con palo vs sin palo), smoke (wood-fire vs air-dried), origin and cut, and certification (organic, Fair Trade). Then we weighed value per serving against the imported 1kg bags it competes with.
Health framing, kept honest: yerba mate is a caffeinated beverage, not a supplement or a treatment, and we make no health claims for it. It naturally contains caffeine (loose-leaf commonly ~30–50mg per ~8oz; the cans are dosed higher). The one well-documented caution is temperature, not the leaf: the IARC classifies drinking *very hot* beverages above 65°C (149°F) as probably carcinogenic — historically tied to drinking scalding mate through a metal straw. The fix is simple: don't drink it scalding.
Questions, answered
Is Guayakí worth it?
For most people, yes — especially as a first mate. It's smooth, USDA Organic, Fair Trade, air-dried (unsmoked), con palo, and sold almost everywhere, which is the exact recipe for an easy-to-like, dependable daily mate. It's worth it less if you're a heavy daily drinker chasing the lowest per-serving cost (buy a 1kg import) or maximum strength (go Uruguayan/sin palo).
Why is Guayakí now called Yerba Madre?
It's a rebrand by the same company, not a different product. You may see the older 'Guayakí' name and the newer 'Yerba Madre' name on shelves and online; the mate inside — Argentine, organic, unsmoked, con palo — is the same. Don't overthink which name you grab.
Is Guayakí yerba mate smoked or unsmoked?
Unsmoked. Guayakí's traditional mate is air-dried rather than dried over a wood fire, so it's clean and green instead of smoky. That's a big part of why it's so beginner-friendly — if you've tried other mate and disliked the campfire flavor, smoke was likely the reason, and Guayakí avoids it.
How much caffeine is in Guayakí?
It depends on the format. The loose leaf brewed in a gourd is in the usual mate range of roughly 30–50mg per ~8oz serving (though you refill many times), and the brand cites about 40mg per tea bag. The cans are dosed much higher — around 150mg per can — because they're built as energy drinks.
Is Guayakí good for beginners?
Yes — it's our top beginner pick. The combination of unsmoked (no campfire flavor) and con palo (stems make it smoother and more forgiving), plus organic certification and easy availability, makes it the gentlest, lowest-risk introduction to real yerba mate. Start with the loose leaf or, if you don't want gear yet, the tea bags.
Is Guayakí bad for you?
Guayakí is a widely-enjoyed caffeinated beverage, not a supplement, and we make no health claims for it. The one well-documented caution is temperature: the IARC classifies drinking *very hot* beverages (above 65°C/149°F) as probably carcinogenic, a risk tied to the heat — historically to drinking scalding mate through a metal straw — not to mate itself. Let it cool below scalding, moderate your caffeine, and be mindful if you're pregnant or caffeine-sensitive. This isn't medical advice.
