How Much Caffeine Is in Yerba Mate Tea? | Caffeine Facts

You might assume yerba mate is a mild tea like green tea, but it actually packs a caffeine punch closer to coffee. It’s made from the leaves of the Ilex paraguariensis plant, and many people drink it for a more balanced energy lift.

The honest answer is that caffeine yerbamate levels vary quite a bit by brewing method, but most sources land between 70 and 85 mg per cup. That puts it right alongside an average cup of coffee and well above black tea or green tea.

How Much Caffeine Is in a Cup of Yerba Mate

Most sources report an 8-ounce serving of traditionally brewed yerba mate carries 70 to 85 mg of caffeine. Coffee typically hits around 85 mg, so they’re in the same league.

By comparison, black tea ranges from 40 to 70 mg per cup, and green tea sits lower at 20 to 45 mg. You’d need to drink about three cups of green tea to match the caffeine in one cup of mate.

The exact number depends on how long you steep it, the leaf-to-water ratio, and whether you’re using loose leaves or a tea bag. That’s why you’ll sometimes see numbers as low as 30 mg or as high as 85 mg per cup.

Why People Compare It to Coffee

Many people are surprised to learn yerba mate has roughly the same caffeine as coffee because it’s marketed as a gentler tea. The comparison comes up often, so here’s how they stack up by the numbers.

• Caffeine per 8-ounce cup: Yerba mate averages 70–85 mg, about the same as coffee’s 85 mg.
• Per 5-ounce cup: Yerba mate contains approximately 78 mg, just a hair less than coffee at 85 mg.
• Per liter: Yerba mate has around 358 mg of caffeine, while brewed coffee ranges from 386 to 652 mg per liter.
• Smoother energy: Many people report a longer-lasting alertness with fewer jitters from yerba mate because its natural caffeine is absorbed more gradually.

The key takeaway is that yerba mate offers coffee-level stimulation but often feels less aggressive. That’s why it’s become a popular alternative for people who want to cut back on coffee without losing the energy kick.

Factors That Influence Caffeine Levels in Yerba Mate

Brewing Time and Temperature

How you prepare yerba mate directly affects its caffeine concentration. A short steeping time of two to three minutes yields a milder brew, while letting it steep for five to seven minutes extracts more caffeine.

Water temperature matters too. Hotter water (around 175°F) pulls out more compounds, including caffeine. Using cooler water produces a lighter drink with lower caffeine.

WebMD notes that yerba mate also contains theobromine and theophylline, which are additional stimulants that contribute to its energizing profile in their yerba mate definition.

Beverage	Caffeine per 8 oz (approx.)	Source Note
Yerba mate (loose leaf)	70–85 mg	WebMD / Cafely
Coffee (drip)	85 mg	Common reference
Black tea	40–70 mg	Ybtco
Green tea	20–45 mg	Ybtco
Yerba mate (tea bag)	~20 mg	ECOTEAS

These numbers are averages, not guarantees. A tightly packed gourd of mate with repeated hot water infusions can deliver quite a bit more caffeine per batch than a single tea bag.

How Yerba Mate’s Caffeine Compares to Other Teas and Coffee

If you’re trying to gauge where yerba mate fits on the caffeine spectrum, the comparison with other popular drinks is useful. Most people want to know how it stacks up against their usual morning cup.

1. Compared to coffee: The caffeine content is very similar, but many drinkers report a smoother, less jittery energy from mate due to slower absorption.
2. Compared to black tea: Yerba mate is roughly twice as strong. You’d need two cups of black tea to match one cup of mate.
3. Compared to green tea: Mate contains about three to four times the caffeine. Green tea is a lower-stimulant option.
4. Compared to energy drinks: A standard 8 oz energy drink often has 80–100 mg, so mate is in a similar range but without added sugars or artificial ingredients.

The bottom line of the comparison is that yerba mate occupies a middle ground — it’s stronger than standard teas but roughly equal to coffee, depending on how you brew it.

Additional Health Notes and Considerations

Smoother Energy Claim

Many people find the energy from yerba mate feels more sustained than coffee. A Clean Cause blog notes the natural caffeine is absorbed more gradually, potentially leading to fewer jitters. The exact mechanism isn’t clearly defined in research, but it’s a common user report.

Per the average cup caffeine report from Cafely, an 8-ounce serving contains around 80 mg. This puts it in the moderate-high caffeine category, so sensitivity varies.

WebMD also flags that the caffeine in yerba mate can worsen diarrhea and might aggravate IBS symptoms. It may also increase calcium loss through urine, which is a consideration for bone health. A small study suggests it might help support blood sugar management in diabetes, but more research is needed.

IBS caution	Caffeine may worsen symptoms	WebMD

These notes aren’t meant to scare anyone away, but if you have a sensitive stomach or are watching your calcium intake, it’s worth testing how yerba mate treats you in smaller amounts first.

The Bottom Line

Yerba mate delivers about 70 to 85 mg of caffeine per 8-ounce cup, putting it in the same range as coffee but generally with a gentler vibe. It’s significantly stronger than black or green tea, so treat it more like a coffee substitute than a mild tea.

Your primary care provider or a registered dietitian can help you decide if yerba mate fits your personal caffeine goals, especially if you have IBS or concerns about bone density.
