Short answer: a typical cup of yerba mate contains around 70-85mg of caffeine, slightly less than a cup of brewed coffee (about 95mg) and roughly double a cup of black tea (about 40mg). But the number only tells half the story. Here's the full picture.
Caffeine comparison: yerba mate vs everything else
- Yerba mate (250ml cup): 70-85mg
- Brewed coffee (250ml): 90-100mg
- Espresso (single shot): 60-75mg
- Black tea (250ml): 40-50mg
- Green tea (250ml): 25-35mg
- Energy drink (250ml can): 80mg
- Traditional gourd of mate (full session, many refills): 150-300mg spread over an hour or more
Figures vary with leaf quantity, water temperature, steep time and cut. A strongly packed gourd brewed hot will extract more; a quick French-press cup will extract less.
Why mate's caffeine feels different
Ask anyone who's switched from coffee and they'll tell you the same thing: mate feels smoother. There are three reasons.
1. Theobromine. Yerba mate contains theobromine, the gentle stimulant found in dark chocolate. It works alongside caffeine to deliver a calmer, longer-lasting lift.
2. Gradual intake. Traditional mate is sipped over 30-60 minutes through many small refills, not downed in five minutes like an espresso. Your caffeine arrives on a slope, not a spike, which is why the crash never quite comes.
3. Polyphenols and nutrients. Mate is rich in antioxidants and contains B vitamins, magnesium and potassium, which may moderate how the caffeine lands.
How much is too much?
UK guidance suggests healthy adults keep caffeine under about 400mg per day. That's roughly four cups of coffee, or a generous day of mate drinking. A morning gourd session (150-300mg across refills) sits comfortably within it. If you're pregnant, the NHS advises staying under 200mg per day, so check with a professional about whether mate fits your routine.
Does brewing method change the caffeine?
Yes, meaningfully:
- Traditional gourd and bombilla: highest total intake, spread gradually across refills. The same leaves release caffeine over 10-15 pours.
- French press (1 tbsp, 4-5 min steep): a single moderate dose, similar to a weak coffee.
- Cold brew / tereré: gentler extraction, lighter caffeine, very refreshing.
- Hotter water = more caffeine (and more bitterness). Stick to 70-80°C for the best balance.
Can I drink yerba mate every day?
Millions of South Americans do, often from morning to mid-afternoon. As with any caffeine, ease off in the late afternoon if it affects your sleep, and listen to your body. More on this in our yerba mate FAQs.
The bottom line
Yerba mate gives you slightly less caffeine than coffee per cup, delivered more gradually and paired with theobromine for a smoother ride. If you like coffee's energy but not its jitters and crashes, mate is the closest thing to an upgrade. See our full coffee vs mate comparison, or start with the beginner's guide.
