Axis by axis
Short answer
Per serving, yerba mate carries more caffeine than a single espresso: CupCura lists 85 mg for an 8 oz infusion against 64 mg for a 30 ml shot. Per millilitre the order reverses, because espresso is several times more concentrated. The practical difference is how you drink them. A shot is one dose, finished in a minute. A gourd is refilled for an hour or more, so the total depends on how many fills you take.
The serving basis
The catalogue figure for mate is for one 8 oz (about 237 ml) infusion, and the record notes that a gourd is refilled. CupCura's recipe packs the gourd with 30 g of leaf and pours 237 g of water at 75°C (167°F), a ratio of 1:8. That works out at about 36 mg per 100 ml, against about 213 mg per 100 ml for the espresso. A shot is therefore not comparable with a cup, and each further pour from the same gourd adds caffeine on top of the first.
What published measurements say
Yerba mate. A 2025 review in the Journal of Food Science puts caffeine at 0.3% to 1.8% of dry leaf weight, depending on cultivar, region and processing, and gives 78 to 196 mg per 500 ml serving. Scaled to 500 ml, the catalogue's 85 mg per 237 ml is about 179 mg, near the top of that range. The same review says a litre or two a day may amount to roughly 100 to 300 mg, which sits awkwardly beside its own per-serving range and shows how loosely mate intake is documented. A 2024 lab study of three yerba mate samples, brewed at 70°C and 100°C, found 13.5 to 22.0 mg of caffeine per gram of dry matter in single infusions, with double-brewed leaf averaging lower (14.3 against 17.8 mg per gram on average). The paper's units are ambiguous (it does not make clear whether the dry matter is the leaf or the infusion solids), so read it as a direction, not a cup figure: reused leaf yields less.
Espresso. The USDA lists restaurant-prepared espresso at 212 mg per 100 g, which makes a 30 ml shot about 63 mg, in line with the catalogue. Real shots vary. A study of 120 coffees from Warsaw franchise shops found espresso averaging 198.6 mg per 100 ml (standard deviation 68.3), or about 60 mg per 30 ml with a spread of roughly 40 to 80 mg. Another analysis of 20 commercial espressos found a six-fold range, with one at 322 mg, and blamed mainly the amount of coffee used.
Against brewed coffee. Many people searching this comparison mean ordinary coffee. By simple arithmetic from the USDA's 40 mg per 100 g, an 8 oz cup of brewed coffee is about 95 mg, so one mate infusion at 85 mg sits just below it. The FDA gives 113 to 247 mg for a 12 fl oz cup of brewed coffee.
Which to pick
- Mate if you like a long, social, sipped drink and want the caffeine spread across an hour or two rather than taken at once. See the yerba mate guide and the Argentine and Uruguayan mate traditions.
- Espresso if you want a fixed, quick dose, or the base for a milk drink.
- Skip both late in the day if caffeine affects your sleep: the caffeine half-life guide covers timing.
- Ask a clinician first if you are pregnant, breastfeeding or take medication affected by caffeine. The NHS advises no more than 200 mg a day in pregnancy, and the pregnancy caffeine guide has more.
The FDA describes 400 mg a day as a level not generally linked to negative effects for most adults, and says sensitivity varies. A 500 ml gourd at 78 to 196 mg equals roughly one to three catalogue shots of 64 mg, so counting refills matters.
Honest limits
Mate has far less measurement behind it than coffee. Per-cup figures depend on how much leaf is used, how often it is refilled and the water temperature, and the sources opened here do not agree on one number. The espresso numbers come from retail coffees and a USDA entry, not from your machine and beans.
Questions
Is yerba mate coffee or tea?
Neither. It is an infusion of the dried leaves of Ilex paraguariensis, a holly native to South America. Tea comes from Camellia sinensis and coffee from coffee beans.
Can you drink yerba mate and coffee on the same day?
Yes, but the caffeine adds up, so count both toward your daily total. One infusion at 85 mg and one espresso at 64 mg is 149 mg at catalogue figures.
Is yerba mate healthier than coffee?
This page does not rank them. The measurable difference is the dose and how it is taken. If you have a medical condition or take medication, ask a clinician.
