Traditional yerba mate is brewed by filling a gourd two-thirds full, tilting it, and pouring 158–176°F water over one side.
For the full breakdown, see our best Yerba Maté Tea guide.
Brewing yerba mate traditionally takes about five minutes and delivers a smooth, earthy drink you can refill all afternoon. The ritual matters — the temperature, the tilt, and the dry side of leaves all shape the flavor. Whether you want the authentic gourd-and-bombilla experience or a quick French press version, how to brew yerba mate tea comes down to a few details that are easy to get right once you know them.
The Traditional Gourd Method
Argentina’s official tourism guide breaks the traditional method into a clear sequence centered on one idea: keep some yerba dry so the gourd can be refilled again and again.
- Fill the gourd: pour loose yerba about 2/3 to 3/4 full.
- Shake it: cover the mouth with your palm, flip the gourd over, and shake gently so the fine particles settle at the top.
- Tilt to 45°: return the gourd upright and tilt it so the yerba forms a slope, leaving a pocket of empty space inside.
- Insert the bombilla: place the filter end into the lower side of the mound, angled along the gourd’s wall. Leave it there — stir it and the filter clogs.
- Moisten with cool water: pour a small amount of cool or room-temperature water onto the dry side to “bloom” the leaves. Wait a couple of minutes so they absorb it and swell.
- Add hot water: pour hot water at 70–80°C (158–176°F) slowly into the same side, keeping the upper slope dry.
- Sip and refill: drink through the bombilla, then add more hot water to the wet spot — never stir, never pour over the dry side.
That final step is what makes mate a session drink. A single gourd can take five or six refills before the flavor thins, which is why the dry-side rule matters so much. Once the whole mound is wet, the leaves are spent and the gourd is done.
What Water Temperature Actually Works
The one mistake that ruins mate more than any other is boiling water. Multiple guides converge on 158–176°F (70–80°C) as the sweet spot — hot enough to extract flavor, cool enough to avoid scorching the leaves and turning the brew bitter. The Buenos Aires tourist board’s guide recommends water around 70–80°C for a traditional gourd. While boiling water sits at 212°F, letting a kettle rest for a few minutes after it clicks off usually drops the temperature into the right range. If you own a variable-temperature kettle, set it to 175°F and skip the guesswork. For bagged mate or French press brewing, one source lands on roughly 170°F, with a steep of about five minutes. The temperature rule holds across every method — never boiling, always below the scorch point.
Quick Brewing in a Mug or French Press
Not everyone owns a gourd and bombilla, and that’s fine. Loose yerba works beautifully in a French press if you follow the same logic: bloom with cool water first, then steep hot.
- Mug and strainer: add 1–2 tablespoons of loose yerba, moisten with cool water, wait two minutes, add 170°F water, steep five minutes, then strain.
- French press: use the same ratio, push the plunger down less aggressively than you would for coffee so fine particles stay out of your cup.
- Tea bags: moisten the bag with cool water first, then steep at 170°F for five minutes. Simple, consistent, and nearly impossible to get wrong.
The cool-water bloom step matters even in a mug for the same reason it matters in a gourd. Yerba leaves release their flavor more evenly when they rehydrate gradually, instead of hitting hot water while still dry. Skipping it produces a thinner, flatter cup. The mate drink tradition spans centuries across South America, typically shared among friends with one gourd and one bombilla passed around in a circle.
Common Mistakes and Safety Notes
Even experienced drinkers fumble these. Boiling water is the biggest offender — it scorches the leaves and produces a harsh, bitter brew. Stirring after the bombilla is in place clogs the filter with fine powder. Wetting the entire mound kills the refill structure, leaving one weak infusion instead of a session. Skipping the cool-water bloom rushes the extraction and loses depth.
On safety, mate carries the same caveat as any caffeinated botanical: moderation matters. Pregnant women and people sensitive to caffeine should treat it like coffee — a genuinely strong source of stimulant, with comparable caution.

FAQs
How long does a gourd of yerba mate last with refills?
A properly prepared gourd typically lasts five to six refills before the flavor noticeably thins. The dry side of leaves fuels each infusion, which is why preserving it matters. Once the entire mound is wet, the leaves are exhausted and you need fresh yerba.
Can I use boiling water for yerba mate?
No. Boiling water scorches the leaves and produces a bitter, harsh brew. The widely recommended range is 158–176°F (70–80°C). If you don’t have a variable-temperature kettle, let water sit off the boil for two to three minutes before pouring.
What does the cool-water bloom step do?
The cool-water step rehydrates the leaves gradually so they release flavor evenly when hot water hits them. Skipping it leaves dry leaves that steep unevenly — the result is a thinner, flatter cup with less of mate’s characteristic smoothness.
