Brew loose leaf yerba mate by filling a gourd two-thirds full with leaves, adding cool water first, then hot—not boiling—water around 150°F–170°F.
Learning how to brew loose leaf yerba mate comes down to one idea: keep the leaves moist but never scorched. The traditional method uses a gourd and bombilla and rewards patience with a smooth, earthy brew you can refill all afternoon. You don’t need special equipment, though—a French press works nearly as well when you’re starting out.
The Traditional Gourd and Bombilla Method
The classic way to brew loose leaf yerba mate delivers the most authentic flavor and the fullest use of the leaves. It takes a few tries to get the rhythm, but the steps are simple once you see them.
Fill the gourd. Pour loose leaf yerba mate into your gourd until it’s about 2/3 to 3/4 full. That’s the standard fill level—less leaves makes a weak brew, and more leaves leaves no room for water.
Tilt and wet. Tilt the gourd so the leaves form a slope, with one side higher than the other. Pour cool or lukewarm water slowly onto the lower side so the leaves bloom and moisten before any hot water touches them. This first wetting step protects the flavor.
Add hot water. The water should be hot but not boiling—roughly 150°F–170°F. Boiling water burns the leaves and turns the brew bitter, so let a kettle rest a minute after it clicks off.
Insert the bombilla. Place the metal straw into the wet, lower side of the leaves. Keeping it there reduces clogging and leaves the dry side intact for refills.
Sip, refill, repeat. Traditional mate is refilled multiple times. Sip the wet side down, add more hot water, and keep going until the flavor fades. That’s the whole ritual—and sharing the gourd is part of the tradition too.
Brewing Without a Gourd: French Press Method
No gourd or bombilla? A French press makes a clean, full-bodied cup with almost no fuss. It’s the easiest way to brew loose leaf yerba mate when you’re traveling or just getting started.
Use about 1 tablespoon of loose leaf per 8 ounces of water. Heat the water to 150°F–170°F, pour it over the leaves, and steep for 4–5 minutes. Press the plunger down slowly and pour. The result is smoother than a gourd brew because the leaves never crowd together, and cleanup takes seconds.
If you want a cold option, try tereré-style cold brew: mix yerba mate with water at a 1:8 ratio, refrigerate for 12–24 hours, then strain. It’s refreshing, lower in bitterness, and perfect for warm weather.
| Method | Ratio & Steep Time | Best For |
|---|---|---|
| Traditional gourd | 2/3–3/4 full gourd; refill as you sip | Authentic flavor, long sessions |
| French press | 1 tbsp per 8 oz; steep 4–5 min | Quick single cups, no special gear |
| Cold brew / tereré | 1:8 yerba-to-water; chill 12–24 hrs | Refreshing iced drinks |
How Much Caffeine and What Are the Risks?
Yerba mate contains caffeine, so it can cause insomnia, jitters, an upset stomach, or a fast heartbeat if you overdo it. Most adults handle a daily cup fine—the Mayo Clinic notes regular drinking isn’t linked to health problems for most people, though very large long-term intake has been associated with higher cancer risk in some studies.
Studies that raised concerns involved roughly 1 to 2 liters per day over long periods. If you’re pregnant, sensitive to caffeine, or have heart issues, treat yerba mate like any caffeinated drink—start small and see how your body responds.
Choosing Quality Loose Leaf Yerba Mate
The brewing method matters, but the leaves matter more. Look for loose leaf yerba mate with visible stems and a fresh, grassy smell—that’s a sign of proper aging. Smoked or unsmoked varieties change the flavor profile noticeably, so try both to find your preference.

FAQs
Can I reuse the same loose leaf yerba mate for multiple refills?
Yes. Traditional brewing is built around refilling the gourd with hot water as you sip. The flavor gradually weakens, but most people get several refills before the leaves are spent—often 6 to 10 rounds depending on the quality of the leaves.
What happens if the water is too hot?
Water that’s boiling or near-boiling burns the leaves, which releases bitter compounds and ruins the smooth, grassy flavor yerba mate is known for. Aim for 150°F–170°F, or let boiled water sit for a few minutes before pouring.
Does yerba mate keep you awake like coffee?
Yerba mate contains caffeine, so it can keep you awake, especially in the evening. The effect is similar to coffee for most people, though some find it smoother and less jittery. If you’re caffeine-sensitive, limit intake to mornings.
