How to prepare mate: the gourd method and easier shortcuts

Step-by-step mate with a gourd and bombilla, why your water must not boil, how to cure a new gourd, plus French press and teabag methods that need no gear.

Published:

Mate is easy to make and easy to make badly. Almost every bad first mate comes down to two mistakes: boiling water and stirring the straw. Get those two right and the rest is detail.

This guide covers the traditional gourd method first, then two shortcuts that need no special equipment.

What you need

  • A gourd (mate) — natural calabash, wood, glass, ceramic or stainless steel.
  • A bombilla — the metal straw with a filter at the bottom. This is the non-negotiable piece; there is no substitute.
  • Yerba mate — start with a con palo blend. See best yerba for beginners.
  • A thermos, eventually. Not needed for the first cup, essential once you are hooked.

Gourds and bombillas are usually sold together as a set. The Irish yerba specialists carry them alongside the yerba, and there is a reasonable range of mate gourd and bombilla sets on Amazon.ie if you want it delivered fast.

Which gourd to buy first? A calabash gourd gives the most traditional flavour but needs curing and care. Glass or stainless steel needs no curing, will not go mouldy if you forget it overnight, and is the sensible first purchase — get the calabash once you know you are staying with it.

Curing a new gourd

Skip this entirely for glass, ceramic or steel. For natural calabash or wood:

  1. Fill the gourd with used yerba (from someone else’s mate, or brew a batch just for this) and top it up with warm — not boiling — water.
  2. Leave it to stand for about 24 hours.
  3. Tip it out and scrape the soft inner pulp off the walls with a spoon.
  4. Rinse and repeat once or twice, until the water comes out clean.
  5. Let it dry completely, mouth down, somewhere airy.

Curing seals the inside and seasons it. After that, the rule for the rest of the gourd’s life is simple: rinse after use, dry it mouth-down, never leave wet yerba sitting in it overnight. Wet yerba left in a calabash for two days grows mould, and that is how most gourds die.

The gourd method, step by step

1. Heat the water to 70–80°C. Not boiling. If your kettle has a temperature setting, use it. Otherwise boil and wait five minutes, or add a splash of cold water to the thermos.

2. Fill the gourd about two-thirds to three-quarters with yerba. More than you think. It should look overfull compared with a teabag.

3. Shake out the dust. Cover the mouth with your palm, turn the gourd upside down, shake it gently, then bring it back upright at an angle. This sends the finest powder to the top, away from where the straw will sit — which is exactly what stops the bombilla clogging.

4. Tilt the yerba to one side. Hold the gourd at about 45° so the yerba forms a slope, leaving a hollow against the near wall. This slope is the whole trick: one side stays dry in reserve while the other side brews.

5. Wet it with cool water first. Pour a little cool or lukewarm water into the hollow and let it soak in for a minute. This protects the leaf from thermal shock and preserves the flavour for far more refills. Do not skip it.

6. Insert the bombilla into the wet hollow — filter end down, pressed against the base — and then do not move it again. Not to stir, not to check, not once. Every movement drags fine powder into the filter and blocks it.

7. Pour the hot water into the same hollow, never over the dry slope. Fill just to the level of the yerba.

8. Drink it all. The gurgle at the end is the signal it is empty, not a faux pas.

9. Refill in the same spot and keep going. Rotate the wet patch slowly across the dry yerba as each area washes out. Fifteen to twenty refills is normal.

When the brew turns pale and flat, the mate is lavado — washed out. Tip it, rinse, start again.

If you are sharing

One person, the cebador, keeps the thermos and pours for everyone. Each person drinks the entire gourd and hands it straight back to the cebador, who refills and passes it on. Do not pass it sideways to the next person yourself, do not stir it, and only say “gracias” when you have had enough for good — it means “I am out”.

Shortcut 1: French press

The best method if you do not own a gourd. It is not a substitute for the ritual, but the flavour is close.

  1. Add about one heaped tablespoon of yerba per cup to the press.
  2. Pour in water at 70–80°C.
  3. Steep three to five minutes.
  4. Press slowly and pour.

The plunger’s mesh handles the coarse leaf well; very fine Uruguayan yerba will slip through, so use a con palo blend here. You can usually get a second, weaker brew out of the same grounds.

Shortcut 2: mate cocido (teabags)

Yerba sold in teabags, brewed exactly like tea: bag in a mug, water at 70–80°C, three to five minutes. It is what Argentinian kids drink at breakfast, commonly with milk and sugar, and it is completely legitimate — not a tourist version.

It is the cheapest possible way to find out whether you like the flavour before buying anything. Note that Irish health-food shops sometimes sell mate teabags that are not Argentinian brands and taste noticeably milder.

Tereré: the cold version

Same gourd, same bombilla, but with ice-cold water or citrus juice instead of hot water, often with mint or lemon added to the thermos. Paraguayan in origin and the standard way mate is drunk in summer heat. On the two warm weeks Ireland gets, it is genuinely excellent.

Common mistakes

Mistake What happens Fix
Boiling water Harsh, burnt, bitter; washes out in five refills 70–80°C
Skipping the cool-water step Flavour dies quickly Wet the leaf first, wait a minute
Stirring the bombilla Instant clog Place it once, leave it
Not enough yerba Weak, washes out immediately Two-thirds to three-quarters full
Pouring over the dry side Whole gourd washes out at once Always pour into the same hollow
Leaving wet yerba in overnight Mould in a calabash gourd Empty, rinse, dry mouth-down

Frequently asked questions

What water temperature should I use?
Roughly 70-80C — hot but clearly off the boil. If your kettle has no temperature setting, boil it and wait about five minutes, or add a splash of cold water. Boiling water scalds the leaf, makes the brew harsh and burns through the yerba in a few refills.
Why does my bombilla keep clogging?
Almost always one of three things: the yerba was never wetted with cool water first, the bombilla was moved or stirred after being placed, or you are using a very fine sin-palo or Uruguayan yerba with a straw whose filter is too coarse. Wet the leaf first, place the straw once, and start with a con-palo blend.
Do I need to cure a new gourd?
Only if it is a natural calabash gourd or wood. Fill it with used yerba and warm water, leave it a day, scrape out the soft inner pulp, rinse and repeat once or twice until the water runs clean. Glass, ceramic and stainless steel gourds need no curing at all and are the low-maintenance option.
How many refills does one filling give?
With good yerba and correct water temperature, a gourd typically lasts fifteen to twenty refills before the flavour washes out, which is most of a large thermos. When it tastes flat and pale, the mate is lavado — washed out — and it is time for fresh yerba.
Can I make mate without a gourd?
Yes. A French press works well and is the best gear-free approximation. Yerba in teabags, sold as mate cocido, brews exactly like tea. Neither is the same experience as a gourd, but both are a fair way to find out whether you like the flavour before spending anything.
