info The classic Argentine mate: yerba leaves in a gourd, water at 70–80°C, sipped through a bombilla and refilled many times.

Execution Methodology & Culinary Technique

1. 1

   Heat the Water — Never Boiling

   5 Mins Water 70–80°C (158–176°F)

   Heat the water in a kettle until it reaches 70–80°C (158–176°F). If it boils, leave the lid off for a minute or two until it cools to the right range — water that is too hot burns the leaves and the mate turns bitter and flat.

   No thermometer? Take the kettle off the boil and count to 60 — that is usually close enough, and you can test a drop on the inside of your wrist.

   Done when: Steaming water that does not bubble; a thermometer reads 70–80°C.

2. 2

   Fill and Shake the Gourd

   2 Mins Room temperature, ~20°C (68°F)

   Fill the calabash gourd about two-thirds full with yerba mate, cover the opening with your palm, turn it upside down and shake it firmly 4–5 times. This brings the fine powder to the top. Turn it back over and tip the leaves to one side, leaving a hollow pocket on the other side.

   A cured gourd is best — a new gourd should be cured with hot water and used yerba overnight first, or the drink tastes of raw gourd.

   Done when: The leaves sit in a slope, with a clear hollow on one side.

3. 3

   Swell the Leaves with Cold Water

   2 Mins Room temperature, ~20°C (68°F)

   Pour the cold water into the hollow and let it sit for about a minute so the leaves swell and settle. This protects the leaves from the hot water and keeps the first sips smooth instead of dusty.

   Do not skip the cold water — pouring hot water straight onto dry leaves is what clogs the bombilla.

   Done when: The leaves darken and swell; the hollow holds a little pool of water.

4. 4

   Place the Bombilla and Add Hot Water

   3 Mins Water 70–80°C (158–176°F)

   Slide the bombilla into the hollow, filter end down, and hold it still — do not stir or move it again, or the leaves will block the filter. Pour the hot water slowly into the hollow until the gourd is nearly full, and wait a minute for the leaves to drink it in.

   Once the bombilla is in, it stays put. Moving it stirs the leaves into the filter and every sip after that will be blocked.

   Done when: The water level sits just below the rim and the leaves are evenly wet.

5. 5

   Sip, Refill and Share

   3 Mins Serve at 70–80°C (158–176°F)

   Sip through the bombilla straight away — one serving is one gourd, about 250 g. When the gourd runs dry, refill it with more hot water from the thermos; a single fill of yerba gives many refills. In Argentina the gourd is passed from hand to hand, each person drinking it all before it is refilled and passed on.

   The first refill is the strongest; the flavour softens with each pour, and the gourd is done when the mate tastes of plain warm water.

   Done when: A smooth, herbal sip with no leaves in the straw; the gourd refills cleanly.

Who Should Eat It

Who Should Eat

• General adultsA fine daily drink for most adults — one or two gourds a day, unsweetened, is the usual habit.
• ChildrenNot recommended for young children because of the caffeine; older children can have a weak, small cup if the family wishes.
• ElderlyA light, warm drink that is easy to sip; keep the caffeine modest and the water at the right temperature.
• Pregnant womenMate contains caffeine, so keep it moderate and talk to your clinician about how much caffeine suits you in pregnancy.
• Breastfeeding womenCaffeine passes into breast milk in small amounts, so keep mate moderate and watch the baby's sleep. Ask your clinician if unsure.
• AthletesA low-calorie, caffeine-containing drink that fits well before training; it does not replace water for hydration.
• Weight gainAlmost no calories, so it will not help with weight gain on its own — pair it with pastries or a snack.
• Weight lossAbout 5 kcal a gourd unsweetened, so it is an easy swap for sugary drinks — just skip the sugar.

Health Conditions — Adjust or Avoid

Conditions

• DiabetesUnsweetened mate has no sugar and about 0.9 g of carbohydrate a gourd, so it fits most meal plans. Ask your clinician about portion size.
• High blood pressureSodium is negligible and the drink is unsweetened; caffeine can raise blood pressure briefly in some people, so keep it moderate. Ask your clinician about portion size.
• Kidney diseaseVery low in minerals and protein; a moderate amount is usually fine, but ask your clinician first.
• GoutLow in purines, so generally fine in a normal amount. Ask your clinician about frequency.
• Stomach issuesThe warm, herbal drink is usually gentle on the stomach, but strong mate on an empty stomach can cause discomfort — drink it with food if you are sensitive. Ask your clinician if symptoms persist.
• Cardiovascular diseaseCaffeine can quicken the heart rate in some people, so keep mate moderate and avoid very strong brews. Ask your clinician about portion size.
• Fatty liverNo sugar and no fat, so it adds nothing to the liver's load when drunk unsweetened. Ask your clinician about portion size.
• Food allergiesContains no common allergen — just yerba leaves and water. Ask your clinician if you have any rare plant allergy.
• Special therapeutic dietsIf you follow a prescribed low-caffeine diet, mate counts towards your caffeine limit; check with your clinician before drinking it regularly.

If you have a medical condition, consult your doctor before changing your diet.

kitchen Storage & Use

Storage & Use

How to store

Mate is brewed fresh each time and drunk at once; store the dry yerba in an airtight container away from light.

In the fridge

Brewed mate does not keep — make it fresh; it turns flat and bitter within an hour.

In the freezer

Do not freeze brewed mate.

How to reheat

Do not reheat a brewed gourd — brew a fresh one with hot water at 70–80°C (158–176°F).

Freezing recommended

No — the dry leaves keep for months in a sealed jar; the drink itself is made fresh.

Signs it has spoiled

Stale, dusty smell from old yerba, or a gourd that smells sour or mouldy — clean and re-cure the gourd.
