Yerba mate is a traditional South American beverage made from the dried leaves and stems of the Ilex paraguariensis plant. For those managing their nutrition diet, knowing its caffeine content is important, but there's no single answer. The amount of caffeine can range from as low as 20 mg in a single tea bag to over 150 mg in a modern canned beverage. Several factors influence this wide range, giving drinkers the flexibility to control their intake.
Factors Affecting Yerba Mate's Caffeine Levels
Brewing Method
The way you prepare your yerba mate has the biggest impact on its caffeine level.
- Traditional Gourd and Bombilla: This method involves repeatedly refilling a gourd with hot water over a period of time. With a typical 50-gram loose-leaf portion, you can extract between 150 to 200 mg of caffeine gradually, comparable to a strong cup of coffee.
- French Press: Using a French press for a modern brew typically yields a lower concentration. A single tablespoon of loose leaf can result in about 50–60 mg of caffeine per serving, depending on the steep time.
- Tea Bags: This is the most convenient and lowest-caffeine option. An average tea bag contains around 20–40 mg of caffeine, similar to green tea.
- Cold Brew (Tereré): Cold water extracts caffeine more slowly than hot water, so a cold brew requires a longer steeping time (often overnight) to achieve a comparable caffeine level to a hot preparation.
Leaf-to-Water Ratio
Simply put, using more yerba mate leaves relative to the amount of water will increase the final caffeine concentration. This is particularly relevant with traditional gourd preparation, where the amount of herb used is often much higher than in a single tea bag.
Water Temperature and Steeping Time
Hotter water and longer steeping times extract more caffeine from the leaves. However, using boiling water can create a bitter taste. The ideal temperature is typically between 170–180°F (77–82°C). This gives you a smoother flavor while still effectively extracting the caffeine and other beneficial compounds.
Brand and Cut
Different brands and cuts of yerba mate also influence caffeine levels. Yerba mate with a higher leaf-to-stem ratio (despalada) will generally have more caffeine than brands containing more stems (con palo), as the caffeine is primarily concentrated in the leaves. Pre-packaged canned drinks offer standardized caffeine content, which is always listed on the label.
Yerba Mate Caffeine Comparison Table
| Beverage (Serving) | Estimated Caffeine Content | Notes |
|---|---|---|
| Yerba Mate (Traditional Gourd) | 150–200 mg (over multiple refills) | Caffeine is released gradually; total depends on the session length. |
| Yerba Mate (Canned, 15.5 fl oz) | 80–150 mg | Varies by brand and flavor; check the product label. |
| Yerba Mate (French Press, 8 oz) | 50–60 mg | Depends on the amount of leaf and steep time. |
| Yerba Mate (Tea Bag, 8 oz) | 20–40 mg | Lowest caffeine option; similar to green tea. |
| Coffee (Drip, 8 oz) | 95 mg | Typical average for brewed coffee. |
| Black Tea (8 oz) | 40–70 mg | Higher than green tea but less than most yerba mate brews. |
Yerba Mate's Unique Energy Profile
While yerba mate contains caffeine, its stimulating effect is often described as smoother and more balanced than coffee. This is due to its unique combination of methylxanthines, which includes caffeine, theobromine, and theophylline.
- Theobromine: Also found in chocolate, this compound is a milder, longer-acting stimulant that can relax blood vessels, potentially improving blood flow and reducing the intensity of caffeine's effects.
- Theophylline: This compound has a slight bronchodilating effect and works in synergy with the other stimulants.
- Smooth Energy Boost: For many drinkers, this combination results in sustained alertness and focus without the jitters, anxiety, or crash often associated with high doses of coffee.
Incorporating Yerba Mate Into a Balanced Nutrition Diet
Beyond its energy-boosting properties, yerba mate is rich in antioxidants, vitamins, and minerals. It can be a healthier alternative to energy drinks loaded with sugar and artificial additives, offering a clean source of energy. When incorporating it into your diet, mindful consumption is key:
- Monitor Your Intake: Keep track of your total caffeine intake from all sources, especially if you are sensitive to its effects.
- Listen to Your Body: Pay attention to how yerba mate affects you. Some people may be more sensitive to the stimulant effects than others.
- Mind the Temperature: While yerba mate is traditionally served hot, research has linked the long-term consumption of very hot beverages with an increased risk of certain cancers. Drinking it at a warm or cold temperature is a safer alternative.
- Hydration: Always accompany caffeinated beverages with plenty of water to stay hydrated throughout the day.

Conclusion
The caffeine content in a yerba mate drink is highly variable, ranging from a mild 20-40 mg in a tea bag to over 150 mg in a canned energy drink or a traditionally brewed session. Unlike the abrupt spike from coffee, yerba mate's unique combination of caffeine, theobromine, and other compounds provides a smoother, more sustained energy boost. By understanding how different factors like brewing method, brand, and preparation influence caffeine levels, you can confidently integrate yerba mate into your nutrition diet to achieve balanced energy and mental clarity without the unwanted jitters.
