Does Yerba Mate Have Caffeine?

Yerba Mate does contain caffeine. It is one of the naturally occurring compounds in the Yerba Mate plant. On average, an 8-ounce serving of Yerba Mate contains approximately 30-50 milligrams of caffeine, although the caffeine content may vary.

However, this amount can vary depending on factors such as the type of Yerba Mate leaves used and how they are prepared.

How Much Caffeine Does Yerba Mate Have?

How Much Caffeine Does Yerba Mate Have

The caffeine content in Yerba Mate can vary depending on factors such as the type of leaves used and the brewing method. A 150 mL cup of Yerba Mate tea contains approximately 80 mg of caffeine, similar to the caffeine content in a standard coffee cup. [1]

On the other hand, Matcha tends to have a higher caffeine content. An 8-ounce serving of matcha typically contains around 70 milligrams of caffeine.

However, some varieties of Yerba Mate may have higher caffeine concentrations, reaching levels similar to that of Coffee.

Despite its caffeine content, many people find that Yerba Mate provides a smoother and more sustained energy boost than Coffee, often without the jitters or crashes associated with high caffeine intake.

What are the Factors Affecting the Caffeine Content of Yerba Mate Tea?

Factors that can affect the caffeine content of Yerba Mate include:

Yerba Mate Type

  • Varieties/Cultiva: Different strains of the Yerba Mate plant may contain varying amounts of caffeine. For example, some varieties are bred to produce leaves with a higher concentration of caffeine than natural Yerba mate.
  • Leaf maturity: Young leaves tend to contain more caffeine than older leaves. At the same time, the time the leaves are harvested can also affect the overall caffeine content in Yerba Mate.
  • Growing conditions: Environmental factors such as soil, climate, altitude, and sunlight can affect the concentration of caffeine in Yerba Mate leaves.

Preparation Method

Preparation Method of Caffeine Content
  • Temperature of brewing: Using water at a higher temperature than usual helps extract caffeine from the leaves more effectively. However, excessively high temperatures can also lead to a decrease in desired compounds and alter the flavor of the tea.
  • Steeping time: Steeping Yerba Mate for a sufficient amount of time or longer than usual can result in higher caffeine extraction. However, it's important to note that steeping for too long may lead to a bitter taste.
  • Ground leaves vs. whole leaves: Grinding or shredding the leaves before brewing can increase the surface area in contact with water, potentially enhancing caffeine extraction. Conversely, using whole leaves may slow the release of caffeine during the steeping process.

Serving Size

Serving Size of Yerba Mate
  • Volume of Tea: Larger servings of Yerba Mate Tea naturally contain more caffeine than smaller servings. Adjusting the amount of tea leaves used per serving can directly influence caffeine intake.
  • Strength of Brew: The concentration of Yerba Mate Tea can be adjusted by varying the ratio of tea leaves to water. A stronger brew will contain more caffeine per unit volume than a weaker one.
  • Dilution: Adding water or other liquids to the prepared tea can dilute its caffeine content. Conversely, consuming concentrated forms of Yerba Mate Tea, such as espresso-style shots or concentrates, will increase caffeine intake per serving.

Does Cold Brew Yerba Mate Have More Caffeine?

Cold brew Yerba Mate may have a slightly higher caffeine content than hot-brewed Yerba Mate due to the longer steeping time, but the difference is minimal.

The extended steeping period in cold brewing compensates for the lower temperature, resulting in comparable caffeine levels.

However, variations can still occur based on factors like the type of leaves used and brewing technique. While cold brew Yerba Mate offers a smoother flavor, its caffeine content isn't significantly different from hot-brewed versions.

Key Benefits of Yerba Mate Tea?

Here are some health benefits of yerba mate tea supported by specific evidence:

  • Rich in Antioxidants: Yerba mate contains high levels of antioxidants, such as polyphenols and flavonoids, which help protect cells from oxidative stress. [1]

  • Dehydration: Caffeine is a diuretic, increasing urine production and can contribute to dehydration if not consumed alongside adequate fluids.
  • Pregnancy Concerns: High caffeine intake during pregnancy has been associated with an increased risk of miscarriage, low birth weight, and other complications. Pregnant individuals are often advised to limit caffeine intake, including that from Yerba Mate.
