Comparing Smoked and Unsmoked Yerba Mate


Yerba mate, a traditional South American brew, stands at the crossroads of a longstanding debate: smoked versus unsmoked.

This division among Mate enthusiasts isn't just about preference; it's a conversation entwined with health concerns, tradition, and the evolution of mate consumption from its indigenous roots to a global stage.

At the heart of this discussion are questions about whether the traditional smoking process contributes to health risks, specifically cancer, and whether unsmoked varieties offer a safer alternative without sacrificing the beverage's revered qualities. 

This article presents insights into the production processes, health studies, and cultural significance of Yerba Mate.

The History and Evolution of Yerba Mate

Origins and Cultural Significance

Yerba mate's journey begins with the Guaraní tribes of South America, for whom the beverage was not just a drink but a ritual offering to the gods. Traditionally, the leaves were dried over a fire, imparting a distinct smoky flavor to the brew. This method, preserved through the barbacuá system, has been passed down through generations, underlining the drink's rich cultural tapestry.

Global Popularity and the Rise of Unsmoked Mate

As Yerba Mate ventured beyond its traditional borders, reaching global markets, its health implications underwent examination. Reports linking Mate's consumption to cancer, purportedly due to the smoking process, sparked controversy and fear. Sensationalist media headlines exacerbated these concerns, leading to a demand for unsmoked varieties. These newer versions are dried using methods that avoid direct smoke exposure, aiming to reduce the presence of polycyclic aromatic hydrocarbons (PAHs), compounds associated with cancer risk.

The shift towards unsmoked Yerba Mate reflects a broader dialogue about health, tradition, and the adaptability of cultural practices in the face of scientific inquiry. As we delve deeper into the production processes of both smoked and unsmoked Yerba Mate, we must remember these historical and cultural contexts, recognizing the balance between preserving tradition and embracing innovation for health's sake.

Production Processes

Understanding the differences between smoked and unsmoked Yerba Mate begins at the source: the production process. Each step is crucial in defining the final product's flavor, aroma, and health implications from harvesting to drying.

Smoked Yerba Mate

The traditional method of producing Yerba Mate involves two critical steps: sapeco and secado.

Sapeco is the initial drying phase, where freshly harvested Yerba Mate leaves are exposed to high heat and flames for about 30 seconds. This quick exposure to fire is not just about drying; it's a pivotal moment where the leaves develop their smoky flavor.

Historically, this was done by hand, with workers rotating branches over an open fire. Today, this process has been modernized, but the essence remains the same, with leaves passing through the flames of a furnace before entering a rotary cylinder.

Secado follows the sapeco, serving as the final drying stage. Here, the temperature is lower, ranging from 76.67-110°C, and the drying period extends over 10-12 hours or more.

The traditional method, barbacuá, involves drying the leaves in a chamber filled with smoke from burning wood. This prolonged exposure further infuses the Mate with its smoky essence, distinguishing the smoked Yerba Mate from its unsmoked counterpart.

Unsmoked Yerba Mate

In contrast, unsmoked Yerba Mate bypasses the traditional smoke-infused secado process in favor of air-drying techniques. These methods involve drying the leaves with warm or hot air from sources like boilers, gas flames, or electricity, avoiding direct contact with smoke.

This approach aims to minimize the presence of PAHs in the final product, addressing health concerns associated with smoked varieties.

The taste and aroma of unsmoked Yerba Mate differ significantly from the smoked version. Consumers often report a cleaner, fresher taste without the smoky flavor characteristic of the traditional Mate. This difference makes unsmoked Yerba Mate appealing to those seeking the herb's health benefits without the smoky undertones.


Health Concerns and Studies

The debate over smoked versus unsmoked Yerba Mate is deeply rooted in health concerns, specifically the risk of cancer. Central to this discussion are the studies examining the relationship between Mate consumption and cancer incidence, along with the role of PAHs.

Smoked Yerba Mate and Cancer Risks

Research has drawn connections between traditional (smoked) Yerba Mate consumption and an increased risk of certain cancers, notably esophageal cancer [1]. However, these studies often face criticism for their methodology, including reliance on self-reported consumption habits and failure to isolate Yerba Mate as the sole variable, given that subjects frequently also consumed tobacco and alcohol.

Despite these limitations, the presence of PAHs in smoked Yerba Mate is well-documented. PAHs, particularly benzo[a]pyrene, are known carcinogens formed during the combustion of organic matter, including wood. Their presence in smoked Yerba Mate raises valid concerns, given the established health risks associated with PAH exposure.

Unsmoked Yerba Mate and PAH Presence

While unsmoked Yerba Mate's processing method minimizes direct smoke exposure, studies indicate that it is not entirely free of PAHs. It is because the initial sapeco step involves brief exposure to high heat and flames, which can introduce PAHs to the leaves.

Furthermore, environmental factors, such as soil and air contamination, can contribute to PAH's presence in Yerba Mate, regardless of the drying method.

However, the levels of PAHs in unsmoked Yerba Mate are generally lower than those found in smoked varieties [2]. This reduction in PAH content is a primary argument for those advocating for unsmoked Mate as a healthier alternative. Yet, the debate still needs to be settled, with ongoing research to fully understand the implications of PAH exposure from Yerba Mate consumption.

Consumer Choices and Safety

Consumers must navigate a landscape filled with traditional practices, modern health concerns, and the quest for the authentic Yerba Mate experience in the face of the smoked vs. unsmoked Yerba Mate debate. Making informed decisions requires understanding the nuances behind Mate production and the potential health implications of consuming different varieties.

Making Informed Decision

Consumers looking to enjoy Yerba Mate while minimizing health risks can consider several factors:

Research and Awareness: Keeping abreast of the latest Yerba Mate and PAH levels can help consumers make informed choices. You must understand the production process and how it impacts the final product's PAH content.

Quality and Source: Opting for Yerba Mate from reputable sources that prioritize sustainable and health-conscious production methods can make a difference. Organic varieties often imply stricter standards for production and processing, potentially leading to lower PAH levels.

Tips for Choosing High-Quality Yerba Mate

When selecting Yerba Mate, consider the following tips to ensure you're getting a high-quality product:

  • Look for Transparency: Brands that provide detailed information about their production processes, including whether their Mate is smoked or unsmoked, offer consumers greater transparency and peace of mind.
  • Certifications: Organic, non-GMO, and Fair Trade can indicate higher production standards and ethical sourcing.

Taste Preferences: Ultimately, the choice between smoked and unsmoked Yerba Mate may come down to personal taste preferences. Sampling different varieties can help you find the balance between flavor and health considerations that work best for you.

Comparing Smoked and Unsmoked Yerba Mate


The ongoing debate between smoked and unsmoked Yerba Mate encapsulates a broader conversation about tradition, health, and the modern adaptation of ancient practices. While current research provides some guidance on the potential health implications of PAH exposure through Yerba Mate consumption, many questions remain unanswered.
