Barbacuá is a traditional wood-fire drying method that gives the drink its unmistakable smoky character. It is one of the oldest and most distinctive techniques used to process yerba mate. The term barbacuá refers specifically to the drying system, not to a flavor additive or a brand. Barbacuá yerba mate is yerba mate that has been dried using indirect heat and smoke from a wood fire. Unlike modern hot-air or industrial drying methods, barbacuá uses a slow, traditional process that deeply influences the taste, aroma and color of the final product. This technique has been used in South America for centuries and remains especially valued by traditionalists and experienced mate drinkers. |

Barbacuá comes from indigenous and rural South American practices. It describes a drying structure where yerba mate leaves are placed on elevated platforms while heat and smoke from a wood fire rise naturally from below.
Rather than rapidly removing moisture, barbacuá drying allows the leaves to transform gradually, absorbing smoky aromas and developing a deeper, more intense flavor.
How Barbacua is made?
Barbacua yerba mate goes through several essential processing stages. Barbacuá affects the most important one: drying.
- Harvesting
Leaves and small stems of Ilex paraguariensis are harvested, usually once or twice per year.
- Sapecado (Heat Shock)
The fresh leaves are briefly exposed to high heat to stop enzymatic oxidation. This step preserves color and prevents fermentation.
- Barbacuá Drying (Wood-Fire Method)
This is the defining stage: leaves are placed on raised wooden or metal platforms and a wood fire burns below or at a distance. Heat and smoke rise slowly through the leaves. Drying can take 12–24 hours or longer. This slow, smoky process creates barbacuá’s intense aromatic character.
- Aging
After drying, yerba mate is aged for 6 months to 2 years, allowing bitterness to soften and flavors to stabilize.
- Grinding and Blending
Finally, the leaves are ground and blended into the finished product.
Flavor and aroma profile
Flavor notes: smoky, earthy, woody, strong bitterness, long-lasting finish
Aroma: wood fire, campfire, toasted, rustic notes
Because of this bold profile, barbacuá is often considered an acquired taste.
Some producers offer “barbacuá suave”, which uses controlled or reduced smoke to create a milder version while preserving traditional character.
Is Barbacuá safe?
The research conducted by the National Institute of Yerba Mate (INYM) comparing barbacuá, belt, and rotary drying systems found that:
- Barbacuá preserved the highest total polyphenol content than belt, and rotary drying
- Microbiological safety was similar across all drying methods
- Barbacuá produced more intense color characteristics
Barbacuá yerba mate has been consumed for centuries, but modern health research highlights a few considerations:
Alternate between smoked and unsmoked yerba mate
Avoid drinking mate at extremely high temperatures
Choose brands that mention controlled or indirect smoking
Barbacuá yerba mate represents heritage, craftsmanship, and identity. In a world increasingly driven by efficiency and standardization, barbacuá stands as a reminder that processing methods shape not only flavor, but culture itself. For many mate enthusiasts, barbacuá isn’t just a style of yerba mate—it’s the most authentic expression of it.
