What is Yerba Mate?
Yerba mate is the dried leaf of Ilex paraguariensis, an evergreen tree in the holly family. Native to southern Brazil, north eastern Argentina and Paraguay, it grows in the humid subtropical forests of the Paraná River Basin. Once dried and cut, yerba mate has a deep green colour, papery texture and a brisk, grassy flavour with a naturally bitter, drying finish.
Yerba mate has a long history of use among the Guarani people of South America and was later cultivated commercially by Jesuit missions from around 1670[1]. Traditionally, the dried leaves are packed into a gourd and infused with hot water, then drunk through a metal straw known as a bombilla. Water is typically added at around 65 to 80°C rather than boiling, and this style of preparation remains common across Argentina, Uruguay, Paraguay and southern Brazil[1].
At Austral Herbs, we supply certified organic yerba mate in several formats, including teabag cut, whole leaf, roasted, aged and powder. Each variant is ACO certified and processed in a HACCP certified facility. The different cuts and processing styles suit different applications, from loose leaf tea and teabags to beverage production and dry blending. If you’re comparing grades, our guide to tea leaf grading explains how cut size and processing can influence the final infusion.
Traditional Uses of Yerba Mate
Yerba mate has been consumed for centuries in South America, where it is traditionally prepared as a brewed leaf infusion and enjoyed as part of everyday social and cultural routines.
Traditional Wellness Use
Yerba mate is traditionally prepared by heating freshly harvested leaves, drying them and allowing them to mature before packing[1]. This processing helps shape the flavour and character of the finished drink.
In its native regions, yerba mate has historically been consumed as an everyday beverage rather than used for a specific health condition[1]. This differs from how herbalists use dried botanicals, where individual herbs may be selected as part of a broader formulation.
Antioxidant Properties
The leaf naturally carries a high polyphenol content, with chlorogenic acid reported as the dominant compound[1]. Research has investigated the antioxidant activity of yerba mate extracts in laboratory and animal work, though the evidence remains limited and mixed, and a concentrated extract is not the same thing as a brewed cup[1].
Naturally Occurring Caffeine Content
Yerba mate naturally contains caffeine, typically at around 1 to 2% of the dried leaf by weight, along with smaller amounts of the related compound theobromine[1].
Its natural caffeine content is one reason yerba mate is commonly used in teas and beverage formulations designed to contain caffeine. As with other caffeinated products, excessive intake may cause side effects such as stomach discomfort, difficulty sleeping or a faster heartbeat.
Some observational research has also linked very high, long-term consumption of yerba mate with an increased risk of certain cancers, although factors such as drinking temperature and other lifestyle influences may also play a role[2].

What Industries Can Yerba Mate Be Used In?
Yerba mate is a versatile botanical ingredient because it combines a distinctive green, herbaceous flavour with naturally occurring caffeine. This makes it suitable for both flavour-led and functional product development across a range of industries.
Tea
Tea blenders commonly use yerba mate as a naturally caffeinated base or supporting ingredient in loose-leaf and teabag blends. We explore this further in our guide to crafting teas with dried botanicals. Its robust, slightly bitter and astringent character can provide structure to blends containing lighter herbs, flowers or fruit ingredients. Coarser cuts are often suited to loose-leaf products, while finer cuts can work well in teabags. Roasted yerba mate can also provide a darker, more toasted flavour profile for different styles of tea.
Food Manufacturing
Yerba mate can also be incorporated into snack bars, baked goods, powdered mixes and other functional food products. Its distinctive herbaceous flavour can remain noticeable alongside ingredients such as cocoa, sweeteners and dairy, making it useful where the botanical itself is intended to contribute to the flavour profile. Powdered yerba mate is particularly practical for dry blending and applications where an even distribution throughout the finished product is required.
Creative
Dried yerba mate can also be used in non-food applications such as botanical displays, pressed plant work, styling and craft projects. Its dried leaf texture and natural green-brown appearance make it suitable where visible plant material is part of the finished look. Coarser leaf cuts are generally more practical for these uses than powder, as the leaf structure remains easier to see and handle.
Beverage Manufacturing
Yerba mate is widely used in energy drinks, functional beverages, ready-to-drink teas and cold brews because it naturally contains caffeine while also contributing its own distinctive herbaceous flavour. It can be brewed as the main botanical base or combined with ingredients such as citrus, fruit, ginger and other herbs to create more complex flavour profiles. Finer leaf cuts and powders are particularly useful in commercial beverage production because they provide greater surface area for extraction and can be incorporated efficiently into larger production runs.
Shop Our Yerba Mate Collection
Our yerba mate range includes several certified organic formats, each suited to different applications. The main differences are cut size and processing method, which affect how quickly the leaf extracts, how it handles in production and the flavour it brings to the finished product.
Yerba Mate TBC Organic
Yerba Mate TBC Organic is cut to approximately 1 to 2mm, making it a good choice for teabags, sachets and other applications where a smaller, consistent leaf size is important. The finer cut provides more surface area than coarse loose leaf, which can help the mate infuse more efficiently. It is best suited to tea companies, beverage manufacturers and other buyers who prioritise consistent extraction and easy portioning over the visual appearance of the whole leaf.

Yerba Mate Roasted Organic
Yerba Mate Roasted Organic is defined by its roasted flavour profile. Roasting reduces some of the fresh, grassy character associated with traditional mate and introduces deeper toasted, earthy and cocoa-like notes. Choose roasted yerba mate when you want the natural caffeine and character of mate without making a bright green or highly herbaceous flavour the focus. It works particularly well in richer tea blends, warming beverages and formulations paired with ingredients such as cocoa, vanilla or spices.
Shop Now
Yerba Mate Aged Organic
Yerba Mate Aged Organic is matured after drying, allowing its flavour to develop before packing. Compared with a fresher style of mate, aged leaf generally offers a smoother and more rounded flavour with less of the sharp green character. It is a useful choice for tea blenders and beverage developers who want yerba mate to remain recognisable while creating a more mellow finished drink. The larger leaf cut also makes it well suited to loose-leaf blends where the appearance of the botanical matters.

Yerba Mate Powder Organic
Yerba Mate Powder Organic is milled into a fine powder rather than supplied as cut leaf. This makes it better suited to applications where the ingredient needs to be blended directly into a finished product rather than removed after steeping. Powder is generally the most practical option for food manufacturing, powdered drink mixes and other dry formulations because it can be dispersed throughout a batch. Buyers should consider texture and handling requirements, as finely milled botanicals can naturally settle or clump during storage.

Yerba Mate Organic
Yerba Mate Organic is the most versatile option in the range. It is supplied as a coarse, unroasted leaf, retaining the bold, green and slightly bitter flavour commonly associated with traditional yerba mate. Choose this format if you want a general-purpose mate suitable for direct brewing, loose-leaf tea blends or larger-scale infusion.
Shop NowFrequently Asked Questions
Does yerba mate have caffeine?
Yes. Yerba mate naturally contains caffeine, generally reported at around 1 to 2% of the dried leaf by weight, along with smaller amounts of theobromine[1]. The amount in a finished drink can vary depending on factors such as the leaf grade, serving size, brewing method and steeping time, so published caffeine figures should be treated as indicative rather than as a fixed specification.
What is the difference between roasted and aged yerba mate?
Roasted and aged yerba mate differ mainly in how the leaf is processed after drying and the flavour profile this creates.
Roasting applies heat to the leaf, producing a darker colour and deeper toasted, earthy flavours while reducing some of mate’s fresh, grassy character. Ageing allows the dried leaf to mature over time, generally creating a smoother and more rounded flavour while retaining more of its traditional green character.
Choose roasted mate when you want a richer, toasted profile. Choose aged mate when you want a mellower version of traditional yerba mate without moving as far away from its characteristic flavour.
Is your yerba mate certified organic, and where is it sourced from?
Our yerba mate range is Certified Organic through ACO and processed in a HACCP-certified facility. Sourcing can vary between products and batches, so buyers requiring a particular country of origin should check the current product specification before ordering. Organic certification provides assurance that the ingredient has been produced and handled in accordance with applicable organic standards.
What does yerba mate taste like?
Traditional unroasted yerba mate has a bold, herbaceous and slightly bitter flavour, often compared with a strong green tea but with its own distinctive earthy character. The flavour varies by processing method. Roasted yerba mate develops deeper toasted notes, while aged yerba mate generally has a smoother and more rounded profile. This makes the choice of variant particularly important for tea blenders and beverage manufacturers developing a specific finished flavour.
What is the minimum order quantity for bulk yerba mate?
Minimum order quantities can vary depending on the yerba mate product, format and current availability. Smaller quantities may be suitable for sampling, product development and trial batches, while larger bulk quantities can be arranged for commercial production. Contact us with the variant, required volume and intended application so we can recommend the most suitable option.

Pairs Well With
Peppermint
Peppermint brings a cool, fresh lift that balances yerba mate’s naturally herbaceous and slightly bitter flavour profile. It works particularly well in refreshing tea blends, iced infusions and cold-brewed mate, including drinks inspired by traditional tereré.
Ginger
Ginger adds warmth and spice without overwhelming the green flavours of yerba mate. It is a versatile pairing for hot teas, functional blends and ready-to-drink beverages, particularly when combined with citrus or other bright flavours.
Hibiscus
Hibiscus gives yerba mate a tart, fruity flavour profile and a deep red colour, making it particularly useful in iced teas and ready-to-drink beverages. Its acidity can also help balance the bitterness of a stronger mate infusion.
Lemon Myrtle
Lemon myrtle adds a bright citrus aroma that contrasts well with yerba mate’s earthy, vegetal profile. It is a useful pairing for Australian tea blends and beverage formulations where a clean, fresh citrus character is wanted without adding fruit juice.
Cacao
Cacao pairs naturally with the deeper, roasted notes of roasted yerba mate. Together they create a richer flavour profile suited to warming tea blends, powdered beverages and formulations where a more rounded alternative to green, herbaceous mate is preferred.
Siberian Ginseng
Siberian ginseng has an earthy, root-like character that complements yerba mate in tonic-style and functional botanical blends. It is best used where the formulation is intended to have a distinctly herbal profile rather than a light or fruit-forward flavour.
