Yerba mate, a traditional South American caffeine-rich beverage, is renowned for its earthy and robust flavor profile, which can sometimes be quite bitter. For those who find the taste too intense, or simply prefer a sweeter brew, there are many ways to soften the flavor. This practice is known as mate dulce. The choices range from common household sweeteners to historical and culturally significant alternatives.
Traditional Sweeteners
For many, especially in Argentina, a touch of sugar is the classic way to prepare mate dulce. This method is straightforward and effective at cutting through the bitterness.
Sugar (White, Cane, Coconut)
- White Sugar: The most common and accessible option, providing simple sweetness without altering the flavor profile significantly. It dissolves easily in the hot water used for brewing.
- Cane Sugar: Popular in South America, cane sugar offers a more complex, caramel-like flavor compared to white sugar. It can add an extra layer of depth to the mate's natural earthy notes.
- Coconut Sugar: A natural alternative with a lower glycemic index and a mild coconut flavor. It's a milder sweetener that pairs well with yerba mate without overpowering it.
To use sugar, you can either add a spoonful directly to the gourd with the leaves before pouring the hot water, or dissolve it in a little hot water separately to avoid clogging the bombilla (the filtered straw).
Natural & Calorie-Free Sweeteners
For those who want sweetness without the calories, a variety of natural, low-impact sweeteners are excellent choices. These are often preferred for their minimal effect on blood sugar levels and potential health benefits.
Stevia Leaf and Powder
Stevia is arguably the most historically relevant sweetener for yerba mate. The Guaraní people, who first cultivated yerba mate, have a long tradition of using stevia leaves to sweeten their brew. Today, stevia is available in both powdered and leaf form. Powdered stevia is a zero-calorie, plant-based option that is extremely potent, so a very small amount is all that's needed. Using too much can result in a lingering, licorice-like aftertaste. The natural leaf offers a more subtle sweetness that can be brewed directly with the yerba mate leaves.
Honey
Honey adds a pleasant, floral, or caramel sweetness, depending on the type used. It's a natural option that also provides a boost of antioxidants and has a range of antibacterial properties. Since honey is a liquid, it's best to dissolve it in a separate container with warm water before adding it to the gourd, which prevents the bombilla from getting clogged.
Xylitol and Agave Nectar
Xylitol, or birch sugar, has about 40% fewer calories than table sugar and a low glycemic index. Its mild, cooling flavor pairs well with yerba mate, and it can be added directly to the dry leaves. Agave nectar provides a distinct, rich sweetness similar to honey or maple syrup and is another popular liquid option.
Flavoring with Fruits and Herbs
Beyond traditional and artificial sweeteners, you can add natural sweetness and complexity using fruits and herbs. Many ready-made blends on the market already incorporate these ingredients, but you can also experiment with your own additions.
Dried Fruits
Dried fruits like apple, orange peel, and berries release their natural sugars and flavors into the brew over time. Citrus peels, in particular, offer a sweet and tangy freshness that complements the earthy base. Tropical fruits like pineapple and mango can also be used to infuse an exotic, fruity sweetness.
Aromatic Herbs and Spices
Certain herbs and spices naturally contain sweet notes or enhance the perception of sweetness. Licorice root, for example, is known for its sweetening properties and provides an anise-like flavor. Anise and fennel seeds, vanilla bean, or a cinnamon stick can also add harmonious sweetness without relying on sugar. Combining yerba mate with herbs like chamomile or mint can not only sweeten the taste but also provide additional digestive benefits.
