Yerba Mate

What is Yerba Mate?

Learn about its origin, benefits and how it is produced.

Yerba mate is a herbal infusion made from the leaves of the Ilex Paraguariensis, a tree that only grows in three countries of South America: Argentina (the world’s main producer), Brazil and Paraguay. In the wild it reaches a height of between 12 and 16 meters, although in order to harvest, the plants are pruned to a height of 3 meters. The harvest is done manually, starting in April/May, running through September. After harvesting, the tree regenerates and produces more leaves.

The drink itself is prepared in an extraordinary way. The most common, traditional way of drinking yerba mate is with a special cup designed for its purpose (the “mate”). The mate cup comes in several shapes and materials such as calabaza, wood or glass, among others. Ground yerba mate leaves are brewed with hot water in the mate cup and then drunk through a special straw (the “bombilla”). Read here about different ways on how to drink yerba mate.

How to drink Yerba Mate

Yerba mate has a herbal and slightly bitter taste. Some people prefer to add sugar or honey. You can drink it hot in the winter or cold in the summer; and you can even choose a flavoured yerba mate according to your taste.

Origin of yerba mate

The origins of yerba mate can be traced back to the Guarani natives, who used their leaves as a drink, an object of worship and a currency to trade with. The word “mate” comes from the Guarani term “Caa-mate”: “Caa” means plant or herb, and “mate” refers to the gourd they used to drink it.  For the Guaraní, the yerba mate tree is the tree par excellence, a gift from the Gods.

When the Spanish colonized South America, they learned from the Guarani the use and virtues of yerba mate, and spread its consumption over the whole colony. Later, the Jesuit missionaries introduced the crop in their small villages. They are the ones mainly responsible for cultivating and spreading the consumption of yerba mate. The habit of drinking mate has remained unchanged since ancient times.
