Over a hundred years ago, along the old “Camino Real de la Yerba Mate”, our ancestors found the ideal soil for growing their future: work and home. Today, Las Marías, is a unique blend of countryside, farm, industry and village in the lush subtropics of Argentina. It is a place of particular beauty and, without a doubt, the perfect place to learn, step by step, all the secrets of superior mate and Argentinian tea. .

Las Marías is the world’s biggest producer of yerba mate – this is where Yerba Taragüí is born, a brand, synonymous with mate not only in Argentina. All stages of yerba mate production are undertaken with integrated agroindustrial practices of the highest quality. The company also produces the best tea in America, plants trees on a large-scale – operating one of the largest sawmills in the country. We also are at the forefront in cattle ranching and breeding, the traditional activity in this region, which was introduced by the Jesuits four centuries ago.

It could be understood that the main reason for thousands of visitors to come to Las Marías each year is because of its fascinating network of productive activities. However, once visitors arrive here, they discover its greatest charm: its people. Aside from the work, the many activities that make up the lives of the company’s members take place here: Homes, schools, health care and other services are interwoven with parks and gardens enhancing the beauty of the natural environment by creating peaceful spaces. Tree lined roads and trails connect these different areas, giving Las Marías a unique harmony that, without exception, enchant the visitor.



All visitors to Las Marías that arrive during visiting hours, are welcomed and invited to taste its products. At no charge, they can take a walk through the gardens and take a close-up view of the Mayoria, the old family home, which is now the emblem of the company.
