María José Granier fell in love with the old vines of the high-altitude Cinti Valley at first sight. A passionate advocate of arboreal viticulture as well as historic varieties such as Negra Criolla, Moscatel de Alejandría and Vischoquena, she and her winemaking sister, Mercedes, have helped to made Jardín Oculto one of the best bodegas in Bolivia. I caught up with the two of them to learn more about the country’s increasingly exciting wine scene. My apologies for the quality of the recording at the Bolivian end.

To read more about Mercedes, María José and Jardín Oculto have a look at the winery's website. You can also follow them on Instagram at @jardinocultowines.
