Features and International events
Susana Cárdenas Overstall is a freelance journalist who left behind the tropics of Ecuador for misty London where she has been living for the last six years. Deep inside, she misses the sound of the Pacific Ocean and walking among the cacao trees at her father’s farm in the province of Manabí. Her first encounter with fine cacao began at the age of 10, when her father taught her how to select and roast Arriba Nacional cacao beans in order to make homemade chocolate.
Before entering the world of cacao, Susana came from a communications background and is a frequent contributor to Latin American and Spanish publications.
Susana is currently Seventy%’s sole representative in Latin Americ, please contact her for any enquiries about events or workshops in the region.

As one of the most comprehensive chocolate sites in the world, Seventy% brings consumers, professionals and industry producers together as a community to learn the finer distinctions of cacao and chocolate and the importance of a direct connection from ‘bean to bar’. In doing so it helps support the continued growth and development of the fine cacao and chocolate market, from the ground up.
Seventy% also runs experiential chocolate events for consumer and corporate clients and our Slow Chocolate series of workshops, which will help develop your connoisseur chocolate senses.
