We’re proud to present this exceptional competition lot of Chiroso — a rare Ethiopian landrace mutation — from our friend Nestor Lasso at El Diviso. Grown in the highlands of Huila, Colombia, Chiroso is known for its elongated cherries and distinctive flavour profile. This lot delivers a vibrant cup, with notes of bright tropical fruit, chocolate, and a cooling touch of menthol. Nestor’s precise and innovative approach to processing is on full display here. Ripe cherries were manually selected, disinfected, and floated to remove any defects. Fermentation took place in carefully controlled stages: beginning with 36 hours of aerobic oxidation, followed by 48 hours of anaerobic fermentation at 17–20 °C, and then 24 hours of submerged fermentation using recirculated leachates at 17–23 °C, with constant circulation. The coffee was then subjected to a thermal shock at 65–70 °C to halt microbial activity and lock in flavour. Drying was carried out in a sealed environment to protect delicate aromatics, with a maximum temperature of 37 °C and a final moisture content of 10–11%. This is the first time we’re showcasing Chiroso from El Diviso — a beautifully executed lot from one of Colombia’s most forward-thinking producers.
Eight years ago, brothers Nestor and Adrian Lasso made a bold decision: rather than following the traditional methods passed down by their parents, they chose to explore the world of specialty coffee and experimental processing. Today, at just 25 and 27, they’ve become part of a new generation of Colombian producers pushing the boundaries of quality and innovation. Together with Jhoan Vergara, another young producer from a coffee-farming family, they founded El Diviso — a project that brings together their two family farms: El Diviso (Lasso brothers) and Las Flores (Vergara), near Pitalito, in southern Huila. This partnership has allowed them to pool their knowledge, resources, and passion to consistently produce exceptional coffees. Six years ago, the team began working closely with Cat and Pierre, founders of CATA Export, to refine fermentation techniques and develop protocols that would elevate their coffees for the international market. This collaboration has required time, trust, and significant investment — but the results speak for themselves. Their coffees have become a fixture in barista competitions across Europe, and around the world. Today, Finca El Diviso and CATA Export operate as a single, forward-thinking unit, with shared goals and a deep commitment to quality, education, and transparency. The friendship between Nestor and Cat embodies the values at the heart of CATA’s mission: building meaningful, long-term relationships that support the next generation of producers and help them thrive. We’re proud to continue showcasing coffees from El Diviso — not only for their exceptional cup profiles, but for the spirit of progress and collaboration they represent.
