Long before he was Colombino's most trusted partner on the ground in Colombia, Julián was already one of the most respected voices in Colombian coffee fermentation: author of the book "¡Al grano!," a top-three finisher in world cup-tasting competition, and founder of Estudio de Café Online, the first global platform dedicated to coffee education.

He developed his own controlled-fermentation method, teaching producers across Colombia and beyond how to build a simple bioreactor and ferment coffee with real precision, training a new generation of farmers in consistency and flavor clarity.

Since 2019, Julián has been Colombino's strongest connection in Colombia, our in-country partner helping source coffee directly from growers we trust and he has trained.

The Muscat honey process lot we carry isn't just coffee he helped source. It's grown on his own family's farm and processed by his own hands, using the same fermentation science he's spent his career teaching to others.

Duberney is a third-generation coffee farmer who learned the trade from his father; his mother passed away when he was a young child, and he was raised by other relatives.

In 2004 he inherited his mother's farm -bare land, with no coffee plants and no buildings at all- and began building it from nothing alongside his wife and their two children.

For five years he rode six hours by motorcycle every Friday to complete a degree in Forest and Agronomic Science, knowledge he brought straight back to the farm. In 2014 he planted his first Geisha trees, at an altitude of over 2,000 meters -a decision that paid off: 6th place in the 2017 Cup of Excellence, then 2nd place in 2018, and eventually the number one spot in Colombia's national ranking, the culmination of years of relentless work at his farm, Finca Montreal
