Fazenda Um was established in 2009 when Stefano Um, the son of South Korean immigrants to Brazil, purchased what was then an abandoned farm in South of Minas Gerais. With no prior background in coffee farming, Stefano began producing coffee with a deep passion for quality and traceability, connecting initially with Asian specialty buyers and quickly developing a reputation for meticulous lot management and consistent processing discipline. The farm's name, translating simply as Farm One, reflects Stefano's philosophy of singular focus on quality above all else.

Under Stefano's guidance, Fazenda Um developed a specialty program around the Catucai 785 variety – a Catuai x Icatu hybrid well adapted to the South of Minas region – processing it through carefully managed pulped natural (honey) methods that retain mucilage on the parchment during drying to develop sweetness and body. Fazenda Um gained global recognition in June 2023 when Stefano's son Boram Um became the 23rd World Barista Champion and the first ever winner from Brazil – and the first champion to win using a coffee produced on their own family farm. This achievement brought unprecedented international attention to the farm and validated the extraordinary quality potential of Brazilian specialty coffee at the highest competitive level.
