Mio is a distinguished producer and exporter established in 2020 in Monte Santo de Minas, Brazil. Managing a 1,589-hectare estate, Mio balances innovation with sustainability by dedicating equal land to coffee cultivation and native forest preservation. They utilise advanced technology and satellite imagery to ensure 100% traceability from seed to export. Specialising in experimental lots like this 72h yeast-fermented Acaiá peaberry, Mio manages every stage of production at their state-of-the-art mill.

Mio processed this lot using 70% overripe cherries that had begun drying on the tree to enhance complexity. These were sealed in tanks for a 72-hour fermentation inoculated with Saccharomyces cerevisiae yeast. To boost microbial activity and flavour development, glucose and fructose were added as substrates under tight temperature and oxygen controls. Afterwards, the coffee was dried using a mix of raised beds, patios, and rotating dryers before undergoing precision optical-electronic sorting to ensure elite quality.

Acaiá is a Brazilian cultivar developed by the Instituto Agronômico de Campinas (IAC) from Mundo Novo, a natural cross of Bourbon and Typica. Selected since the mid-20th century, it is prized for its large beans, consistent yields, and balanced cup quality. This specific lot features the Acaiá Peaberry varietal, grown at 900–1100 masl. While Acaiá is typically a commercial variety supporting Brazil’s production infrastructure, Mio’s experimental fermentation has transformed it into an exceptional 89.5-score specialty coffee.

Brazil is typically known for its signature smooth, sweet, low acidity profiles, with notes of milk chocolate, roasted nuts, caramel, and butterscotch. Brazil naturals are the foundation for many rich espresso blends. But this 89.5-score coffee with its experimental fermentation challenges the Brazilian stereotype, offering exotic complexity while retaining a classic "big Brazil body". The Auro does not disappoint and we were surprised at its versatility, from espresso to filter it delighted us in every cup. If you think you know Brazil, this innovative modern producer will re-frame your perceptions.
