Auro 72h Yeast Fermentation Acaiá Peaberry
This Acaiá peaberry lot from Mio uses 70% overripe cherries - those that have begun drying on the tree - which bring extra complexity to the fermentation stage. The cherries were sealed in fermentation tanks for 72 hours, with Saccharomyces cerevisiae yeast used to drive the process. To boost microbial activity and flavour development, glucose and fructose were added as substrates.
Fermentation took place at Mio’s wet mill with tight control over time, temperature and oxygen levels. Afterward, the coffee was dried using a mix of raised beds, concrete patios, and ambient-air rotating dryers. Final prep included density separation and high-precision optical-electronic sorting.
