WHAT DID THEY ACTUALLY
DO TO THIS COFFEE?
Juan Peña produced this Typica lot at Hacienda La Papaya in Ecuador.
The coffee is cataloged as an anaerobic natural, meaning the fruit remained with the seeds through the fermentation/drying pathway rather than being fully washed before drying.
Onyx’s listing says the coffee underwent limited-oxygen fermentation in Ecuadorian rum barrels. The exact duration, barrel history, drying method, and microbial protocol are not published in the sources reviewed.
No fruit, flavoring, or other ingredient is disclosed as added to the coffee. Contact with a rum barrel is part of the processing environment.
Raw wine and ripe berries are tasting descriptors, not declared additives.
The barrel environment and limited oxygen can shape fermentation conditions and the coffee’s aromatic profile, while exact sensory outcomes still depend on the lot and execution.
Onyx lists raw wine and ripe berries.

What the internet is saying about this coffee

Other roasters, same producer.
These coffees come from the same producer or farm, offered by other roasters. We never automatically declare two offerings the exact same coffee — a match requires lot, harvest and traceability details. Even a true same-lot pair can taste different: roast approach, freshness, rest and brewing all reshape the cup.
