From the producer

Gabriel Castaño Buendía operates the La Granada farm in Acevedo, Huila, where he has become a key figure in the cultivation of Pink Bourbon coffee. After navigating difficult economic periods in the coffee industry, he returned to production and has since become a mentor and resource for the regional coffee community.

From the roaster

Onyx Coffee Lab highlights this lot for its vibrant and structured profile, achieved through a specific 90-hour whole cherry fermentation process. The roaster emphasizes the producer's legacy and his significant contributions to the regional coffee landscape.

Why this coffee is noteworthy

A family-produced Pink Bourbon from La Granada, where Gabriel Castaño helped establish and share the variety in southern Huila. The exact lot combines extended whole-cherry fermentation with a washed designation.

The honest process breakdown

WHAT DID THEY ACTUALLY
DO TO THIS COFFEE?

01
Extended whole-cherry fermentation

Onyx says intact cherries were fermented in bags for 90 hours before rinsing.

02
Drying conflict retained

The narrative says mechanical drying for three days; the structured field separately says Raised-Bed Dried.

What was added?

Huila relationship, 1,650 m elevation, December harvest month, exact flavor notes, roast classification, archived price and four evidence-labeled editorial sections.

What wasn't added?

No owner score, tasting verdict, harvest year, formal grade or independent public rating was invented. The drying conflict remains visible.

Why it matters

This corrects the prior 1,750 m description and separates roaster-provided cup language from an original review.

What you might taste

Onyx lists grapefruit, dried apricot, fig and walnut.
