From the producer

The exact release identifies El Diviso in Huila and the Lasso brothers as the production context. Public exact-lot sources do not state the fermentation duration, drying method, harvest date, or elevation.

From the roaster

Onyx’s archived brew guide classifies this release as anaerobic washed, labels the roast Moderate, and publishes lemon candy, tangerine, starfruit, and rose as tasting notes.

Why this coffee is noteworthy

A Gesha from El Diviso presented through an anaerobic-washed process; its roaster-published profile centers on bright citrus, tropical fruit, and rose.

Coffee profile

In the database. Not tasted. Not scored.

This coffee is in our database because we can reliably document it — but we haven't tasted and scored it yet, and we never publish a score we haven't earned.

Outside reviews and internet discussion — is kept clearly separate from our own review. When we taste it, our full review appears here.

The internet pulse

What the internet is saying about this coffee

Research complete — no qualifying reviews yet

Our research pipeline scanned public reviews, videos, forums and discussions for this coffee (last pass 2026-10-26) and found no independent review of this exact release that meets our verification standards. When qualifying sources appear, they'll be published here.

What we found

Non-exact, seller, directory, generic-roaster, different-release, duplicate, and older-release sources were excluded. No qualifying independent exact-release review remains.

Same coffee, different roaster?

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.
