Fermentation
Onyx identifies the exact release as washed and describes La Riviera’s close monitoring of fermentation variables and farm-level yeast-inoculation work. It does not publish this SL28 lot’s fermentation duration, yeast strain, vessel, oxygen conditions, or washing sequence, so the treatment is not classified more specifically.

Why some details are blank
  • lot-specific fermentationOnyx discusses fermentation monitoring and yeast work at La Riviera but does not publish this SL28 lot’s duration, strain, vessel, oxygen conditions, or confirm a bioreactor treatment.
  • washing chronologyWashed processing is confirmed, but the exact depulping, fermentation, washing, soaking, and water-contact sequence is not published.
  • drying durationRaised-bed drying is confirmed; duration, shade, bed depth, and final moisture are not published for this lot.
  • harvest yearThe numbered release states September without a crop year; the September 2024 date belongs to an older unnumbered release and was not transferred.
  • formal gradeOnyx publishes an 87.5 green-cupping score but no formal export or green grade for the release.
  • roast dateOnyx publishes the roaster and Agtron measurement but the archived roast-profile date and batch fields are empty.
  • independent exact-release sentimentLocated independent/catalog pages provide no qualifying exact-release tasting score or written review.
  • owner tasting inputNo owner score, observations, approval, verdict, or review date is recorded.

From the producer

Julio Madrid and Julio Quiceno have been refining their coffee production at La Riviera since 2013, focusing on cutting-edge fermentation techniques to enhance the complexity and balance of their crops.

From the roaster

Onyx archives this `-26` release at $62 for 10 oz / 283 g, roasted Moderate on a Diedrich CR-35 to ground Agtron 125.5, with prune, black tea, nectarine, and juicy notes.

Why this coffee is noteworthy

A Kenyan SL28 acclimated to Finca La Riviera’s 1,750-meter Risaralda environment, paired with unusually detailed Onyx roast, extraction, and trade-transparency documentation while keeping the exact fermentation boundary explicit.

The honest process breakdown

WHAT DID THEY ACTUALLY
DO TO THIS COFFEE?

01
Exact release identity

The `-26` page is the Moderate, ground-Agtron-125.5 release with prune, black tea, nectarine, and juicy notes; the older Expressive Dark archive is retained only as a separate historical version.

02
Washed processing

Onyx identifies this exact release as washed and raised-bed dried, but does not publish the lot-specific fermentation duration, vessel, inoculum, oxygen conditions, washing sequence, or drying duration.

03
Roasting and extraction

Onyx roasted the coffee on a Diedrich CR-35 and published exact filter and espresso starting recipes.

What was added?

Onyx discusses monitored fermentation and yeast inoculation at La Riviera, but no fruit, flavoring, commercial inoculum identity, or exact lot-level additive is documented for this SL28 release.

What wasn't added?

No fermentation duration, yeast strain, bioreactor treatment, washing chronology, drying duration, crop year, roast date, formal grade, or independent sentiment score was inferred.

Why it matters

Keeping the numbered and unnumbered releases separate prevents the older roast, notes, harvest year, and unreliable 312 g catalog weight from contaminating the `-26` record.

What you might taste

Prune, black tea, nectarine, and a juicy structure.

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 2026-11-07) 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

The Press is a directly relevant commerce catalog, not an independent tasting review. TheBeanGeek has no ratings. Cherrybook’s 60 is an evidence index partly built from general roaster reputation and non-exact Reddit material, while its notes and 312 g weight correspond to or conflate the older release; no numerical sentiment was added.

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.
