Digital probe tasting of Iberian ham with AI — the taster's verdict, piece by piece.
Tasting with a horse-bone probe is taster's knowledge that lives inside the taster's head. iLEAN Connect digitizes it — voice, photo and per-piece data — to rebuild the verdict piece by piece and turn it into a plant capability. The taster speaks; the system writes.
The taster's verdict is the cellar's most valuable asset — and its worst protected one.
Probing with a horse-bone needle is the final quality test on cured ham. A good taster smells a piece and decides in seconds whether it is ready, whether it needs more cellar time, whether it is premium or second grade, or whether it goes to rejects. That is decades of knowledge held in no system at all:
- The tasting notebook — notes in a pad or a spreadsheet that arrive late and often never arrive at all. The taster is not a typist.
- In-house vocabulary — "well fed", "sour tip", "short bed", "fatty aroma". Every cellar uses its own. When the taster retires, the terms go with them.
- No piece-by-piece traceability — the verdict, if it is written down at all, ends up grouped by consignment, not by piece. When a complaint comes in from the distributor, rebuilding what the taster said about that piece is impossible.
- No capture of the judgment — the veteran's eye and nose live in the person. The day they retire, half the cellar goes with them.
It is the clearest example of the library with no librarian: the information is there, but it is not joined up, not tied to the piece, and not in a format anyone can operate on. And the problem is not clumsiness — doing it by hand was simply impossible. That has just changed.
iLEAN Connect does not teach the taster — it listens to them and goes along with them.
The integration is not a magic button: what has changed is that it is now possible and affordable to capture the taster's voice live, tie it to the specific piece and leave it structured so the rest of the cellar can use it. iLEAN acts as the putty between the taster (the island of knowledge) and the systems you already have (ERP, MES, PDO dossier).
The taster speaks. Connect transcribes and structures. The agent cross-references with the batch. The person signs — always. When the taster retires, their judgment stays in the cellar as a permanent capability.
The iLEAN piece applied to digital probe tasting of Iberian ham:
- iLEAN Connect — earpiece + phone/tablet in full duplex. The taster speaks while probing, without breaking rhythm. The voice is transcribed at second zero, and a photo of the piece with the batch label ties the verdict to that specific piece. It also captures what arrives from outside: an email from the importer with a new retailer criterion, a WhatsApp from the cellar manager with a change in the vintage. It does not listen until the person activates it.
- The cellar's own vocabulary — Connect does not impose generic terms; it learns the taster's terms ("well fed", "sour tip", "short bed") and structures them as categories that belong to your cellar. The judgment is kept in their own words, not in borrowed ones.
- Agent — cross-references the verdict with the batch in the ERP, the hall and vintage from the MES, and the commercial destination. It builds a per-piece dossier ready for a PDO audit or a customer complaint. The taster signs; nothing goes out without a human signature.
Tasting notebook vs. digital probe tasting with iLEAN Connect
| Aspect | Tasting notebook | With iLEAN Connect |
|---|---|---|
| Recording the verdict | Pad or spreadsheet, after the fact | Voice transcribed at second zero |
| Traceability per piece | Grouped by consignment | Piece by piece, with photo and batch |
| The taster's terms | Only in their head | In-house vocabulary captured and structured |
| The taster's time | Taste + write | Taste and talk; the system writes |
| PDO dossier | Rebuilt by hand | Automatic, ready for the audit |
| Continuity when they retire | The judgment is lost | A library of verdicts with voice and photo |
Impact estimate for your plant — to be validated with your numbers.
The block below is an estimate to be validated with the specific data of your cellar. We put it forward so the committee has an order of magnitude; we refine it during the diagnostic.
- An Iberian ham cellar with one or two senior tasters, regular probing across thousands of pieces, and a PDO dossier that today is rebuilt by hand for the audit.
- Connect pilot (earpiece + phone/tablet + transcription + integration with the batch from the ERP and the hall from the MES/Excel). First value expected within a few weeks: the probing starts being recorded per piece from the very first round.
- Indicative payback between 4 and 8 months, depending on the time currently spent rebuilding dossiers and the cost of distributor complaints you cannot defend for lack of traceability.
- Hard lever: a reduction of ≥ 30% in the taster's administrative time (taster tasting, not typing), capture of the judgment as a plant asset, PDO dossier ready with nobody typing. Conservative figures, a defensible floor.
And the taster's reasonable doubt
“What if the AI mis-transcribes or invents a nuance?” — hallucination is a problem of free generation, not of anchored tasks. When the AI limits itself to transcribing voice and structuring the verdict against the cellar's own vocabulary, the best models brought error below 1.5%[1]. And even so, what is critical is never decided alone: the taster validates the transcription of the verdict before closing the piece. The three safety rings exist precisely for this.

What people ask about digital probe tasting of Iberian ham
What exactly is horse-bone probe tasting in Iberian ham?
The cala is the olfactory quality-control test used on cured ham: the taster inserts a probe —traditionally made of horse bone, sharpened to a bevel— at key points of the piece (babilla, maza, shank, contramaza) and smells it as it is withdrawn to assess curing, aromas and any defects. It is a method with no substitute, passed on from taster to taster, that decides whether the piece is ready to sell, needs more time in the cellar, or is rejected.
How do you digitize the tasting without forcing the taster to type?
With iLEAN Connect: the taster wears an earpiece and carries a phone or tablet online, full duplex. He speaks while probing — “babilla is good, acorn-fed aroma”, “maza has a sour tip”, “shank is short on curing” — and the system transcribes and structures it. A photo of the piece with the batch label ties the verdict to that specific piece. Zero keyboard, zero paper.
Does iLEAN Connect replace the taster or assist them?
It assists. The judgment still belongs to the taster — a nose cannot be delegated. What changes is that their verdict stops dying in a notebook and starts being a plant asset: every piece keeps its voice note, its photo and its verdict, cross-referenced with the vintage, the cure and the commercial destination. The AI does not decide; it collects, transcribes, structures and clears the way so the taster can do what they do best. The tool works for them, not on them.
What happens when the taster retires — is their judgment preserved?
That is exactly why Connect exists in this case. The biggest island in any cellar is the veteran's eye — and the taster's nose is its most expensive relative. Over months or years, Connect captures every verdict tied to the physical piece and the batch: the aromas they rated as good, the nuances they rejected, the in-house terms only they used. When they retire, the younger taster has a library of verdicts with voice and photos of the pieces — the judgment stays in the cellar.
How does digital tasting integrate with the ERP and the PDO dossier?
The agent cross-references the taster's verdict with the batch in the ERP, the hall and vintage from the cellar MES/Excel, and the commercial destination. The result is a per-piece dossier that builds itself: transcribed voice, photo, structured verdict, vintage and hall traceability. Useful for a PDO audit, for customer complaints, and for defending the premium category when you have to prove piece-by-piece quality control.
