Botillo IGP Bierzo smoking and curing with AI — you don't replace the traditional smokehouse, you measure it.
Botillo IGP from El Bierzo cures fast but demands a lot: the smoke curve, the smokehouse temperature, the humidity and the per-piece weight set the characteristic aroma of the IGP. iLEAN Edge captures those variables and the agents propose the adjustment when a load does not behave like the previous ones. The person signs — the smokehouse never changes parameters on its own.
Slow smoking over firewood is honest craft — and that is exactly why it resists being measured by eye.
Botillo IGP from El Bierzo is a product with a short cure but a long list of judgment calls: five to seven days of slow smoking over hardwood plus air-drying. The classic problem is that every variable that matters lives on its own island:
- The firewood is not homogeneous — oak from one delivery does not burn the same as the next, and smoke density varies with the moisture in the wood and with the smokehouse draft.
- The stuffed raw material changes from batch to batch — the proportion of meats, rib, backbone, tail and tongue can vary within the IGP specification itself, and that changes how each piece takes up the smoke.
- The specification asks you to demonstrate all of it — and demonstrating it after the fact, by hand, with notebooks and signatures, is a serious amount of work.
The master knows this — he has known it all his life — but he cannot be opening the smokehouse every half hour. When the curve drifts and nobody catches it in time, the batch comes out with an irregular profile: a less pronounced aroma, uneven weight or, in the worst case, outside the IGP specification. And the customer can tell in a single bite that the botillo is not the one they know.
iLEAN does not want to modernize the smokehouse — it wants the craft to be provable with data.
The problem with botillo is not a lack of craft: it is craft that survives only inside the master's head. iLEAN acts as the putty between the traditional smokehouse, the batch recipe and the IGP specification, without asking you to change either the smokehouse or the ERP.
Edge measures smoke, temperature, humidity and weight. Connect captures the batch recipe and the firewood supplier's notices. The agent cross-checks against the specification and calls the master if a load does not fit. The person signs.
The iLEAN pieces applied to Botillo IGP from El Bierzo:
- Edge — temperature, humidity and smoke-density sensors in the smokehouse, plus weighing by rack or by trolley. It captures the real curve continuously. It works with no network: if the plant loses WiFi, Edge keeps measuring and recording, because an IGP cannot depend on connectivity.
- Connect — captures the batch recipe, the stuffed raw material, the firewood batch, the supplier's notices ("this oak is coming in drier") and everything that arrives by email, WhatsApp or phone call. At second zero, with nobody forwarding anything.
- Agent — cross-references the real curve against the expected curve and the IGP specification. If a load behaves differently from the previous ones, it proposes to the master curer that he check the draft, extend the smoking or adjust the rack. It does not change parameters on its own. The master validates and signs — the three rings guarantee human validation on anything critical.
Traditional smokehouse run by eye vs. smokehouse governed with iLEAN
| Aspect | Smoking by eye + the master's notebook | With iLEAN Edge + Connect + Agent |
|---|---|---|
| Capture of smoke/temperature/humidity | Spot checks, the master's intuition | Continuous, recorded by load and by batch |
| Weighing by rack | Manual, periodic | By rack, recorded against the curve |
| Cross-check recipe ↔ firewood ↔ curve | Mental, batch by batch | Automatic against the IGP specification and the history |
| Variation in the firewood | "This oak is different" — intuitive | Detected in the curve within the first hours |
| IGP file per batch | Rebuilt by hand for the audit | Automatic dossier with curves and signatures |
| Operation with no network | n/a | Edge keeps measuring with its own light |
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 plant. We put it forward so the committee has an order of magnitude; we refine it during the diagnostic.
- An El Bierzo cured-meat plant with 1-3 traditional hardwood smokehouses, several references (botillo IGP, botillo extra), working by season.
- Edge pilot on one smokehouse (temperature/humidity/smoke sensors + weighing + integration with the batch recipe from the ERP). First value expected within a few weeks.
- Indicative payback between 4 and 9 months, depending on the cost of an irregular batch and how often loads came out with a divergent smoke profile over the past year.
- Expected improvement floor: a reduction of ≥ 30% in the spread of the smoking profile between loads.
- The hard lever: one IGP batch rescued and the automatic file ready for the IGP audit.
And the master curer's reasonable doubt
“What if the AI proposes extending the smoking and the aroma goes too far?” — hallucination is a problem of free generation, not of anchored tasks. Cross-referencing the real curve against the expected curve and the IGP specification is an anchored task. In this kind of task, the best models brought error below 1.5% [1]. And even so, what is critical is never decided alone: iLEAN proposes, the master signs. The three safety rings exist precisely for this.

What people ask about Botillo IGP Bierzo, smoking and curing with AI
What does the Botillo del Bierzo IGP specification require during smoking?
The Botillo del Bierzo IGP specification regulates the raw material (pork meat and bones, rib, tail, backbone, shoulder, tongue), the marinade with salt, paprika and garlic, the stuffing into the pig's own caecum and, above all, a phase of slow smoking with hardwood (typically oak or holm oak from El Bierzo) followed by air-drying or a short cure. The smoke curve, the smokehouse temperature and humidity control are what give botillo from El Bierzo its characteristic aroma — and what the specification asks you to demonstrate.
How does iLEAN control the smoke curve in the botillo smokehouse?
iLEAN Edge installs temperature, humidity and smoke-density sensors in the smokehouse, and weighs the product by rack or by trolley. The agents cross the real curve against the batch recipe and the expected curve for that reference (botillo IGP, botillo extra, and so on). If temperature climbs too high, if smoke density drifts or if humidity drops too far, the system proposes it to the master curer through his own channel. The person signs — the smokehouse never changes parameters on its own.
What happens if the firewood is not uniform and the smoke varies between loads?
That is one of the classic challenges of artisanal hardwood smoking: oak from El Bierzo in one delivery does not burn the same as the next. Edge measures the real curve, not the ideal one. When the smoke varies, the agents record it by batch, cross it against the firewood's own data (when that information comes in through Connect) and propose to the master an adjustment in time or in draft. The master's judgment rules; the agents simply take away the tedious part of measuring and recording.
Does iLEAN work for a traditional cellar with no SCADA on the smokehouse?
Yes — that is the typical situation wherever botillo is made properly. Edge is installed as a capture layer on top of the traditional smokehouse, with its own temperature, humidity and smoke sensors. Connect captures the batch recipe and the firewood supplier's notices whether they come from the ERP, from the MES or from a scanned notebook. We do not ask you to change the smokehouse or the ERP; we fill the gaps. And Edge keeps measuring if the plant loses its network.
How much does an AI-governed botillo cure save?
With Botillo IGP from El Bierzo, the hard lever is not only waste — it is the difference between a batch with the El Bierzo aroma the customer expects and a batch you accept “as it comes out”. The estimate to be validated for a mid-sized plant: an Edge pilot on one smokehouse, first value within a few weeks, indicative payback of several months and a reduction floor of ≥ 30% on batches with an irregular smoking profile.
