four zones · complete distillery.
A CRT-registered tequila distillery has four critical fronts: agave cooking ovens (masonry or autoclave, 90-100°C × 24h), precise 30-35°C fermentation, barrel cellar for white-oak barrels (18-22°C / 60-75% RH), CRT chain-of-custody + CFE sub-metering. AstreaIoT covers all four with the same platform.
90-100°C × 24h agave cooking ovens
high-temperature PT100 probe per masonry oven or autoclave · continuous cooking curve log (typically 24-36h ramp + hold) · WhatsApp alert to master tequilero if out of range. Delayed CRT audit by documented curve. Temperature probe for extreme ranges.
30-35°C tinaja fermentation
T probe per fermentation tinaja (traditional wood, stainless steel, or cement) · continuous 3-5 day fermentation curve log · alert if out of range. Compatible with native yeasts (no active temperature control) or cultivated (with glycol jacket).
white-oak barrel cellar T+RH
T+RH probe per barrel room · target 18-22°C / 60-75% RH for reposado/añejo tequila · cellar manager dashboard + alert if out of range · trackable angel's share + defended aromatic profile. CRT-100% Agave audit backed.
CFE GDMTO sub-metering + chain-of-custody
main-panel meter with 12 current channels + 3 voltages · per-line CFE sub-metering (cooking · fermentation · distillation · packaging · cellar). Door sensor on chain-of-custody access points (cooking → fermentation → distillation → cellar → packaging) for CRT audit trail.
Out of scope: agave jima process (field) and fruit cutting. Also not fermentation with native vs cultivated yeasts — that's the master tequilero's decision. We integrate via Modbus with existing control systems.
what we protect · what we prevent.
- +Ovens with precise curve · well-cooked agave · maximum yield · CRT audit backed
- +Documented 30-35°C fermentation · defended tequila profile · controlled congeners
- +Validated barrel cellar T+RH · defended reposado/añejo profile · trackable angel's share
- +Per-line CFE GDMTO sub-metering · justified power factor · over a million pesos in annual savings
- +Auditable CRT chain-of-custody · NOM-006-SCFI compliant · backed "100% certified agave" brand narrative
- ✕Oven with wandering curve · undercooked agave · entire batch low yield · CRT investigation
- ✕Fermentation out of 30-35°C · tequila with metallic or too-fruity flavor · brand reputation crisis
- ✕Barrel cellar at 28°C summer without control · +15% angel's share · barrels with wrong profile
- ✕Low power factor in GDMTO without breakdown · invisible CFE penalty · capacitor bank without justification
- ✕CRT audit without documented chain-of-custody · loss of certification · catastrophic brand value
eight use cases · four critical areas.
for the master tequilero + cooking lead.
Master Tequilero + Cooking Lead + Production Director. Two cases · masonry oven with curve out of range during overnight cooking, modern autoclave with unbalanced burner. Yield + CRT audit.
for the master tequilero + fermentation lead.
Master Tequilero + Fermentation Lead + Production Director. Two cases · tinaja with high summer T without active control, slow fermentation due to low yeast activity. Profile + consistency.
for the cellar manager + master blender.
Cellar Manager + Master Blender + Production Director. Two cases · summer cellar with T+RH out of range, aging room with extreme low RH affecting barrels. Profile + angel's share.
for the CRT compliance officer + CFO.
CRT Compliance Officer + CFO + Production Director + Commercial Manager. Two cases · CRT audit without documented chain-of-custody, low GDMTO power factor without breakdown. Compliance + costs.
three compliances · one platform covers all three.
For multi-site distilleries (Cuervo Mundo Cuervo Tequila + La Rojeña, Sauza, Patrón La Hacienda), cross-site dashboard with compliance ranking + evidence snapshots for inspector.
from sensor to report · every five minutes · without human intervention
Five steps. They run in parallel across all your sites, all the time. When something crosses a threshold, the flow completes in under five minutes — alert delivered, response logged, inspector-ready evidence captured.
measure
Sensors measure temperature, humidity, current, door-open, leak and other magnitudes every five minutes — no operator required.
detect
The system compares each reading against the threshold configured per recipe · per site · per equipment. Threshold crossing triggers the flow.
alert
The alert routes to the right person via WhatsApp, email or push · per role and schedule configured.
respond
The operator acts from the dashboard or mobile app. The corrective action goes into an immutable log with timestamp + signature.
audit
Everything becomes part of the audit package · time series, critical events, corrective actions, NOM report ready in two clicks.
Five steps · no manual operators · no paperwork · no gaps.
five phases · per distillery.
site survey + distillery plan
2-3 daysTechnical visit + inventory of ovens (masonry + autoclaves), fermentation tinajas, barrel cellar, alembics, CFE panel · deployment plan with CRT chain-of-custody emphasis.
physical installation
4-7 daysOven PT100 probes + tinaja T probes + cellar T+RH probes + CFE three-phase meter + chain-of-custody door sensors · gateway with backup · without affecting production.
configuration + CRT integration
3-5 weeks (includes Custom Integration L3 with CRT-reporting systems if applicable)Cooking curves + fermentation ranges + cellar thresholds · CRT-audit + COFEPRIS report templates · internal compliance system integration.
team training
2 daysMaster Tequilero + Cooking Lead + Fermentation Lead + Cellar Manager + CRT Compliance + CFO + Production Director · each role trains on their flow.
30 days of support + first CRT audit
30 daysAstreaIoT specialist available · first monthly report with cooking + fermentation + cellar + chain-of-custody · first CRT audit backed with the platform.
For multi-site distilleries, per-site deployment with standardized BOM + cross-site chain-of-custody.
common questions · before the quote.
are CRT audits specifically backed?
Yes · pre-configured templates for CRT audit + automatable report with cooking + fermentation + cellar + chain-of-custody. CRT your Responsable Sanitario hands the evidence packet to the auditor (two-minute prep). Compatible with CRT-Blanco, CRT-Reposado, CRT-Añejo, CRT-Extra Añejo, CRT-100% Agave.
what about chain-of-custody from agave to bottle?
Door sensors + timestamp + immutable log on each process transition (cooking → fermentation → distillation → cellar → packaging). Per-batch evidence snapshot for inspector. Combined with your ERP it is complete traceability.
does the PT100 probe withstand masonry oven temperatures?
Yes · temperature probe (90-100°C operational, peaks up to 500°C) · refractory + resistant cable · 4-8 week lead time direct-import for the extended range if your oven has peaks. We confirm at site survey.
is complete NOM-006-SCFI compliance covered?
Yes · the platform backs the NOM-006-SCFI process points: cooking + fermentation + distillation + maturation + chain-of-custody. For non-electrically-monitorable points (tasting, sensory analysis), manual report integrated to dashboard.
how is pricing for a mid-sized tequila distillery?
Per-process model: SaaS fee per oven + tinaja + cellar + chain-of-custody + sub-metering. Approximately between several thousand and tens of thousands of pesos monthly depending on scale. 90-day Hybrid Pilot default.
is the "complete traceability" brand narrative defensible?
Yes · optional public dashboard for your website showing process in real time (anonymized) · QR-code per bottle links to its batch-specific snapshot · premium brand differentiation. Some premium houses already do this in Patrón / Cuervo Reserva de la Familia.
does it integrate with existing ERP systems (SAP, Oracle, Cuervo systems)?
Yes · REST API + webhook · integration with SAP, Oracle, proprietary systems. Consolidated production data for monthly reports + per-batch evidence snapshots for inspector.
