Why it matters
Without verification, incomplete sanitation can lead to taint, off-odors, or spoilage, risking rejected lots, unwanted ageing notes, and inconsistent tasting experiences due to unpredictable barrel conditions.
From design to safety
Design
AI design for sanitation workflow
Define data interfaces from barrel washers, ozone sensors, steam controls, sulphur disc usage, cleaning log capture, retirement records, and schemas to support automated sanitation verification, audit trails.
- barrel washer
- ozone generator
- steam boiler
Build
Install sensors and logging contracts
Install inline flow meters, steam temperature probes, ozone analyzers, pressure sensors, connect cleaning log APIs, establish retirement protocols, and create data schemas for future AI scoring, alerts, and audit reporting.

- steam boiler
- cleaning logs system
Operation
Live monitoring of washing cycles
During wash, ageing, and storage phases, AI reads cycle times, temperatures, ozone concentrations, pH clues, and logging events to trigger corrective steps, validate sanitation, and maintain documented records.
- barrel washer
- ozone generator
- cleaning logs system
Maintenance
Routine calibration and calibration checks
Regular calibration of sensors, validation of log integrity, and inspection of retirement thresholds ensure data accuracy, traceability, and ongoing compliance with HACCP, appellation rules, and internal SOPs.

Safety
Safety checks and regulatory compliance
AI flags potential gas build-ups, ensures proper ventilation, and informs qualified personnel for CO2 and confined-space controls, with traceable safety records and SOP alignment to regulatory bodies.

Part by part
- 1
barrel washer
- Watch for
- Unbalanced wash cycles, residual moisture, or leaks in hoses or seals, or misaligned spray arms.
- AI action
- If cycle time or pressure deviates, pause wash and alert operator with sensor readouts.
- 2
ozone generator
- Watch for
- Ozone concentration drift, incomplete residuals, venting failures, or leak in supply line.
- AI action
- If ppm exceeds threshold, throttle output, trigger ventilation, and log event with timestamp.
- 3
steam boiler
- Watch for
- Steam temperature outside setpoint, boiler erosion, inlet fouling, or burner flame instability.
- AI action
- Adjust heat setpoint, initiate purge sequence, and log energy use.
- 4
sulphur disc diffuser
- Watch for
- Uneven sulphur disc contact, oxidation risk, incorrect placement, or disc aging.
- AI action
- Reorder discs in rack, reseat, and log usage with batch ID.
- 5
cleaning logs system
- Watch for
- Missing or inconsistent sanitation records, timestamp gaps, failed barcode scans, or device offline.
- AI action
- Flag missing entries, auto-generate audit-ready report, and assign corrective task.
- 6
barrel retirement protocol
- Watch for
- Overdue barrel retirement, storage conflicts, inaccurate ageing notes, or mislabelling origin.
- AI action
- Flag barrels for retirement, update ERP inventory, and generate disposition notes with reason.
Worked example
Catching a residue trace before ageing
Illustrative scenario with sample data.
A boutique operation wants to ensure barrels entering ageing have no sanitizer residue that could affect oxygen transfer and aroma.
Signal in
BarrelID: B-204; washCycle: 2; tempSet: 85C; ozonePPM: 1.5; sulphurDisc: S-03; logOK: true; retirementFlag: false; cycleStart: 2026-11-01 08:00; cycleEnd: 2026-11-01 08:12; phIndicator: OK; residualOzone: 0.8; lastAudit: 2026-10-28
System out
Alert: residue detected in B-204 wash line; action: extend wash by 90 seconds, recheck ozone, log extended cycle, update retirement check, timestamp 2026-11-01 08:13.
Human sign-off: Cellar supervisor reviews the alert, approves extended wash, saves the extended cycle in the cleaning logs, and informs QC for sampling.
How to roll it out
Phase 1
Weeks 1 to 4
Baseline data architecture and sensor integration are validated with pilot barrels, including cross-checking plume models and log integrity.
Phase 2
Weeks 5 to 8
Full data pipeline and logging are active; initial automated alerts are tested, with stratified risk rules for high-value ageing lots.
Phase 3
Weeks 9 to 12
Operational governance and audit-ready reports are in place for ongoing vintages, with archival policies and disaster recovery in place.
Where people stay in charge
- Decisions on halting a wash cycle must be made by the cellar master or QA lead with final sign-off from the winemaker.
- All changes to sanitation procedures require approval by the HACCP coordinator and appellation compliance officer before implementation.
- Sensor thresholds and disablements require sign-off by the safety officer and winemaker, documented in the change log.
Questions owners and crews ask
What sensors are used to verify barrel sanitation?
The system uses temperature sensors, flow meters, ozone concentration sensors, humidity probes, and logging endpoints to verify sanitation integrity and create a traceable record.
Who approves sanitation corrections before they’re applied?
The cellar master or QA manager must approve any corrective wash steps and updated logs before proceeding.
How is compliance with HACCP documented?
All sanitation events, sensor readings, and operator actions are timestamped and exported to an audit-ready report aligned with HACCP principles.
What happens if a log entry is missing or corrupted?
The system flags the gap, surfaces a remediation task, and requires supervisor sign-off before continuing.
