Fermentation Tank Inspection Checklist for Breweries [FREE PDF]

Fermentation tank inspections are essential to maintaining product quality, worker safety, and regulatory compliance in brewery operations. FDA 21 CFR Part 110 Good Manufacturing Practices require that all equipment contacting food be maintained in a sanitary condition, while FSMA Preventive Controls (21 CFR Part 117) mandate documented process controls for equipment integrity and fermentation parameters. Additionally, OSHA 29 CFR 1910.146 governs confined space hazards associated with fermentat

Estimated Time: 25-40 minutes
Role: Brewmaster
Total Items: 40
Compliance: FDA 21 CFR Part 110.40 - Equipment and Utensils, FSMA 21 CFR Part 117.135 - Preventive Controls, TTB 27 CFR Part 25.55 - Brewery Premises Sanitary Requirements, OSHA 29 CFR 1910.146 - Permit-Required Confined Spaces, HACCP Codex Alimentarius CAC/RCP 1-1969 Rev.4 - CCP Monitoring Procedures

Tank Exterior & Structural Integrity

Assess the external condition of the fermentation tank including welds, insulation, supports, jackets, and general structural soundness.

Is the tank exterior free from visible dents, deformations, weld cracks, or corrosion?
Are tank support legs, base plates, and anchoring hardware in sound condition without visible cracking or corrosion?
Is the glycol cooling jacket free from leaks, bulging, or signs of pressure failure?
Are all exterior tank labels, capacity markings, and hazard placards legible and current?
Is insulation cladding intact with no visible gaps, tears, or moisture intrusion that could promote mold growth?

Manway, Hatches & Confined Space Safety

Inspect all tank access points for mechanical integrity and verify confined space safety protocols are in place.

Is the manway gasket in good condition (no cracking, compression set, or visible deterioration)?
Are manway clamps, bolts, and closure hardware fully engaged and torqued to specification?
Is a confined space entry permit required for tank access, and is the permit system active and documented?
Is atmospheric testing (O2, CO2, LEL) performed with calibrated equipment before any tank entry?
Is CO2 monitor/alarm equipment present and calibrated within the required service interval in the cellar area?

Fittings, Valves & Gaskets

Inspect all product-contact fittings, valves, sample cocks, and gaskets for mechanical condition, cleanliness, and food-grade compliance.

Are all tri-clamp fittings, butterfly valves, and sample ports free from product buildup, discoloration, or biofilm?
Are all gaskets confirmed to be food-grade material (FDA-compliant silicone, EPDM, or PTFE) and free from cuts or swelling?
Do all pressure relief valves (PRV) and carbonation stone ports operate freely without blockage or damage?
Are racking arms, dry-hop ports, and sample valves capped or sealed when not in use to prevent contamination ingress?
Are all product-contact fittings fabricated from 304 or 316 stainless steel (or equivalent food-grade material)?

Temperature & Pressure Control Systems

Verify that temperature and pressure monitoring and control systems are functioning correctly and calibrated.

Is the fermentation temperature currently within the target range specified in the batch recipe?
Is the temperature probe/RTD calibration current within the required calibration interval?
Is the glycol supply temperature and chiller pressure functioning within normal operating parameters?
Is current tank headspace pressure within the specified range for this fermentation stage?
Are pressure gauges legible, undamaged, and calibrated within the required service interval?

Active Fermentation Process Monitoring

Evaluate current fermentation progress, yeast health indicators, and product quality parameters.

Has specific gravity (or Brix/Plato) been measured and is attenuation progressing per the expected fermentation curve?
Is CO2 evolution visible and consistent with expected fermentation activity for current stage?
Has a sensory evaluation (aroma check) been performed to confirm absence of off-flavors or contamination indicators?
Has wort pH been checked and confirmed within acceptable range for yeast health and product specification?
Has yeast pitch rate, viability, and vitality been documented at time of pitching for this batch?

Vent, Blow-Off & CO2 Recovery Systems

Inspect all tank venting, blow-off tubes, and CO2 management systems for proper operation and contamination prevention.

Is the blow-off tube or vent system unobstructed and freely venting excess CO2 and foam?
Is the blow-off vessel or collection bucket clean and emptied to prevent backflow of contaminated liquid into the tank?
Is the spunding valve (if applicable) set to the correct pressure and operating without leaks?
If connected to a CO2 recovery system, are all recovery lines, compressor pre-filters, and connections in leak-free condition?
Are cellar CO2 warning alarms tested and confirmed operational since last verification date?

Dry Hop Additions & Adjunct Management

Inspect dry hop addition ports, adjunct handling, and post-addition tank sealing to ensure product safety and contamination prevention.

Were dry hop additions made using hops that have been inspected for mold, moisture, and foreign material?
Was the dry hop port sanitized immediately before and re-sealed immediately after the addition?
Were hop addition quantities, timing, and lot numbers documented per batch recipe and traceability requirements?
Has the fermentation tank been inspected for excessive hop blowout or blocked sample/racking ports following dry hop additions?
Are all adjunct ingredient storage areas (hop pellet cold storage, fruit addition prep) maintained at required temperatures and conditions?

Documentation, Records & Corrective Actions

Verify that all fermentation tank inspection findings, process data, and any corrective actions are properly recorded and accessible.

Has all fermentation process data (gravity, temperature, pressure, pH) been logged in the batch record for this inspection period?
Were any deviations from target fermentation parameters observed and documented with corrective actions taken?
Has the tank inspection been recorded in the equipment maintenance log with findings and any repairs noted?
Are all records from this inspection retained in a retrievable format for a minimum of 2 years?
Is this inspection report reviewed and signed by a qualified supervisor or Brewmaster before filing?
