The storage standards for bulk wine or spirits (散酒) typically involve the following key requirements, based on industry best practices and international regulations:
1. Temperature Control
Maintain a stable temperature between 10–20°C (50–68°F).Avoid sudden fluctuations to prevent oxidation or spoilage.2. Humidity
Relative humidity should be kept at 60–70% to prevent cork drying (if applicable) or label damage.3. Light Exposure
Store in dark or low-light conditions to prevent UV light from degrading the product.4. Ventilation
Ensure proper airflow to avoid accumulation of volatile compounds or mold growth.5. Container Requirements
Use stainless steel tanks, food-grade epoxy-lined vessels, or inert containers to prevent contamination.Seal containers tightly to minimize oxygen exposure.6. Hygiene & Sanitation
Storage areas must be clean, pest-free, and sanitized regularly.Avoid storing near chemicals or strong odors.7. Avoid Vibration
Protect from excessive movement or vibration to preserve stability.8. Quality Monitoring
Conduct regular checks for pH, alcohol content, microbial activity, and sensory qualities.9. Legal Compliance
Follow local regulations (e.g., FDA (USA), EU Food Safety Standards) and industry certifications (e.g., ISO 22000).10. Record-Keeping
Document batch numbers, storage dates, and inspection results for traceability.Key Differences by Product:
Wine: Requires stricter oxygen control (e.g., inert gas blanketing).High-Proof Spirits: Focus on explosion-proof storage for ethanol vapors.Always consult regional guidelines and product-specific requirements for precise standards.
