Wine and Cider Production: Tank Selection and Installation Guide
Wine and Cider Production
Small-scale wine, cider, and mead producers use food-grade polyethylene tanks for fermentation, cold stabilization, blending, and storage. While stainless steel is the industry standard for premium wine production, polyethylene tanks serve excellently for fruit processing, pressing, cold settling, and bulk storage where the cost of stainless is prohibitive. FDA-approved polyethylene is inert, easy to clean, and available in sizes from 10 gallons to thousands of gallons.
Why Tank Selection Matters for Wine and Cider Production
Not every polyethylene tank works for every application. The wrong tank can mean chemical incompatibility, premature failure, regulatory violations, or simply wasted money on features you don't need. This guide walks you through the specific requirements for wine and cider production and matches you with the right tank from our catalog.
Key Requirements
- FDA Approved — Mandatory for any food-contact vessel. All tanks used for wine, cider, or mead production must be food-grade.
- Drainage — Complete drainage prevents residual wine from spoiling and contaminating the next batch.
- Temperature — Polyethylene provides some insulation but cannot be actively cooled like stainless steel jackets. Monitor fermentation temperatures.
- Cleaning — Smooth polyethylene interior cleans easily with standard winery sanitizers (citric acid, SO2, peracetic acid).
Recommended Tank Types
Vertical Storage Tanks
Bulk juice and wine storage, cold settling, and blending operations.

Cone Bottom Tanks
Ideal for fermentation — cone bottoms allow yeast sediment (lees) drainage without racking.

Installation Considerations for Wine and Cider Production
Oxygen Management
Polyethylene is slightly oxygen-permeable, unlike stainless steel. This makes poly tanks suitable for fermentation (where some oxygen is beneficial) and short-term storage, but less ideal for extended aging where oxidation must be minimized. For aging, consider stainless steel or oak barrels.
Regulatory Compliance
Commercial winemaking is regulated by the TTB (Alcohol and Tobacco Tax and Trade Bureau). All production equipment must meet food-grade standards. Keep documentation of your tank's FDA certification for TTB inspections.
Sizing Your Tank
Tank sizing for wine and cider production depends on your usage rate, refill frequency, and peak demand. The general formula is:
Required Capacity = Daily Usage × Days Between Refills × 1.2 Safety Factor
The 1.2 safety factor accounts for peak usage days, delivery delays, and the fact that you should never run a tank completely dry (the sediment at the bottom can clog fittings and pumps). If your application has seasonal peaks, size for peak demand rather than average demand.
Maintenance Specific to Wine and Cider Production
Standard polyethylene tank maintenance applies: quarterly visual inspection, fitting checks, foundation verification, and vent maintenance. For wine and cider production specifically, pay extra attention to:
- Chemical compatibility: If you change chemicals or suppliers, verify the new formulation is compatible with polyethylene and within the tank's specific gravity rating before adding it to the tank.
- Residue buildup: Some liquids leave residue on tank walls over time. Annual interior inspection and cleaning prevents buildup from affecting liquid quality or reducing effective capacity.
- Fitting condition: Applications with frequent connect/disconnect cycles wear fittings faster. Replace threaded fittings at the first sign of thread damage — a cross-threaded or stripped fitting is a leak waiting to happen.
- Secondary containment: If required by your local regulations, inspect containment berms, dikes, or trays during each tank inspection. Secondary containment only works if it's intact.
Frequently Asked Questions
What size tank do I need for wine and cider production?
Start with your daily usage rate and multiply by the number of days between refills, then add 20% for safety margin. For example, if you use 50 gallons per day and refill weekly, you need: 50 × 7 × 1.2 = 420 gallons minimum. Round up to the next standard size — in this case, 500 gallons.
Do I need a chemical-rated tank or a water-only tank?
If you are storing anything other than clean water, choose a chemical-rated tank (SG 1.5 or higher). The thicker walls and higher material rating provide safety margin for chemical exposure, and you won't need to replace the tank if you switch liquids later. Water-only tanks save money but limit your future options.
What permits do I need?
Permit requirements depend on your location, the tank size, and what you are storing. Water storage typically requires no permits below 5,000 gallons. Chemical storage often requires permits, secondary containment, and fire marshal review. Agricultural exemptions may apply for farm chemical storage. Always check with your local building department and fire authority before installation.
Can I install the tank myself?
For tanks under 500 gallons, DIY installation is straightforward if you follow proper site preparation and plumbing practices. For larger tanks, we recommend professional installation — the weight involved creates safety risks, and improper placement can void the warranty. Either way, a proper foundation is non-negotiable.
How do I handle delivery and placement?
Small tanks (under 200 gallons) ship via UPS/FedEx ground. Mid-size tanks (200-1000 gallons) ship LTL on a pallet — you'll need a forklift or request liftgate delivery. Large tanks (1000+ gallons) ship via flatbed and require equipment for unloading. Call us to coordinate delivery logistics for your specific site conditions.
