Wine Bottling: Precision and Gentleness
Wine bottling demands equipment that handles the product with extreme care to preserve quality, aroma, and clarity. Unlike high-speed water or soft drink lines, wine bottling prioritises gentle handling, oxygen exclusion, and precise fill levels over raw speed.
Wine Filler Technologies
| Technology | Best For | Speed | O₂ Pickup |
|---|---|---|---|
| Gravity filler | Still wines | Up to 8,000 BPH | Moderate |
| Vacuum filler | Still wines, premium | Up to 6,000 BPH | Low |
| Isobaric filler | Sparkling wines | Up to 12,000 BPH | Very low |
| Slight vacuum | Table wines | Up to 15,000 BPH | Low-moderate |
Corking and Closure Systems
Wine closure equipment includes cork inserters (natural and synthetic), screw-cap applicators (ROPP heads), and sparkling wine wirehood applicators. Inspect jaw condition on cork inserters, compression uniformity, and cork feed reliability.
Capsule and Label Application
Wine lines typically include capsule applicators (PVC, aluminium, or tin capsules) and precision labellers for front, back, and neck labels. Used capsule spinners should be checked for head alignment and heat distribution uniformity on shrink capsules.
Inert Gas Management
Quality wine bottling requires nitrogen or CO₂ blanketing at multiple points: pre-evacuation of empty bottles, headspace flushing after filling, and sometimes tank blanketing. Verify gas injection systems are functional and properly calibrated.
Key Inspection Points for Wine Lines
Wine Line Checklist
- Product-contact surface condition (stainless steel quality)
- Dissolved oxygen pickup measurement during trial run
- Fill level accuracy (wine regulations specify fill tolerances)
- Cork insertion depth consistency
- Vacuum circuit integrity on vacuum fillers
- Gas management system functionality
- CIP circuit completeness for product-contact paths
- Gentle container handling through all transfers
Frequently asked questions
What filling technology is best for wine?
Gravity or vacuum fillers are preferred for still wines. Isobaric fillers are required for sparkling wines. The choice depends on wine type, production volume, and quality requirements.
Should I buy a monoblock or separate machines?
Monoblocks (filler-corker combinations) save space and reduce transfer risks. Separate machines offer more flexibility for different closure types but require more floor space.
How much does a used wine bottling line cost?
Small wine lines (1,500–3,000 BPH) start from €30,000–€80,000. Medium lines (4,000–8,000 BPH) range from €80,000 to €250,000. High-speed premium lines exceed €300,000.
