Brewery Packaging: A Critical Quality Control Point
Beer packaging is widely recognised as the most technically demanding application in the beverage filling industry. Unlike water or soft drinks, beer is a living product that is extremely sensitive to oxygen exposure, light, temperature, and microbiological contamination. Every component of the packaging line must be designed and maintained to protect beer quality throughout the filling process.
The brewing industry operates three primary packaging formats: glass bottles (returnable and one-way), aluminium cans, and PET bottles (primarily for emerging markets). Each format requires specific filling technology, and the choice impacts product shelf life, brand perception, and production costs.
Used brewery packaging lines represent significant value for craft breweries scaling up production, regional breweries expanding capacity, and international brewing groups establishing operations in new markets. The heavy-duty construction required for beer filling means that used brewery equipment often has decades of service life remaining when properly maintained.
Beer Filling Technology: Oxygen Is the Enemy
The primary technical challenge in beer filling is minimising dissolved oxygen (DO) pickup. Oxygen causes beer staling, producing unwanted cardboard-like flavours, darkening colour, and reducing shelf life. Modern beer fillers are designed to achieve total packaged oxygen (TPO) levels below 100 ppb, with higher-specification fillers achieving below 50 ppb.
Counter-pressure (isobaric) filling: Standard for all carbonated beer. The container is evacuated of air, purged with CO2 (often double or triple pre-evacuation), pressurised to filling pressure, and filled under isobaric conditions. After filling, the headspace is fobbed with a high-pressure water jet to create foam that expels residual air before capping.
Key beer filler manufacturers:
- Krones: Modulfill and Volumetic series — the global established manufacturer for brewery fillers
- KHS: Innofill Glass DRS and Innofill Can DVD — designed for low-oxygen filling performance
- GEA (Huppmann/Tuchenhagen): Specialised brewery filling technology with outstanding DO performance
- Bertolaso: Traditional Italian manufacturer with strong presence in wine and beer filling
- Simonazzi (now Sidel): Historical brewery filling installations, widely available in the used market
Fobbing devices: The high-pressure water injection device that creates controlled foam after filling. Critical for expelling headspace oxygen. Condition and alignment of fobbing nozzles significantly impact TPO results.
Under-lid gassing: CO2 injection under the crown cap or can lid immediately before closing. Displaces residual air in the headspace.
Brewery Line Equipment Beyond the Filler
Bottle Washers (returnable glass): Essential for markets using returnable glass systems. Krones Lavatec and KHS Innoclean are the benchmark machines. Evaluate caustic tank condition (wall thickness measurement), spray nozzle coverage, label removal efficiency, and energy consumption. A well-maintained bottle washer operates for 25-35+ years.
Pasteurisation: Tunnel pasteurisers apply precisely controlled heat treatment to filled and sealed containers. Standard for mainstream beer to ensure microbiological stability. Evaluate zone temperature accuracy, belt condition, and water circulation systems. Krones, KHS, and Sander Hansen are primary manufacturers.
Flash Pasteurisation: Inline heat treatment before filling. Increasingly popular for craft beer as it reduces thermal impact on flavour compared to tunnel pasteurisation. Used flash pasteurisers from Alfa Laval and GEA are available.
Bottle Inspectors: Empty bottle inspection (Krones Linatronic, HEUFT InLine IXS) is essential for returnable glass to detect residual liquid, foreign objects, and glass defects. Full bottle inspection (Krones Checkmat, HEUFT VX) verifies fill level, cap presence, and label position.
Crowners and Cappers: Crown cap applicators (Krones, KHS, Arol, Zalkin) for standard beer bottles. Screw cap adapters for craft beer long-neck formats. Verify cap chute and pocket star condition.
Cold Glue Labellers: Traditional paper label application using cold glue (starch-based adhesive). The dominant labelling technology for beer in many markets. Krones Solomatic and KHS Innoket are standards. Check label magazine, glue roller, and gripper cylinder condition.
Craft Brewery Packaging Solutions
The craft brewery revolution has created enormous demand for small to mid-range used packaging equipment:
Entry-level bottling (1,000-5,000 BPH): Semi-automatic or compact automatic lines. Used machines from smaller Italian manufacturers (MBF, GAI, IC Filling Systems) and reconditioned equipment from larger manufacturers. Budget: €50,000-€200,000 for a basic fill-cap-label line.
Growth-stage bottling (5,000-15,000 BPH): Fully automatic rotary lines. Used Krones, KHS, and Simonazzi fillers become accessible at this speed range. Budget: €200,000-€600,000 for a complete glass bottling line.
Craft canning (50-400 CPM): The fastest-growing segment in craft brewery packaging. Used canning lines from Wild Goose, Cask, Oktober, and CFT. Budget: €80,000-€400,000.
Mobile canning: Contract mobile canning services use truck-mounted canning lines that visit breweries for filling runs. Some used mobile canning systems appear in the market. An alternative to owning equipment for very small producers.
Key considerations for craft breweries: Flexibility for multiple formats (bottle sizes, can sizes), easy CIP cleaning between batches, manageable operator skill requirements, and compact footprint for typically space-limited craft brewery premises.
Market Analysis and Acquisition Strategy
Market supply drivers: The ongoing consolidation in the global brewing industry is the primary source of used brewery packaging equipment. When large brewing groups close or restructure production sites, complete lines become available.
Regional market patterns: European breweries (particularly Germany, Belgium, UK, and Czech Republic) are the richest source of used brewery equipment due to the continent's dense brewery landscape and tradition of investing in higher-specification equipment.
Price stability: Used brewery equipment maintains stable value due to the specialised nature of beer filling technology and the heavy-duty construction required. Lines from the 2005-2015 era offer the best value-to-performance ratio.
Complete line vs components: For breweries expanding into packaging from draft-only operations, complete used lines offer the simplest path. For established operations upgrading specific machines, individual components provide targeted improvements.
Due diligence checklist for brewery equipment:
1. Request TPO (Total Packaged Oxygen) measurement records
2. Verify pasteurisation unit (PU) delivery accuracy
3. Inspect CIP system thoroughly (chemical tanks, pumps, valves)
4. Test inspection equipment with known defect samples
5. Verify CO2 recovery system condition (if applicable)
6. Review maintenance records and spare parts consumption history
BottlingScout provides specialised expertise in brewery packaging equipment, helping breweries of all sizes find the right used equipment matched to their specific production requirements and quality standards.
Frequently asked questions
What dissolved oxygen level should a used beer filler achieve?
Modern beer fillers should achieve total packaged oxygen (TPO) below 100 ppb, with higher-specification machines below 50 ppb. When evaluating used fillers, request recent TPO measurement records. Higher oxygen levels may indicate valve wear, seal deterioration, or inadequate CO2 purging that requires remediation.
Is a tunnel pasteuriser necessary for craft beer?
Not always. Many craft breweries rely on proper sanitation and cold-chain distribution instead of pasteurisation. However, for shelf-stable products, export, or warm-climate markets, pasteurisation is essential. Flash pasteurisers offer lower thermal impact than tunnel systems.
What is the minimum investment for a used craft brewery bottling line?
A basic semi-automatic glass bottling line (fill, cap, label) capable of 1,000-2,000 BPH can be acquired used for €50,000-€100,000. Fully automatic lines start at approximately €150,000-€200,000 for 3,000-5,000 BPH capacity.
Can I fill both bottles and cans on the same line?
Generally no — bottle and can filling are separate operations requiring different equipment. However, some upstream (mixing, carbonation, pasteurisation) and downstream (case packing, palletising) equipment can be shared between bottle and can lines operating in the same facility.
