| Nominal Capacity |
750 ml filled volume |
750 ml nominal capacity; confirm the fill-height reference used by the supplier |
Usually included in the standard bottle quotation |
High |
Check technical drawings, calibrated volume tests, and sample measurements. |
| Bottle Dimensions |
Dimensions must suit the labeler, case packer, pallet pattern, and storage rack |
Common wine-bottle heights are approximately 290–335 mm; diameter is commonly about 70–85 mm, depending on the bottle shape |
Custom dimensions may require a dedicated mold and tooling charge |
High |
Approve a dimensional drawing and test samples on the actual packaging line. |
| Empty Bottle Weight |
Select the lightest bottle that meets strength and appearance requirements |
Approximately 350–650 g for many commercial 750 ml glass wine bottles |
Lower weight can reduce material and freight cost; premium shapes may cost more |
Medium |
Weigh at least 10 samples and compare the average and standard deviation with the specification. |
| Glass Color |
Use flint, antique green, or other approved glass color according to the wine's light-protection needs |
Color should remain visually consistent across the production lot |
Standard colors are generally less expensive than custom colors |
Medium |
Use an approved color standard and inspect samples under consistent lighting conditions. |
| Neck Finish and Closure Fit |
Match the finish to the selected cork, synthetic closure, screw cap, or sparkling-wine closure |
Verify finish type, neck dimensions, sealing surface, and closure compatibility before ordering |
Closure and bottle must be quoted and tested as a complete system |
High |
Conduct torque, insertion, extraction, leakage, and compatibility tests with the intended closure. |
| Glass Strength |
Consistent wall distribution and adequate resistance to impact and internal pressure |
Requirements vary by bottle design; sparkling-wine bottles require substantially higher pressure resistance than still-wine bottles |
Pressure-rated designs may have higher weight, tooling, and testing costs |
High |
Request documented impact, vertical-load, and internal-pressure test results appropriate to the application. |
| Thermal Shock Resistance |
Bottle should tolerate the temperature changes expected during filling, washing, transport, and storage |
Use the test temperature difference and method specified by the applicable glass-container standard or buyer specification |
Include thermal-shock testing in pre-production and periodic quality plans |
High |
Review laboratory records and perform sample testing after simulated process temperature changes. |
| Visual Defects |
No critical defects affecting safety, sealing, or filling performance |
Control checks should cover cracks, stones, blisters, sharp edges, severe seams, and unacceptable distortion |
Agree on defect classifications and inspection-sampling rules before production |
High |
Approve a defect catalogue, golden sample, and incoming inspection plan. |
| Dimensional Tolerance |
Critical dimensions must remain within the approved drawing tolerance |
Use supplier drawing tolerances supported by process capability data; do not rely only on nominal dimensions |
Tooling maintenance and regular measurement should be included in supplier quality costs |
High |
Measure height, diameter, finish, neck ring, base, and weight using calibrated equipment. |
| Supplier Quality System |
Documented quality management system with traceability and corrective-action procedures |
Prefer suppliers with an independently audited quality system, such as ISO 9001 certification, where applicable |
Certification alone does not replace product-specific audits and inspections |
Medium |
Check current certificates, audit reports, process-control plans, and corrective-action records. |
| Food-Contact Compliance |
Glass and any surface treatment must comply with the regulations of the destination market |
Documentation should cover composition, coatings, inks, and other materials that may contact the product |
Request compliance documents before mass production; testing fees may be separate |
High |
Review declarations of compliance, migration or extractables documentation where required, and batch traceability. |
| Minimum Order Quantity |
Order quantity should match annual demand, storage capacity, and cash-flow limits |
Standard bottles generally have lower minimums than custom molds, colors, or decorations |
Small orders usually carry a higher unit price; custom tooling may require a minimum production run |
Medium |
Obtain written terms for minimum order, release schedule, storage, and unused-tooling responsibility. |
| Unit Bottle Cost |
Compare equivalent specifications rather than the lowest headline price |
Indicative bulk pricing for standard 750 ml glass bottles may range from approximately US$0.30 to US$1.20 per bottle, depending on weight, shape, color, volume, and market |
Confirm whether the quote includes packaging, pallets, tooling amortization, inspection, and taxes |
High |
Request a line-item quotation based on the same annual volume and delivery terms. |
| Packaging and Freight |
Bottles should arrive protected from abrasion, breakage, moisture, and contamination |
Compare pallet pattern, carton or layer-pack method, container utilization, breakage allowance, and freight route |
Delivered cost can be materially higher than ex-works price because glass is heavy and fragile |
High |
Calculate landed cost per usable bottle, including freight, insurance, duties, handling, and documented breakage. |
| Lead Time and Capacity |
Supplier should support the required launch date and replenishment cycle |
Confirm sample approval, mold production, production slot, inspection, and shipping lead times separately |
Custom designs commonly require more time than stock bottles |
High |
Request a written production schedule and evidence of available furnace, forming, and packing capacity. |
| Sustainability Performance |
Balance recycled content, bottle weight, transport efficiency, and product protection |
Ask for verified recycled-content information and a clear statement of how it affects color and strength |
Lightweighting can lower material and freight costs, while recycled content may vary by supply region |
Medium |
Review environmental declarations, recycled-content records, energy data, and packaging-reduction plans. |
| Commercial Risk |
Use clear terms for price validity, payment, claims, replacement, and quality disputes |
Document inspection timing, acceptance criteria, claim deadlines, and responsibility for transit damage |
Lowest unit price may not be the lowest total cost if defect or delay risk is high |
High |
Compare contracts, sample-approval conditions, warranty language, and supplier response time. |
