The following is an excerpt from a full report published by WRAP (Waste & Resource Action Programme, UK) from May 2008. The report was prepared as part of the WRAP-funded GlassRite suite of projects which were intended to reduce the volume of packaging entering the UK waste stream. The GlassRite-Wine project has the objective of seeking to promote the bulk importation of wine into the UK to be filled in lightweighted bottles. This report is concerned with the effects of bulk transportation on the quality of wine. The report examines the practice of shipping wine in bulk for bottling close to the final market and its impact on wine quality.
This report finds that the practice of bulk importation of wine does not impair quality and has some environmental and logistical advantages; specifically it concludes that:
- Bulk wine is less prone to experience large temperature variations during transit, as a larger single volume of liquid has a greater thermal inertia than a smaller one. Transporting wine in bulk volumes will therefore lessen the temperature variation experienced. High temperatures accelerate wine development and, in bottles this can cause pressures that can compromise closures;
- Apart from top end wine specifically made with bottle ageing and longevity in mind, wine effectively begins to deteriorate from the time it is filled into bottles and its is at this filling point that the shelf life is deemed to start. Bulk shipping defers the moment of bottling and thus the start of the shelf life. This has implications for the retailer in regards to stock levels and rotation, as the entirety of the shelf life is spent in the country of sale rather than during transport, which may be an advantage for entry level wines with a more limited shelf life;
- Bulk shipments are more cost effective. A standard container typically holds 12,000 to 13,000 bottles, whilst a standard flexitank holds the equivalent of approximately 32,000 bottles. This improved utilization translates into a cost saving;
- Bulk shipments are a better environmental option that transporting bottled wine from the producer country. By more than doubling the amount of product that can be shipped in a standard container and by avoiding the transport of bottles, bulk importing greatly reduces environmental emissions associated with transport;
- The finished product is filled closer to the final market. Filling and packaging close to market may also give the sellers more flexibility to change packaging formats to meet changing market demands and even enable them to respond to short term promotional campaigns; and
- Damage to packaging e.g. bottle and label scuffing, may be reduced if the product is filled locally to the point of sale and problems that do occur can be readily resolved with a local supplier.
On balance the report concludes that the practice of bulk importing wines need have no adverse quality implications on the wine and brings actual benefits with respect to cost efficiencies, carbon emission reductions and recycling.
