Usually wine is imported in bottles, but a new trend has developed where wine is shipped in bags. This doesn't matter in the least. People will still want to drink wine because they don't care how it's shipped: all that is important to them is that it arrives safely for them to enjoy.
Imported wine is worth it even of it shipped in in bags rather than the bottles. It is the contents that matters a lot and not the packaging. However, after it enters the country it is repackaged into bottles for supermarkets and wine stores. Bag-packaging is for easy and safe shipment.
What are we going to do with all the waste plastic that is a by-product produced from oil; no carrier bags still leaves mountains of solid waste plastic; that has to go somewhere; as to not being biodegradable; fine; lots of other things are as well; should we ban those as well; and how many more forests should we chop down for biodegradable paper bags etc; and what is wrong with indestructible products; we could use those to fill up the holes in the earth we make getting out all mining materials; even use them for road building and coating walkways and pavements etc.
The purpose of expensive, imported wine is to present a certain image of a sophisticated wine connoisseur. Shipping imported wine in bags instead of bottles defeats the purpose of buying expensive wines. Most wine connoisseurs would agree that wine should be shipped in a bottle. They would feel that this cheapens the wine. In short, imported wine shipped in bags is not worth it.
