In reply to mick taylor:
Much discussion of this on Wine-Pages, which is another of the places I waste time on the internet! Firstly you should realise that absolutely no-one will insure wine, so if they break then you will lose out.
So you're really looking for the carriers who are least likely to break them. Allegedly DHL and APC (but via their Fragile hand-loading option only) are the best. Inflatable protectors are the way forward.
