Have Wine Bag, Will Travel
A new product called BottleWise Duo seems to offer a solution. This soft-sided bag fits in your checked luggage and protects one to two bottles. It retails for about $50. The water-proof interior also protects your clothes in the "unlikely event of breakage." (Why does this remind me our the airline attendant schpiel about the "unlikely event of an accident over water"?)
I'm sure this isn't the only product ...
... developed for this purpose, and I'd be interested in hearing about others as well as novel non-commercial ideas for keeping your wine safe.
As the holidays approach, taking wine to friends or bringing it back from vacation destinations is something we think about more often. I like the concept. Do you?
