There is a bit of information around and apparently you can convert a UPC to an EAN by adding 0 to the front of it. Some detail on how the number is made up can be found at http://www.ean-int.org/faqadc.html
However, having looked a little further I suspect there is no easy way to convert from an non-US EAN to UPC, unless someone has on online database. There does not appear to be any link between the EAN and UPC number on the same bottle of wine.
Does the place where you get your UPC information also have an EAN database?
It's a shame becuae I really liked the linking features to ratings and other info.
We would really like to hear what you have to say
