Why doesn't wine have a nutrition label, like all other foods have, including beer?

Answer 1

Because it is illegal to do so.

The wording allowed on wine labels is strictly controlled by national legislation and international agreements and only working that is specifically permitted is allowed -- and nutritional information is not on the list of permitted information.

However, the Co-op store is deliberately breaking the law by putting such information on its own brand wines -- see http://www.winelabels.org/artilleg.htm for a picture.

Answer 2

Where do you live? There's no nutrition labels on beers in the countries I normally visit. In the States because of a fluke in regulation between the FDA and BATF there is nutritional labeling on vinous products (including hard cider and perry, which are just apple and pear wines, after all) of 6.9% alcohol and less.

Answer 3

It sounds like a good idea to me.
