Carol C, stay away from wines in cartons (some taste good to me, but my wife has a sulfite or similar problem). Most bottled California wine at $10 or more should be OK (without preservatives such as sulfites). Also Washington-Oregon-Alberta-British Columbia should all be OK.
Reporting of sulfites in food and drink is voluntary- I thought sulfites had to be listed, but not true- only if concontrations over a certain amount.
