I wanted to point you in the direction of a couple different websites. The first one is Norton Says. On Norton Says you can plan a trip to Missouri wineries, and find out more about the Norton grape and wine made out of Norton grapes.
The other link is to Missouri Wine Girl blog. Danene works for the wine and grape board that I am a member of, and she has lots of say about Missouri wines.
Also, if you are on facebook, become a fan of Norton Says.
