Thank you Jana for your post. It is exactly what I had posted as well, being married to a Jewish man, and living in Israel myself.
Everything you said is absolutely true. And yes, drunkenness is forbidden by Jews as well as believers, and Jews drink very little.
I also said the wine at Cana was real wine, by implication of the story in its context and should not be re-interpreted to fit modern Christian traditions.
All wine was real wine, and alcoholic. Grape juice was just grape juice.
Jesus was a Jew and we understand Him from His own cultural point of view. 
God bless you Jana.
