Will un-galvanized wire damage a grape vine?

I've researched many websites that suggest galvanized wire as the support wire for the vine. I know wire that isn't galvanized will rust much easier, but will the rust damage my grapevine? Thanks!

Will un-galvanized wire damage a grape vine?
The reason for galvanized wire, as you mention, is to help make the wire last longer. Rust on other types of wire will not directly harm the grape plant. The iron oxide is not absorbed by the plant.
Reply:The rust won't damage the grape vines, but the wire will rust quickly and the support for the vines will break. It is really worthwhile to get stronger and better quality wire for your vines. It is a pain to replace wires every few years.
