DRY white wine help

[Pioneer]

Folks, at the ripe old age of 46 I have become engaged to a woman who loves a VERY DRY white wine. I have tried various "dry" chardonay"s and her reply is "too fruity."
I have tried all of the local (Michigan) St. Julian's whites without sucess. Can anyone give me some suggestions. We drink it at meals occassionaly, but mostly want it for romantic nights in front of the fireplace. $10 to $20 a bottle for a price range. Thanks for your help.
