Not being an authority on anything, I didn't even know there was a size #7 wine cork, I'm just glad I took the plunge a bought a Portugese floor corker at the get-go.
It will cork everything, except Champagne corks, as I understand it, with ease.
Plus, if a year or so down the road, she loses interest in making wine, you will probably be able to unload it at a profit.
I paid $47 US for mine about a year ago, and they are now selling for over $70 US, tax and all, at my LHBS.
