In the meantime I have been learning and finding out some things.
Muscadet de Sèvre et Maine sur Lie is made from Melon de Bourgogne grapes, not Muscat grapes. I think my grapes are Melon de Bourgogne, they seem to have the same small berries and tight clusters.
Second, apparently bourgogne yeast is also used, and so I made my wine with this.
