Hi Jchrise, and welcome to the Wine Board. Your wine started out OK, though a Reisling Spatlese would have preferable to the Sylvaner. However, after ten or fifteen years (or even sooner) the wine died. Always the optimist, would recommend chilling one down, and pulling the plug. Maybe Mother Nature was kind, but probably not.
