can you help?!

Is it possibly "Eiswein" rather than "Liswein"? That would indicate a very special dessert wine with concentrated ripe flavor and sweetness (grapes harvested after a frost and only a few drops of grape juice pressed from the partly crystalized grapes so it takes many grapes to produce a bottle).
The Nahe area produces some good wines. Bad Kreuznach is one city known for its annual Weinfest and maybe as a bottling or distribution center for the Nahe, but I'm not familiar with some of the smaller towns along the Nahe or the Munsterer Romerberg vineyard.
It should be an enjoyable wine and very special if it is indeed an Eiswein. Eisweins are usually quite expensive and sometimes sold in half-size bottles 375 ml to keep the price from being astronomical. Some Eisweins might sell for $40-50 for the 375 ml bottle. What vintage?
