It is also called "Tokay d'Alsace".
The name of this wine is still a mystery. Tokay of Alsace is made 100% from Pinot Gris grape variety which is from Alsace itself or Burgundy and has never been linked with Hungary.

Pinot Gris grape is a very exacting variety with small bluish grains. Its character varies depending on good or bad season. It might be light and fruity or robust.
The Tokay d'Alsace has nothing to do with Hungarian Tokay.

Pinot Gris is a full-body white wine. It is such a rich and round white that it can even replace red wine with a red meat dish. However white meat is generally recommended with Tokay Pinot Gris.
