Knipperlé is a traditional French variety of white wine grape from Alsace.
It's not listed for use in AOC wine, but is a minor component of blends for local drinking, in some ways an Alsatian equivalent of its sibling Aligoté in Burgundy.
DNA fingerprinting has shown that it is one of many grapes to be the result of a cross between Gouais blanc (Heunisch) and Pinot, making it a full sibling of famous varieties such as Chardonnay.
Other Gouais blanc/Pinot crosses include Aubin vert, Auxerrois, Bachet noir, Beaunoir, Franc Noir de la Haute-Saône, Gamay Blanc Gloriod, Gamay, Melon, Peurion, Romorantin, Roublot, and Sacy.
Knipperlé is a parent of the following grapes, mostly riparia hybrids with Millardet et Grasset 101-14 : Bon noir, Colmar Precoce noir, Fin noir, Gutkniperle, Kuhlmann 252-3, Kuhlmann 274-1, Millardet Et Grasset 101-14 X Ortlieber, Neron, Triomphe D'Alsace, Victoire[1] The vine is vigorous but yields are variable, and it is particularly susceptible to grey rot.
