What is "chasan"

Chasan is a white French wine grape variety grown primarily in the Languedoc wine region. According to the Vitis International Variety Catalogue, the variety is a crossing of Listan and Pinot. However, some sources (such as wine experts Jancis Robinson and Oz Clarke) describe the grape as a crossing between Listan and Chardonnay. All sources agree, however, that the variety was created in 1958 by Paul Truel at the Institut National de la Recherche Agronomique (INRA) - Unité Expérimentale du Domaine de Vassal & Montpellier SupAgro. One possible source for the confusion of the grapes parentage is that a common synonym of several clones of Chardonnay are sometimes listed as Pinot Chardonnay and Chardonnay, itself, was a crossing of Pinot and the obscure French wine grape Gouais blanc.

Chasan is a traditional Chinese pastry that is popular in Jiangsu Province, China, and especially in Huai'an, a historic city which is considered the home of chasan.
