Vignoles is a complex hybrid wine grape variety that was developed by J.F. Ravat originally named Ravat 51. According to Ravat, "Ravat 51" was the result of a cross made in 1930 using the complex hybrid wine grape Seibel 6905 (also known as Le Subereux) and a clone of Pinot Noir known as Pinot de corton. Originally named "Vignoles" by the Finger Lakes Wine Growers Association in 1970, genetic testing has recently proved that Vignoles does not share any major genetic markers in common with Seibel 6905 or Pinot Noir. Thus, Vignoles is unrelated to the "Ravat 51" grapevine that was imported into the USA in 1949 and the parentage of Vignoles is currently unknown.
Viticulturally, Vignoles is described as moderately vigorous with moderate yields, late season bud break, an upright and open growth habit, small very compact bunches that are highly susceptible to Botrytis bunch rot, an average of 105 days from bloom to harvest, high sugar with high acid at maturity, average overall disease resistance, and moderate winter hardiness (−10 to −15 °F (−23 to −26 °C)).
Ravat blanc is a white hybrid grape variety that is a crossing of Chardonnay and a Seibel grape. While the Vitis International Variety Catalogue (VIVC) maintained by the Geilweilerhof Institute for Grape Breeding list Seibel 5474 as the second parent,Master of Wine Jancis Robinson notes that other authors list Seibel 8724 as the parent. The grape is often confused with the white hybrid grape Vignoles that is often called just Ravat (or officially Ravat 51).
Created in the 1930s by French grape breeder J.F. Ravat, there were over 600 hectares (1,483 acres) of the grape planted in France in 1958. Today, the grape is more likely to be found in the United States where producers in the Finger Lakes AVA of New York use to it make sweet wines.
Ravat blanc was created in the 1930s by J.F. Ravat in the commune of Marcigny in the Saône-et-Loire department of eastern France that includes the Burgundy wine region. Ravat crossed the Vitis vinifera Chardonnay grape with a hybrid Seibel grape (either Seibel 5474 or Seibel 8724) created by the French viticulturist Albert Seibel. This lineage makes Ravat blanc a "complex" hybrid in that its pedigree includes genes from several Vitis species.
