The white grape variety is an interspecific new variety between Florida D 6-148 x Cardinal. Synonyms are Blanc Dubois and Florida H18-37. It was named after the French winemaker Émile Dubois, who was prominent in Florida in the 19th century. It contains genes of Vitis aestivalis, Vitis labrusca and Vitis vinifera. The hybrid was crossed in 1968 by John A. Mortensen at the University of Florida (USA). The very early maturing vine is resistant to Pierce disease and downy mildew, but susceptible to black rot and anthracnose. It produces aromatic white wines without foxton, with citrus aromas and a subtle muscatel tone. These are used for sparkling and port style wines. The variety, which is well suited to humid, climatic conditions, is cultivated in the US Gulf States of Florida, Georgia, Louisiana, South Carolina and mainly Texas. In 2016, a total of 81 hectares of vineyards were designated (Kym Anderson).
The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.Andreas Essl
