The vine is classified in the botanical taxonomy (hierarchical systematics) according to the table below. There are different systems with partly different grading or designations. Among others, a widely recognised system was created by the German Professor Dr. Bernhard Husfeld (1900-1970), the head of the institute at Geilweilerhof (Siebeldingen-Pfalz). Another was developed in 1967 by the French ampelographer Pierre Galet (1921-2019).
The following system is based on a modern plant system. Valuable information was provided by University Professor Dr. Manfred A. Fischer (Department of Botanical Systematics and Evolutionary Research, Faculty of Life Sciences, University of Wien, Austria) and the German graduate biologist and grapevine researcher Andreas Jung.
Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.Thomas Götz
