A classic family tree represents the descendants of a person or another living being, as well as plants such as the grapevine, and is part of genealogy (genealogical research). It is impossible to represent the ancestry of "all" grape varieties, or even just a few, in this form and fails for several reasons. The qualified biologist Andreas Jung notes the following: Although there are many individual parent-offspring relationships, there are no real family trees, as often only the mother is clear and the father is missing, as is the case with the numerous seedlings of Gouais Blanc (White Heunisch). Every seed (kernel) in a berry is in principle a potential new grape variety, but it only becomes one when the kernel reaches the soil, germinates there and grows into a vine. Within a berry with 5 to 6 seeds, the fathers can therefore be 5 to 6 varieties, depending on what pollen was blown in during flowering or transferred to the vine itself.
In the past, you needed a wealth of encyclopaedias and specialist literature to keep up to date in your vinophile professional life. Today, Wine lexicon from wein.plus is one of my best helpers and can rightly be called the "bible of wine knowledge".Prof. Dr. Walter Kutscher
