Since September 2007 the vine is the 4th vegetal whose genome has been fully decrypted.
After Arabis (the smallest genome of the vegetable kingdom), the Poplar (to study the properties of wood) and rice (which feeds almost half the planet), it was chosen because of its importance through the cultural heritage of humanity.
Thus, through the work of conservation of old grape varieties, prospecting and new DNA analysis techniques, a team of researchers led by Jean-Michel Boursiquot was able to identify a common parent to the two main varietals of Cahors wine which are Malbec and Merlot : La Magdeleine Noire des Charentes.
Concerning their other parent, it is the Cabernet Franc for Merlot and Prunelard for Malbec, which is a colored and tannic vine, also parent of the third grape variety you can find in Cahors wines : the Tannat.
Cahors wines as Château Paillas wines : This is a family affair.
