Cabernet Sauvignon - Descendence
Although it does not have as many mutations as Pinot Noir, because it has not been widely used for the production of descendants, Cabernet Sauvignon has been related to other grape varieties. In 1961, a cross between Cabernet Sauvignon and Grenache produced the French wine grape Marselan.
Cygne Blanc is a white grape vine from Cabernet Sauvignon cuttings that was discovered in 1989 in a garden in the Swan Valley, in western Australia. Cabernet Blanc is a cross between Cabernet Sauvignon and an unknown hybrid grape variety that was discovered in Switzerland at the end of the 20th century.
In 1997, a grapevine producing “bronze” grapes was found in the Cleggett Wines vineyards in Australia. They propagated this mutation, registered under the name Malian, and sold clear red wines under that name. In 1991, they began to produce white grapes from one of the bronze cabernet vines. Clegget registered this “white cabernet” under the name Shalistin.
Compared to its mother cabernet, malian seems to lack anthocyanins in its subeepidermal cells and seems to keep them in the epidermis, while shalistin has no anthocyanins in any of its layers. The team that discovered the VVMyBa1 and VVMyBa2 genes, which control grape color, has suggested that a gene involved in the production of anthocyanins has been suppressed in the subepidermis of Malian subeepidermal cells, and has then invaded the epidermis to produce shalistin.
During a series of attempts between 1924 and 1930, the plen of Cabernet Sauvignon was used to fertilize the Vine Glera (the white wine grape used to make prosecco sparkling wine) to create the Italian red grape Incrocio Manzoni 2.15.
In 1983, Cabernet Sauvignon was crossed with the German white wine grape Bronner to create the white Suivignier gray wine grape.
