The red grape variety (also Baco 43-23) is an interspecific new variety between Cabernet Sauvignon x Couderc 4401 (Oiseau Rouge). It contains genes from Vitis rupestris and Vitis vinifera. The hybrid was crossed by the French breeder François Baco (1865-1947). It was mainly used as a rootstock. In 2016 no stocks were recorded (statistics Kym Anderson).
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".
