Malbec

Cot, originating from the Cahors region (F) and taking its name from a contraction of Cahors, became widespread in Argentina from the late 19th century under the name of its propagator, a winegrower called Malbeck. DNA tests have revealed that it's a natural cross between Prunelard (from Tarn) and Magdeleine Noire des Charentes, an old variety that has almost disappeared and is also the ancestor of Merlot. Malbec and Merlot are therefore half-siblings. In Switzerland, this variety which is prone to coulure gives a spicy touch to blends.
