Discover the grape variety: Gros Colman

From the South Caucasus, perhaps in Georgia, some writings give it as coming from Russia, a country close to the previous one. For a long time, it was grown in greenhouses, particularly in Belgium, but also in England, France, Holland and Japan. It was rarely cultivated in the field, but a few attempts were made without much success on the banks of the Rhine, in the Tarn et Garonne region and in Thomery in the Seine et Marne region. Today, it is no longer multiplied in nurseries and is therefore in danger of extinction. It is thought to be the result of a natural intraspecific cross between white tigvoasa or furjmony feher - a Romanian variety with female flowers - and black kadarka. There is a clone that takes on a very characteristic purple color in the fall, with larger berries, larger bunches and later ripening.
