Discover the grape variety: Cornalin du Valais

Very old vine cultivated in the Swiss Valais, resulting from a natural crossing between the petit rouge(*) and the mayolet. It is the father of red humagne, also called cornalin d'Aoste, the grandfather of durize or petit rouge du Valais or rouge de Fully and a relative of goron. - Synonymy: old red of Valais, red of the country in Switzerland, landroter (for all the synonyms of the grape varieties, click here!). - Description: medium-sized bunches, cylindrical, winged, compact, strong medium-sized peduncles with little lignification; medium-sized berries, spherical or short elliptical, skin of a beautiful bluish black colour with a lot of bloom. The foliage turns completely red in the fall. - Production potential: early budding in the year. Capricious and difficult variety. Particularly likes the limestone soils of well exposed hillsides that warm up quickly enough, lean and well drained. Semi-erect bearing, vigorous with irregular production. Resists well to winter frosts. Susceptible to the main diseases, especially to oidium and grey rot. Also susceptible to magnesium deficiency and stalk dehydration. Maturity: 3rd early season
