Valutazione dell’attitudine del vitigno a bacca nera Doux d’Henry alla produzione di vini dolci da dessert

Autochthonous vines, particularly in Piedmont production areas, can be an important economic resource as they generally well suited to severe environmental alpine conditions. The present study was undertaken to evaluate two typologies of sweet wines (‘passito’ and fortified wine) from the not aromatic black grape Doux d’Henry variety, produced in the Piedmont areas of the Pinerolese (Turin Province, Piedmont, Italy) up to 700 m above sea level in order to its knowledge and valorization. This cv vine has at first been studied on mechanical properties which are resulted favorable to the drying of the grapes due to high hardness and rather thick of the skin. Wines produced in these experiments showed interesting chromatic and compositional characteristics, particularly from the point of view of volatile components, such as monoterpenols.
