Wine vine variety

Grape maturity: period II, 3 to 3 and 1/2 weeks after Chasselas.
Cabernet-Sauvignon N has a late bud burst, is vigorous with large-diameter vine shoots under fertile conditions with very long branches (elongated internodes) and lignified tendrils. It requires careful training and pruning, which can be long or short in southern areas, and is relatively slow. Large pruning wounds should be avoided. Removing wood, which is hard, likewise requires considerable time consuming work. Cabernet-Sauvignon N oftentimes produces better results on gravely and draining ground, rather acid and well-exposed. This variety sometimes suffers from black stem and this risk is increased by using certain rootstock such as S04.
Cabernet-Sauvignon N is less susceptible to grey rot. On the other hand, it is very suceptible to wood disease (eutypiosis, esca) and powdery mildew.
The grape clusters and berries are small. Cabernet-Sauvignon N makes wines with very interesting tannic structure with a sustained color when it has reached maturity. These wines are generally suitable for ageing and maturing in wood. This vine variety passes from vegetal aromas to much more pleasant and complex aromas once the wine has reached a proper maturity. On the other hand, when vinified alone as a single variety, Cabernet-Sauvignon N oftentimes lacks body and roundness.
The Cabernet-Sauvignon N clones carry the numbers 685.
