Ampelographic characteristics of Gamza N5
Zdravko Nakov, Iliyan Simeonov
Abstract: Gamza N5 was selected at the Institute of Viticulture and Enolody - Pleven by the method of clonal selection from the Gamza variety population. It was recognized by IASAS in 2019 and was confirmed as a new original branch by Order of the Ministry of Agriculture № RD 12-6/10. 04. 2019. The cluster is medium to large, cylindrical-conical, with a medium-sized wing, semi-compact. The berry is medium large, almost spherical. The skin is dark blue, thin, fragile, with abundant wax coating. The consistency is juicy, and the taste is harmonious, neutral. The clones has high fertility and productivity. Does not show a tendency to combing and millerandage. It is sensitive to fungal diseases and low winter temperatures, but has a good recovery ability. Gamza N5 has a good sugar-accumulating ability. The wines have a ruby color, a delicate fruity aroma, pleasant freshness and soft tannins, dense, with a harmonious taste.
