Study on Wine-making Characteristics of Kyoho Grape with Two-harvest Per Year in Guangxi

In order to investigate the processing potentials of Kyoho grape with two-harvest per year in Guangxi,the wine-making process was studied and the characteristics of Kyoho grape were explored.The experimental results showed that Kyoho grape harvested in winter could be used for producing high quality dry red wine,but Kyoho grape harvested in summer was not suitable for producing dry red wine and it was good for producing common sweet pink wine.The measurement results suggested that Nanguohong grape wine produced by Kyoho grape harvested in winter was one of the dry red wine products which contained the highest content of resveratrol in China.The use of Kyoho grape to produce grape wine would promote grape industry development in southern wet subtropical areas.
