(1)  Characteristics of the liquor essentially due to the producing region

A  Characteristics of the liquor

(A) Sensory elements

The wine of Yamanashi is well balanced representing the characteristics of grape varieties in respect to flavours and taste. These characters have been created by the selection of grape varieties and amelioration of method of cultivation for Koshu, Muscat Bailey A which have been traditionally grown for many years as well as for varieties-Vinifera originated in Europe.

In particular, the wine of Koshu variety provides rich flavors and mild taste, and vivid acidity and fruity flavors of citrus for dry Koshu wine. The wine from Muscat bailey A provides beautiful red and purple robe and luxurious nose hinting sweetness as well as mild astringent of tannin.

White wines from Vinifera provides mild acidity and inherent flavors of Vinifera, in addition, rich volume in the mouth, Red wines from Vinifera provides beautiful color and well balanced taste between solid body with tannin and rich taste.  

(B) Chemical elements

Yamanashi wine shall meet the following requirements with regard to alcohol content, total SO2, volatile acid, and total acid, including sparkling wine.

a) Alcohol content shall be not less than 8.5% and no more than 20.0%.however, in case of addition of sugar, the alcohol content of the wine shall be no more than 15.0%. In case of sweet wine (the minimum residue of sugar is 45g/L or more), the alcohol content shall be not less than 4.5%.

b) Total SO2 shall not be more than 250mg/L, except for sweet wine.

c) Volatile acid shall not be more than 1.2g/L for red wine, and shall not be 1.08g/L for white and rose wine.

d) Total acid shall not be less than 3.5g/L

B Factors for the characteristics to be essentially due to the production region

(A)  Natural elements

Yamanashi prefecture is a mountainous region surrounded by the Akashi high mountain ranges lying
in the west border of the prefecture and high mountains of Fuji  mountain ranges extending to north-east from the south border of the prefecture. Du to the low influence of the ocean, the temperature goes up higher in day time, while it goes down in night. Therefore, the range of temperature in a day is large.

Owing to this topography of the land of Yamanashi, the adverse effects of humidity during the wet season is avoided during grape growing period, and diseases caused by lack of sunshine and strong wind of Typhoons tend to be avoided during maturing time. Coloring of grapes and sugar contents are good in these favourable climate conditions of Yamanashi. The vine growing areas are extended alongside of subsidiary streams of the Fuji river. The soil of the majority of grape growing areas consists of sedimentary rocks and gravels derived from granite and andesite. Moreover, the growing areas are situated in gradients where the layers of soil is deep and the drainage conditions are well, Due to these facts, grapes tend to mature well and wines tend to be well balanced in keeping proper character of grape varieties .    

(B) Elements related to human activities

The production of wine in Yamanashi is said to have started from around 1870. At that time, the surplus of grapes to be consumed as table grapes has been transformed to wine. Therefore, farmers made efforts to increase the production of grapes without fear of overproduction. This fact encouraged the increase of wine production as well.

Since the Meiji era, the government, the prefecture of Yamanashi and local communities supported the development of wine industry by means of institutional arrangements, financial supports, research for breeding grape varieties. At the moment, a wine center has been established in the Industrial Technological Center of Yamanashi Prefecture, and a department for wine grapes has been integrated in the Fruit Research Station. These institutions are not only conducting research but also providing technological guidance and assistance to wine makers. They are the scientific and technological groundwork center for the production of high quality wine of Yamanashi. In addition, a fermentation research institute was founded in the Yamanashi University in 1947.

Almost all over Japan, there is high level of precipitation compared to European

countries, and Yamanashi is not the exception of the influence of over precipitation during the vegetation period. In view of alleviating adverse effects of the wet conditions, vignerons of Yamanashi invented covering sheet over the vertical training systems ,and growing grapes at the higher position in the system to prevent from  returns of water drops to grapes from the ground. In adoption of such measures, the production of high quality grapes have been achieved in Yamanashi.

The wine of Yamanashi contain less iron substance, compared with wines produced in overseas, which is a cause of not agreeable smell like fresh fish when the wine is taken with sea foods, Therefore, people in Yamanashi tend to like to take marine products. One of examples is that there are much Susi restaurants in Yamanashi.  Thus, the wine has become popular drink in daily life of Yamanashi’s people, reflecting the fact that the wines of Yamanashi go well with sea foods.
