The grapes to produce Koshu Private Reserve Grace Wine were fermented in stainless steel tanks and then the wine was left on its lees for three months adding weight on the palate and concentrating the flavours. Koshu Private Reserve Grace Wine was made from Japan’s most important indigenous grape variety, Koshu.
The grapes are grown at 500 metres altitude in the elevated Hishiyama district of Katsunama in the Yamanashi prefecture. At this elevation, the cooler aspect allows for a slow maturation of the grapes over a long growing season. The vines are grown in distinctively volcanic soils with good drainage, providing excellent growing conditions for the Koshu grape. Traditional trellis pruning has been cast aside in favour of a modern long cordon training system which helps to control yields; concentrating flavours and sugars to balance the high acidity that occurs naturally in this variety. The grapes were hand harvested at optimum maturity.
Grace Wine was established in 1923, in the Katsunuma province, the birthplace of the Japanese wine industry. The Grace Wine winery believes that great wine is made in the vineyard, they were the first to research and introduce European training and pruning methods introducing such as using long cordon training and Vertical Shoot Positioning in 1990. The wines are made in a modern way to retain the delicate characteristics of this individual and exciting grape variety.
