Made from Japan's most important indigenous grape variety: Koshu. The grapes for this wine are grown on the foothills of Mt. Kayagatake from estate managed vineyards at an altitude of 400 to 700 metres. The vines are planted in distinctively volcanic soils with good drainage, providing excellent growing conditions. The vineyard has a cool climate but also abundant sunshine, allowing the slow maturation of the grapes over long growing season. 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. Committed to the belief 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.
