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 and abundant sunshine, allowing the slow maturation of the grapes over the long growing season. Traditional trellis pruning has been cast aside in favour of a modern long-cordon training system that helps control yields, concentrating flavours and sugars to balance the high acidity naturally occurring 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, such as long cordon training and Vertical Shoot Positioning, in 1990. The wines are made modern to retain the delicate characteristics of this individual and exciting grape variety.
