Hokkaido in northern Japan is a typical subpolar region and wine production using traditional cultivars can be done recently. However, there is an issue that the grapevines have short life spans in snowy central Hokkaido. This study investigates the effect of snow it-self and its interaction with vineyard slope and grape-vine stiffness on physical stress. In comparison of the flatness of the vineyard, the distortion of the basal trunk in the slope zone was greater than in the flat zones in the snowy mid-season. In comparison between cultivars, the distortion of the basal trunk in the flexible 'Kerner' was greater than in rigid 'Gewurztraminer', even in the flat zones. The magnitude of the distortion coincides with the mortality of grapevines. Although the chang-es in distortion showed a transition in just two winter durations, these results suggested a possibility that the snow cover might be linked to one of the physical dam-ages of grapevines in vineyards in heavy snowy regions.
