Sensory profile

A variety brought back into cultivation
Tsurunashi Genji was revived by the house from a small number of seedlings after it had become difficult to find. Before mashing, the sweet potatoes are rested for about two weeks. This step is part of the product’s aromatic design, drawing greater potential from the material before fermentation begins.
Fragrance with an atmospheric-distilled core
Released in 2013 as the distiller’s signature expression, YASUDA combines black sweet-potato koji, i-33 yeast and atmospheric distillation. Lychee, muscat and rose-like notes sit above a richer central structure.
