Goshosen Genjo-shu" is the source of ginjo-shu, which is slowly fermented at low temperature for a long time, using only sake brewing rice that is more expensive than Koshihikari rice.
It is dry, which is rare for Kamishin. It is also fruity because it uses "Okayama Hakuto Yeast" extracted from the peel of Okayama Prefecture's famous white peaches.
