“Known as ‘Cosmos,’ Kairyō Shinkō is a sake-brewing rice first cultivated in Akita Prefecture in 1959. It shares the same lineage as Miyayama Nishiki (“Shinkō No. 190”) and is considered its sibling. While Miyayama Nishiki imparts a firm, structured impression, Kairyō Shinkō offers a smooth and flowing flavor profile.”
