Taking this sakamai as a linchpin, Yamagata Prefecture introduced a new system in which a brand 'DEWA 33' is licensed for the sake produced in Yamagata Prefecture satisfying five conditions, namely, 'Dewa sansan is used 100%, Yamagata yeast is used, Olize Yamagata, which is a koji mold developed by Yamagata Prefecture, ginjo sake with no added alcohol, and a polishing ratio of 55% or more.'
この酒米を主軸として山形県は「出羽燦々100%使用、山形酵母使用、山形県開発の麹菌オリーゼ山形使用、純米吟醸酒、精米歩合55%以下」の５条件を満たす県産酒に「DEWA33」というブランドを公認する制度を導入した。
