Genpeishuzo Co., Ltd. produces sake in Fukui Prefecture, with Reirogenpei as its flagship brand. The brewery is known for a six-step fermentation process called rokudanshikomi, which is more elaborate than the standard three-step method, resulting in sake with a rich, solid body and mellow, slightly sweet character. Information about this brewery in English remains limited, but the brand reflects Fukui's tradition of deliberate, layered brewing craft.
