Niizawa Sake Brewing Company 株式会社新澤醸造店
This brewery is a pioneer for rice polishing. Working with their local variety of sake rice, Niizawa contract cultivated Kura no Hana, accomplishing a record-breaking polishing ratio of 7% in 2015 after 350 hours of slow polishing. They then carefully brewed the Zankyo Super 7 and matured it for 1 year at sub-zero temperature to create the first product of its kind. Subsequently, the brewery has taken the challenge even further by polishing its Kura no Hana down to the pin prick of the core of the grain at a jaw dropping .85 percent, the polishing process taking 5297 hours and 34 minutes, approximately 7 straight months of polishing, in the machine. The Reikyo, with a 0% polishing ratio, is a triumph and the winner of the ultimate rice polishing competition.
