What is Shinginshu?

Shinginshu (真吟酒) refers to a type of premium sake in Japan, characterized by its high-quality ingredients and careful brewing process. The term “Shinginshu” translates to “True Ginjo” or “Authentic Ginjo” sake, and it typically refers to sake made with highly polished rice and fermented at a cooler temperature. Locals often enjoyed this chilled or at room temperature to fully appreciate its delicate flavors and aromas. It’s a sought-after sake among connoisseurs for its craftsmanship and the expertise required to make it.
Shinginshu History

In the early 1990s, Tomio Saito, then Chief of the Tokyo Regional Taxation Bureau’s Appraisal Office, introduced “flat rice polishing,” a method that removes only the unwanted parts of the rice. And this results in cleaner, more delicate sake. Although there were challenges in implementing this method, the development of new polishing machines has led to a gradual increase in its adoption by sake breweries. Satake later coined the term “Shingin” to encompass the rice, sake, and technology. It is associated with flat rice polishing, marking the beginning of a revolutionary approach to sake brewing.
Shingin Polishing Brings New Life to Locally Grown Eating Rice
Shingin rice polishing is a versatile method suitable for both sake rice and table rice. This makes it possible for breweries to utilize locally grown rice for brewing. This approach is being embraced by Suzuki Sake Brewery in Fukushima, which uses rice from Namie—a town heavily impacted by the Great East Japan Earthquake—for its sake “Iwakikotobuki.” By adopting Shingin, the brewery can craft clean, high-quality sake even with rice polished to 65%, fulfilling local hopes to revive Namie’s sake-making tradition. The resulting product is praised for its Muscat-like aroma and exceptional taste.
What is the new rice polishing technology?

The new rice polishing technology, “Shingin Polishing,” focuses on the shape of the rice during the polishing process. Unlike traditional spherical polishing, Shingin Polishing leaves the rice in its original shape, resembling a flat, rugby ball-like form. This method effectively removes proteins that cause unpleasant flavors in sake. This allow a ginjo sake made from rice polished to 60% to achieve the same aroma and flavor. As a daiginjo sake made from rice polished to 40%. Satake’s new technology, referred to as “Shingin Polishing,” enhances sake quality by efficiently refining the rice for cleaner, more refined taste.
