Introduction｜Is the Taste of Sake Determined by Rice?

Sake is a simple beverage made only from “rice, koji, and water.”
Among these, rice plays a key role in defining its flavor profile.

Unlike the rice we eat daily, sake is often brewed using a special type of rice called “Shuzo Kotekimai” or sake brewing rice.

In this article, we’ll clearly explain what sake rice is, the different varieties, and how it influences the taste of sake — even beginners can easily understand.

What Is Sake Rice (Shuzo Kotekimai)?

Shuzo Kotekimai is rice specially bred and cultivated for sake brewing.
It has four main characteristics:

1. Large “Shinpaku” (Starchy Core)

The shinpaku(心白) is a white, opaque core at the center of the grain, rich in starch and ideal for koji mold to grow.

2. Ideal Water Absorption and Solubility

It has the perfect properties to absorb water and dissolve gradually during fermentation.

3. Large Grains, Resistant to Polishing

Even after high polishing (seimai), the grains remain intact, making it suitable for premium ginjo sake.

4. Low Protein and Fat Content

Fewer proteins and fats mean fewer off-flavors and a cleaner, refined taste.

Thanks to these traits, sake rice produces sake with depth, purity, and a more sophisticated flavor.
