What does the term nihonshu refer to?

The term "nihonshu" specifically refers to what is commonly known as sake, a traditional Japanese rice wine. The usage of "nihonshu" serves to differentiate this fermented beverage from other alcoholic drinks that might be consumed in Japan or elsewhere. It's important to recognize that "sake" in a broader sense can sometimes refer to all alcoholic beverages in Japan, which is why the term "nihonshu" is employed to clarify that it pertains to the specific type of rice wine made through the fermentation of polished rice, water, yeast, and koji mold. This distinction is central to understanding both the cultural significance of nihonshu in Japanese society and its unique production process compared to other alcoholic beverages.

This clarity avoids confusion with options representing different types of drinks such as beer or spirits, as nihonshu is firmly categorized within the fermented beverages made from rice.
