What distinguishes Ginjo sake from other types?

Ginjo sake is characterized by its specific polishing ratio of the rice used in its production. A polishing ratio of 60% or less means that at least 40% of the rice grain’s outer layer has been polished away, which significantly enhances the sake's flavor and aromatic profile.

This level of refinement is crucial, as it allows for the development of the delicate and fruity characteristics that define Ginjo sake, setting it apart from other sake types. For example, other classifications, like Junmai-shu or Honjozo, have higher polishing ratios, which do not emphasize the same refinement and aroma profile. Thus, the correct answer highlights the crucial aspect that defines Ginjo sake.
