What is the characteristic of nigori sake?

Nigori sake is known for its slightly cloudy and unfiltered appearance. This characteristic is due to the fermentation process where the sake is not completely filtered, allowing some of the rice solids to remain suspended in the liquid, which contributes to its unique texture and visual appeal. The cloudiness can range from a fine haze to a more opaque look, depending on the specific production methods used.

The other options do not accurately describe nigori sake. A crystal clear appearance is typically associated with filtered sake, while a very dry taste aligns more with sake styles that have undergone a thorough fermentation and filtration process, resulting in a clean, crisp profile. Highly polished rice generally pertains to the production of premium sake, where the rice is polished to a higher degree to enhance purity and flavor, but this is not a defining characteristic of nigori sake.
