Sake is usually filtered to remove grain solids left behind after the fermentation process; however, nigori sake remains unfiltered, resulting in a far cloudier drink.
Nigori sake is generally the sweetest of all sakes, with a fruity nose and a mild flavor, making a great drink to complement spicy foods or as a dessert wine. Before serving, the bottle is shaken properly to mix the sediment with the sake, to obtain the full range of flavor and its signature look. It is advised that it be served well-chilled, storing it in an ice bucket to keep it from warming up between servings. It is recommended, as with most sakes, to consume the entire bottle once opened before it begins to oxidize, altering its flavor.
In 2010, a brewer from Akita Prefecture came up with a dark version of nigori sake, the color of which is due to the addition of edible finely powdered charcoal.
